Bringing a unified developer experience to Cloudflare Workers and Pages

Today, we’re thrilled to announce that Pages and Workers will be joining forces into one singular product experience!

We’ve all been there. In a surge of creativity, you visualize in your head the application you want to build so clearly with the pieces all fitting together – maybe a server side rendered frontend and an SQLite database for your backend. You head to your computer with the wheels spinning. You know you can build it, you just need the right tools. You log in to your Cloudflare dashboard, but then you’re faced with an incredibly difficult decision:

Cloudflare Workers or Pages?

Both seem so similar at a glance but also different in the details, so which one is going to make your idea become a reality? What if you choose the wrong one? What are the tradeoffs between the two? These are questions our users should never have to think about, but the reality is, they often do. Speaking with our wide community of users and customers, we hear it ourselves! Decision paralysis hits hard when choosing between Pages and Workers with both products made to build out serverless applications.

In short, we don’t want this for our users — Continue reading

Before we launched Pages back in April 2021, we knew it would be the start of something magical – an experience that felt “just right”. We envisioned an experience so simple yet so smooth that any developer could ship a website in seconds and add more to it by using the rest of our Cloudflare ecosystem.

A few months later, when we announced that Pages was a full stack platform in November 2021, that vision became a reality. Creating a development platform for just static sites was not the end of our Pages story, and with Cloudflare Workers already a part of our ecosystem, we knew we were sitting on untapped potential. With the introduction of Pages Functions, we empowered developers to take any static site and easily add in dynamic content with the power of Cloudflare Workers.

In the last year since Functions has been in open beta, we dove into an exploration on what kinds of full stack capabilities developers are looking for on their projects – and set out to fine tune the Functions experience into what it is today.

We’re thrilled to announce that Pages Functions is now generally available!

In May 2022, we announced our quest to simplify databases – building them, maintaining them, integrating them. Our goal is to empower you with the tools to run a database that is powerful, scalable, with world-beating performance without any hassle. And we first set our sights on reimagining the database development experience for every type of user – not just database experts.

Over the past couple of months, we’ve been working to create just that, while learning some very important lessons along the way. As it turns out, building a global relational database product on top of Workers pushes the boundaries of the developer platform to their absolute limit, and often beyond them, but in a way that’s absolutely thrilling to us at Cloudflare. It means that while our progress might seem slow from outside, every improvement, bug fix or stress test helps lay down a path for all of our customers to build the world’s most ambitious serverless application.

However, as we continue down the road to making D1 production ready, it wouldn’t be “the Cloudflare way” unless we stopped for feedback first – even though it’s not quite finished yet. In the spirit of Developer Week, there is Continue reading

D1: our quest to simplify databases

D1: our quest to simplify databases
D1: our quest to simplify databases

When we announced D1 in May of this year, we knew it would be the start of something new – our first SQL database with Cloudflare Workers. Prior to D1 we’ve announced storage options like KV (key-value store), Durable Objects (single location, strongly consistent data storage) and R2 (blob storage). But the question always remained “How can I store and query relational data without latency concerns and an easy API?”

The long awaited “Cloudflare Database'' was the true missing piece to build your application entirely on Cloudflare’s global network, going from a blank canvas in VSCode to a full stack application in seconds. Compatible with the popular SQLite API, D1 empowers developers to build out their databases without getting bogged down by complexity and having to manage every underlying layer.

Since our launch announcement in May and private beta in June, we’ve made great strides in building out our vision of a serverless database. With D1 still in private beta but an open beta on the horizon, we’re excited to show and tell our journey of building D1 and what’s to come.

The D1 Experience

We knew from Cloudflare Workers feedback that using Wrangler as the mechanism to create Continue reading

Build your next big idea with Cloudflare Pages

Build your next big idea with Cloudflare Pages

Have you ever had a surge of inspiration for a project? That feeling when you have a great idea – a big idea — that you just can’t shake? When all you can think about is putting your hands to your keyboard and hacking away? Building a website takes courage, creativity, passion and drive, and with Cloudflare Pages we believe nothing should stand in the way of that vision.

Especially not a price tag.

Big ideas

We built Pages to be at the center of your developer experience – a way for you to get started right away without worrying about the heavy lift of setting up a fullstack app.  A quick commit to your git provider or direct upload to our platform, and your rich and powerful site is deployed to our network of 270+ data centers in seconds. And above all, we built Pages to scale with you as you grow exponentially without getting hit by an unexpected bill.

The limit does not exist

We’re a platform that’s invested in your vision – no matter how wacky and wild (the best ones usually are!). That’s why for many parts of Pages we want your experience to be Continue reading

Introducing Pages Plugins

Introducing Pages Plugins
Introducing Pages Plugins

Last November, we announced that Pages is now a full-stack development platform with our open beta integration with Cloudflare Workers. Using file-based routing, you can drop your Pages Functions into a /functions folder and deploy them alongside your static assets to add dynamic functionality to your site. However, throughout this beta period, we observed the types of projects users have been building, noticed some common patterns, and identified ways to make these users more efficient.

There are certain functionalities that are shared between projects; for example, validating authorization headers, creating an API server, reporting errors, and integrating with third-party vendors to track aspects like performance. The frequent need for these patterns across projects made us wonder, “What if we could provide the ready-made code for developers to add to their existing project?”

Introducing Pages Plugins!

What’s a Pages Plugin?

With Pages Functions, we introduced file-based routing, so users could avoid writing their own routing logic, significantly reducing the amount of boilerplate code a typical application requires. Pages Plugins aims to offer a similar experience!

A Pages Plugin is a reusable – and customizable – chunk of runtime code that can be incorporated anywhere within your Pages application. A Continue reading

A new era for Cloudflare Pages builds

A new era for Cloudflare Pages builds

Music is flowing through your headphones. Your hands are flying across the keyboard. You’re stringing together a masterpiece of code. The momentum is building up as you put on the finishing touches of your project. And at last, it’s ready for the world to see. Heart pounding with excitement and the feeling of victory, you push changes to the main branch…. only to end up waiting for the build to execute each step and spit out the build logs.

Starting afresh

Since the launch of Cloudflare Pages, there is no doubt that the build experience has been its biggest source of criticism. From the amount of waiting to inflexibility of CI workflow, Pages had a lot of opportunity for growth and improvement. With Pages, our North Star has always been designing a developer platform that fits right into your workflow and oozes simplicity. User pain points have been and always will be our priority, which is why today we are thrilled to share a list of exciting updates to our build times, logs and settings!

Over the last three quarters, we implemented a new build infrastructure that speeds up Pages builds, so you can iterate quickly and efficiently. In February, Continue reading

Introducing Direct Uploads for Cloudflare Pages

Introducing Direct Uploads for Cloudflare Pages

With Pages, we are constantly looking for ways to improve the developer experience. One of the areas we are keen to focus on is removing any barriers to entry for our users regardless of their use case or existing set up. Pages is an all-in-one solution with an automated Continuous Integration (CI) pipeline to help you build and deploy your site with one commit to your projects’ repositories hosted on GitHub or GitLab.

However, we realize that this excluded repositories that used a source control provider that Pages didn’t yet support and required varying build complexities. Even though Pages continues to build first-class integrations – for example, we added GitLab support in November 2021 – there are numerous providers to choose from, some of which use `git` alternatives like SVN or Mercurial for their version control systems. It’s also common for larger companies to self-host their project repositories, guarded by a mix of custom authentication and/or proxy protocols.

Pages needed a solution that worked regardless of the repository’s source location and accommodate build project’s complexity. Today, we’re thrilled to announce that Pages now supports direct uploads to give you more power to build and iterate how you want and with Continue reading

Cloudflare Pages Goes Full Stack

Cloudflare Pages Goes Full Stack
Cloudflare Pages Goes Full Stack

When we announced Cloudflare Pages as generally available in April, we promised you it was just the beginning. The journey of our platform started with support for static sites with small bits of dynamic functionality like setting redirects and custom headers. But we wanted to give even more power to you and your teams to begin building the unimaginable. We envisioned a future where your entire application — frontend, APIs, storage, data — could all be deployed with a single commit, easily testable in staging and requiring a single merge to deploy to production. So in the spirit of “Full Stack” Week, we’re bringing you the tools to do just that.

Welcome to the future, everyone. We’re thrilled to announce that Pages is now a Full Stack platform with help from But how?

It works the exact same way Pages always has: write your code, git push to your git provider (now supporting GitLab!) and we’ll deploy your entire site for you. The only difference is, it won’t just be your frontend but your backend too using Cloudflare Workers to help deploy serverless functions.

The integration you’ve been waiting for

Cloudflare Workers provides a serverless execution environment that allows you to create entirely new applications or augment existing ones without configuring or maintaining infrastructure. Before today, it was possible to connect Workers to a Pages project—installing Wrangler and manually deploying a Worker by writing your app in both Pages and Workers. But we didn’t just want “possible”, we wanted something that came as second nature to you so you wouldn’t have to think twice about adding dynamic functionality to your site.

How it works

By using your repo’s filesystem convention and exporting one or more function handlers, Pages can leverage Workers to deploy serverless functions on your behalf. To begin, simply add a ./functions directory in the root of your project, and inside a JavaScript or TypeScript file, export a function handler. For example, let’s say in your ./functions directory, you have a file, hello.js, containing:

// GET requests to /filename would return "Hello, world!"
export const onRequestGet = () => {
  return new Response("Hello, world!")
// POST requests to /filename with a JSON-encoded body would return "Hello, <name>!"
export const onRequestPost = async ({ request }) => {
  const { name } = await request.json()
  return new Response(`Hello, ${name}!`)

If you perform a git commit, it will trigger a new Pages build to deploy your dynamic site! During the build pipeline, Pages traverses your directory, mapping the filenames to URLs relative to your repo structure.

Under the hood, Pages generates Workers which include all your routing and functionality from the source.  Functions supports deeply-nested routes, wildcard matching, middleware for things like authentication and error-handling, and more! To demonstrate all of its bells and whistles, we’ve created a blog post to walk through an example full stack application.

Letting you do what you do best

As your site grows in complexity, with Pages’ new full stack functionality, your developer experience doesn’t have to. You can enjoy the workflow you know and love while unlocking even more depth to your site.

Seamlessly build

In the same way we’ve handled builds and deployments with your static sites — with a `git commit` and `git push` — we’ll deploy your functions for you automatically. As long as your directory follows the proper structure, Pages will identify and deploy your functions to our network with your site.

Define your bindings

While bringing your Workers to Pages, bindings are a big part of what makes your application a full stack application. We’re so excited to bring to Pages all the bindings you’ve previously used with regular Workers!

  • KV namespace: Our serverless and globally accessible key-value storage solution. Within Pages, you can integrate with any of the KV namespaces you set in your Workers dashboard for your Pages project.
  • Durable Object namespace: Our strongly consistent coordination primitive that makes connecting WebSockets, handling state and building entire applications a breeze. As with KV, you can set your namespaces within the Workers dashboard and choose from that list within the Pages interface.
  • R2 (coming soon!): Our S3-compatible Object Storage solution that’s slashing egress fees to zero.
  • Environment Variable: An injected value that can be accessed by your functions and is stored as plain-text. You can set your environment variables directly within the Pages interface for both your production and preview environments at build-time and run-time.
  • Secret (coming soon!): An encrypted environment variable, which cannot be viewed by wrangler or any dashboard interfaces. Secrets are a great home for sensitive data including passwords and API tokens.
Cloudflare Pages Goes Full Stack

Preview deployments — now for your backend too

With the deployment of your serverless functions, you can still enjoy the ease of collaboration and testing like you did previously. Before you deploy to production, you can easily deploy your project to a preview environment to stage your changes. Even with your functions, Pages lets you keep a version history of every commit with a unique URL for each, making it easy to gather feedback whether it’s from a fellow developer, PM, designer or marketer! You can also enjoy the same infinite staging privileges that you did for static sites, with a consistent URL for the latest changes.

Develop and preview locally too

However, we realize that building and deploying with every small change just to stage your changes can be cumbersome at times if you’re iterating quickly. You can now develop full stack Pages applications with the latest release of our wrangler CLI. Backed by Miniflare, you can run your entire application locally with support for mocked secrets, environment variables, and KV (Durable Objects support coming soon!). Point wrangler at a directory of static assets, or seamlessly connect to your existing tools:

# Install wrangler v2 beta
npm install wrangler@beta

# Serve a folder of static assets
npx wrangler pages dev ./dist

# Or automatically proxy your existing tools
npx wrangler pages dev -- npx react-scripts start

This is just the beginning of Pages' integrations with wrangler. Stay tuned as we continue to enhance your developer experience.

What else can you do?

Everything you can do with HTTP Workers today!

When deploying a Pages application with functions, Pages is compiling and deploying first class Workers on your behalf. This means there is zero functionality loss when deploying a Worker within your Pages application — instead, there are only new benefits to be gained!

Integrate with SvelteKit — out of the box!

SvelteKit is a web framework for building Svelte applications. It’s built and maintained by the Svelte team, which makes it the Svelte user’s go-to solution for all their application needs. Out of the box, SvelteKit allows users to build projects with complex API backends.

As of today, SvelteKit projects can attach and configure the @sveltejs/adapter-cloudflare package. After doing this, the project can be added to Pages and is ready for its first deployment! With Pages, your SvelteKit project(s) can deploy with API endpoints and full server-side rendering support. Better yet, the entire project — including the API endpoints — can enjoy the benefits of preview deployments, too! This, even on its own, is a huge victory for advanced projects that were previously on the Workers adapter. Check out this example to see the SvelteKit adapter for Pages in action!

Use server-side rendering

You are now able to intercept any request that comes into your Pages project. This means that you can define Workers logic that will receive incoming URLs and, instead of serving static HTML, your Worker can render fresh HTML responses with dynamic data.

For example, an application with a product page can define a single product/[id].js file that will receive the id parameter, retrieve the product information from a Workers KV binding, and then generate an HTML response for that page. Compared to a static-site generator approach, this is more succinct and easier to maintain over time since you do not need to build a static HTML page per product at build-time… which may potentially be tens or even hundreds of thousands of pages!

Already have a Worker? We’ve got you!

If you already have a single Worker and want to bring it right on over to Pages to reap the developer experience benefits of our platform, our announcement today also enables you to do precisely that. Your build can generate an ES module Worker called _worker.js in the output directory of your project, perform your git commands to deploy, and we’ll take care of the rest! This can be especially advantageous to you if you’re a framework author or have a more complex use case that doesn’t follow our provided file structure.

Try it at no cost — for a limited time only

We’re thrilled to be releasing our open beta today for everyone to try at no additional cost to your Cloudflare plan. While we will still have limits in place, we are using this open beta period to learn more about how you and your teams are deploying functions with your Pages projects. For the time being, we encourage you to lean into your creativity and build out that site you’ve been thinking about for a long time — without the worry of getting billed.

In just a few short months, when we announce General Availability, you can expect our billing to reflect that of the Workers Bundled plan — after all, these are just Workers under the hood!

Coming up…

As we’re only announcing this release as an open beta, we have some really exciting things planned for the coming weeks and months. We want to improve on the quick and easy Pages developer experience that you're already familiar with by adding support for integrated logging and more analytics for your deployed functions.

Beyond that, we'll be expanding our first-class support for the next generation of frontend frameworks. As we've shown with SvelteKit, Pages' ability to seamlessly deploy both static and dynamic code together enables unbeatable end-user performance & developer ease, and we're excited to unlock that for more people. Fans of similar frameworks & technologies, such as NextJS, NuxtJS, React Server Components, Remix, Hydrogen, etc., stay tuned to this blog for more announcements. Or better yet, come join us and help make it happen!

Additionally, as we’ve done with SvelteKit, we’re looking to include more first-class integration with existing frameworks, so Pages can become the primary home for your preferred frameworks of choice. Work is underway on making NextJS, NuxtJS, React Server Components, Shopify Hydrogen and more integrate seamlessly as you develop your full stack apps.

Finally, we’re working to speed up those build times, so you can focus on pushing changes and iterating quickly — without the wait!

Getting started

To get started head over to our Pages docs and check out our demo blog to learn more about how to deploy serverless functions to Pages using Cloudflare Workers.

Of course, what we love most is seeing what you build! Pop into our Discord and show us how you’re using Pages to build your full stack apps.

Cloudflare Pages now partners with your favorite CMS

Interest in headless CMSes has seen spectacular growth over the past few years with many businesses looking to adopt the tooling. As audiences consume content through new interfaces taking different forms — smartphones, wearables, personal devices — the idea of decoupling content with its backend begins to provide a better experience both for developing teams and end users. Because of this, we believe there are and will be more opportunities in the future to utilize headless CMSes which is why today, we’re thrilled to announce our partnerships with Sanity and Strapi and also share existing integrations with Contentful and WordPress — all your favorite CMS providers.

A little on headless CMSes

Headless CMSes are one of the most common API integrations we’ve seen so far among you and your teams — whether it’s for your marketing site, blog or e-commerce site. It provides your teams the ability to input the contents of your site through a user-friendly interface and store them in a database, so that updates can easily be made to your site without touching the code base. As a Jamstack platform, a big part of our roadmap is understanding how we can build our own tools or provide Continue reading

Cloudflare Pages now offers GitLab support

Cloudflare Pages now offers GitLab support

In the early stages of our ideation of Pages, we set out to build a platform with a smooth developer experience that integrates seamlessly with your existing workflow. However, after announcing Pages’ general availability, we realized our platform may not actually be usable by every developer. Before today, only those of you who used GitHub as your source code management tool could take advantage of the Pages experience.

As part of Full Stack Week, we’re opening the doors of our platform to even more users by announcing our integration with GitLab the DevOps platform! You can now create new Pages projects by connecting your repos stored on GitLab and make site changes there via your usual git commands. And what’s more? We’re also launching an official partnership with GitLab to bring you even better integrations with the git provider in the months to come.

Why GitLab?

As a Jamstack platform, our goal is to enable you, the developer, to focus on what you do best — code, code, code — without the heavy lifting! Not only does this mean giving you all the tools you need to build out a full stack site but also provide you with Continue reading

Custom Headers for Cloudflare Pages

Custom Headers for Cloudflare Pages
Custom Headers for Cloudflare Pages

Until today, Cloudflare Workers has been a great solution to setting headers, but we wanted to create an even smoother developer experience. Today, we're excited to announce that Pages now natively supports custom headers on your projects! Simply create a _headers file in the build directory of your project and within it, define the rules you want to apply.

  X-Hiring: Looking for a job? We're hiring engineers

What can you set with custom headers?

Being able to set custom headers is useful for a variety of reasons — let’s explore some of your most popular use cases.

Search Engine Optimization (SEO)

When you create a Pages project, a deployment is created for your project which enables you to get started immediately and easily preview changes as you iterate. However, we realize this poses an issue — publishing multiple copies of your website can harm your rankings in search engine results. One way to solve this is by disabling indexing on all subdomains, but we see many using their subdomain as their primary domain. With today’s announcement you can attach headers such as X-Robots-Tag to hint to Google and other search Continue reading

Cloudflare Pages is Lightning Fast

Cloudflare Pages is Lightning Fast
Cloudflare Pages is Lightning Fast

When we announced Cloudflare Pages in April, our goal wasn’t to bring just any web development tool to the table. As a front-end developer, it’s your responsibility to bring the ideas of your marketing, product and engineering teams to life by crafting a beautifully engaging experience for every customer. With all the hard work that goes into the development process — turning mock-ups to code, getting input from your team, staging and testing changes — you want the best performance possible for your site to showcase your work and optimize your customers’ experience.

Cloudflare Pages is the most secure and most scalable Jamstack platform to build and deploy your sites on the edge. But how is Pages so fast?

It comes down to three key reasons:

  • Pages is built on one of the fastest networks in the world, putting us within 50 ms of 95% of the world’s Internet-connected population. Delivering Pages from this network is the basis of our speed.
  • Cloudflare helps define and implement next generation standards, like QUIC + HTTP/3 and Early Hints, that push Pages performance to the next level.
  • Pages has a killer developer experience that makes it easy to build the fastest websites on Continue reading

Introducing Deploy Hooks for Cloudflare Pages

Introducing Deploy Hooks for Cloudflare Pages
Introducing Deploy Hooks for Cloudflare Pages

With Cloudflare Pages, deploying your Jamstack applications is easier than ever — integrate with GitHub and a simple git push deploys your site within minutes. However, one of the limitations of Pages was that triggering deployments to your site only happens within the confines of committing to GitHub. We started thinking about how users who author content consistently on their site — our bloggers and writers — may not always be editing their copy directly via the code but perhaps through a different service. Headless content management systems (CMSs) are a simple solution to solve this problem, allowing users to store their backend content through an editing interface as a service for an application like Pages.

It made us wonder: what if we could trigger deployments based on updates made in other places rather than just via GitHub? Today, we are proud to announce a new way to connect your Pages application with your headless CMSs and databases: introducing Deploy Hooks for Pages.

What’s a headless CMS?

Headless CMSs such as Contentful, Ghost and allow optimization of content formatting for any type of interface. With tools like these, you can leverage a “decoupled” content management model where all Continue reading
