Announcing connect() — a new API for creating TCP sockets from Cloudflare Workers

Today, we are excited to announce a new API in Cloudflare Workers for creating outbound TCP sockets, making it possible to connect directly to any TCP-based service from Workers.

Standard protocols including SSH, MQTT, SMTP, FTP, and IRC are all built on top of TCP. Most importantly, nearly all applications need to connect to databases, and most databases speak TCP. And while Cloudflare D1 works seamlessly on Workers, and some hosted database providers allow connections over HTTP or WebSockets, the vast majority of databases, both relational (SQL) and document-oriented (NoSQL), require clients to connect by opening a direct TCP “socket”, an ongoing two-way connection that is used to send queries and receive data. Now, Workers provides an API for this, the first of many steps to come in allowing you to use any database or infrastructure you choose when building full-stack applications on Workers.

Database drivers, the client code used to connect to databases and execute queries, are already using this new API. pg, the most widely used JavaScript database driver for PostgreSQL, works on Cloudflare Workers today, with more database drivers to come.

The TCP Socket API is available today to everyone. Get started by reading the TCP Continue reading

IT pros worry about network data being fed to AI tools

As more IT organizations apply artificial intelligence (AI), machine learning (ML), and so-called AIOps technology to network management, network data is critical to success. AI/ML technology requires more and more data to learn individual networks, derive insights, and offer recommendations. Unfortunately, many organizations encounter problems when trying to feed network data to these AI tools.In other words, network teams need to modernize their approach to network data before they embrace AI technology.Enterprise Management Associates recently surveyed 250 IT professionals about their experience with AI/ML-driven network management solutions for a report, “AI-Driven Networks: Leveling up Network Management.” It found that data problems are the number-two technical challenge they encounter when applying AI/ML to network management. Only network complexity is a bigger technical issue.To read this article in full, please click here

Zero Trust Security for AI

A collection of tools from Cloudflare One to help your teams use AI services safely

Cloudflare One gives teams of any size the ability to safely use the best tools on the Internet without management headaches or performance challenges. We’re excited to announce Cloudflare One for AI, a new collection of features that help your team build with the latest AI services while still maintaining a Zero Trust security posture.

Large Language Models, Larger Security Challenges

A Large Language Model (LLM), like OpenAI’s GPT or Google’s Bard, consists of a neural network trained against a set of data to predict and generate text based on a prompt. Users can ask questions, solicit feedback, and lean on the service to create output from poetry to Cloudflare Workers applications.

The tools also bear an uncanny resemblance to a real human. As in some real-life personal conversations, oversharing can become a serious problem with these AI services. This risk multiplies due to the types of use cases where LLM models thrive. These tools can help developers solve difficult coding challenges or information workers create succinct reports from a mess of notes. While helpful, every input fed into a prompt becomes a piece of Continue reading

A raft of free Cloudflare services for AI startups

Over the past couple of years, we have piloted a program for early stage startups with free access to a selection of developer products that are high leverage for them. Last year, we launched version 2 of the startup program, which dramatically expanded the basket of products included.

While upgrading startups to the startup plan, I often get inquiries from startups that are fully bootstrapped and not affiliated with any accelerator program. Many of them, especially AI startups, are very promising and would benefit highly from the startup plan.

Typically, they also apply for the Workers Launchpad program, for whom semi-finalists can get upgraded to the startup plan as a benefit. But many of those startups would benefit from getting upgraded right away rather than wait for the review process for each cohort.

Starting today, AI startups no longer need an accelerator affiliation or an employee referral in order to qualify for the Startup Program.

How to get on the startup plan as an AI startup

Here’s what I need you to do if you are a founder of a bootstrapped AI startup. Create a Cloudflare account if you don’t have one, add a domain, and update Continue reading

Introducing Cursor: the Cloudflare AI Assistant

Today we’re excited to be launching Cursor – our experimental AI assistant trained to answer questions about Cloudflare’s Developer Platform. This is just the first step in our journey to help developers build in the fastest way possible using AI, so we wanted to take the opportunity to share our vision for a generative developer experience.

Whenever a new, disruptive technology comes along, it’s not instantly clear what the native way to interact with that technology will be.

However, if you’ve played around with Large Language Models (LLMs) such as ChatGPT, it’s easy to get the feeling that this is something that’s going to change the way we work. The question is: how? While this technology already feels super powerful, today, we’re still in the relatively early days of it.

While Developer Week is all about meeting developers where they are, this is one of the things that’s going to change just that — where developers are, and how they build code. We’re already seeing the beginnings of how the way developers write code is changing, and adapting to them. We wanted to share with you how we’re thinking about it, what’s on the horizon, and some of the large Continue reading

Introducing Constellation, bringing AI to the Cloudflare stack

This post is also available in 简体中文, 日本語, Deutsch and Español.

The Cloudflare Workers' ecosystem now features products and features ranging from compute, hosting, storage, databases, streaming, networking, security, and much more. Over time, we've been trying to inspire others to switch from traditional software architectures, proving and documenting how it's possible to build complex applications that scale globally on top of our stack.

Today, we're excited to welcome Constellation to the Cloudflare stack, enabling developers to run pre-trained machine learning models and inference tasks on Cloudflare's network.

One more building block in our Supercloud

Machine learning and AI have been hot topics lately, but the reality is that we have been using these technologies in our daily lives for years now, even if we do not realize it. Our mobile phones, computers, cars, and home assistants, to name a few examples, all have AI. It's everywhere.

But it isn't a commodity to developers yet, though. They often need to understand the mathematics behind it, the software and tools are dispersed and complex, and the hardware or cloud services to run the frameworks and data are expensive.

Today we're introducing another feature to our stack, allowing everyone to Continue reading

Query Cloudflare Radar and our docs using ChatGPT plugins

When OpenAI launched ChatGPT plugins in alpha we knew that it opened the door for new possibilities for both Cloudflare users and developers building on Cloudflare. After the launch, our team quickly went to work seeing what we could build, and today we’re very excited to share with you two new Cloudflare ChatGPT plugins – the Cloudflare Radar plugin and the Cloudflare Docs plugin.

The Cloudflare Radar plugin allows you to talk to ChatGPT about real-time Internet patterns powered by Cloudflare Radar.

The Cloudflare Docs plugin allows developers to use ChatGPT to help them write and build Cloudflare applications with the most up-to-date information from our documentation. It also serves as an open source example of how to build a ChatGPT plugin with Cloudflare Workers.

Let’s do a deeper dive into how each of these plugins work and how we built them.

Cloudflare Radar ChatGPT plugin

When ChatGPT introduced plugins, one of their use cases was retrieving real-time data from third-party applications and their APIs and letting users ask relevant questions using natural language.

Cloudflare Radar has lots of data about how people use the Internet, a well-documented public API, an OpenAPI specification, and it’s entirely built on Continue reading
