Logpush delivers logs in batches as quickly as possible, enabling Cloudflare to provide information almost in real time. During our recent Birthday Week, we made Logpush available on all self-serve plans and Transformers generally available.
Those changes were among eight major updates to Cloudflare Observability and reflect our commitment to make every Cloudflare feature available to everyone. This post takes a deeper look at how Transformers work inside Logpush's export pipeline. Observability teams use Logpush to export Cloudflare logs to security information and event management systems (SIEMs), analytics platforms, and object storage. Before those logs reach their destination, teams may need to remove health checks, omit sensitive fields, or reshape records for dashboards and investigations. Today, this often requires a separate processing service that teams must deploy, scale, monitor, and maintain.
For example, a team that collects logs from multiple CDNs can add a static provider field to normalize records before they reach its analytics platform. Teams also pay to export, ingest, and store records they discard as soon as they arrive, so filtering them before delivery can reduce downstream data volume and cost.
With Transformers, that processing moves into the Logpush export workflow.Teams define a SQL query Continue reading
Following last week’s release of Clef and Clef-flash, Cloudflare’s open-weight decision models, we decided to bring forth more gifts. Today, we’re releasing Clef-omni, which takes in audio and video input alongside text and image. We also cut the price of Clef-flash so it is now cheaper than Jev, and we made Clef faster.
Although the model game is still early for Cloudflare, innovation and iteration is in our DNA, and we apply these principles to everything we do. In fact, the story of Clef came together over the course of less than a week. We decided we wanted to do something in the decision model space on a Friday evening, trained the model over the weekend, and launched it on Thursday. Even with such a short timeline, we were able to ship performant, high-quality, open-weight models for the community — imagine what more we can do in the future.
For today, we’re excited to keep up the momentum with new additions and improvements to our Clef family of models. This is just the beginning, and we’ll continue to get better, faster, cheaper, and more innovative.
Our new Clef-omni model is able Continue reading
Understanding why an application is using more resources than expected, whether that is CPU or memory, can be challenging. Logs and aggregate metrics can only get you so far. Thankfully there is a better way: CPU or memory profiling can show you the exact function where your application is using CPU or allocating memory.
Today we are happy to announce support for CPU and memory profiling of Workers and Durable Objects. From the Workers Observability page, you can now request an on-demand CPU or memory profile of an active Worker, inspect it as an interactive flamegraph, and download the profile file for further analysis.
This method of profiling gives you a useful perspective into what your code is doing and how you can improve it in a real-world setting. That’s because the best way to understand your application is to profile it in production.
To try this on one of your Workers, you have a choice of using the CLI or the Cloudflare Dashboard.
To use the CLI, make sure you have the cf package installed, then simply run:
To use the dashboard, head to the Cloudflare dashboard and then access the list of Workers on your account Continue reading
The Deno team is joining Cloudflare to radically simplify self-hosting Workers and Durable Objects so developers can use the same primitives in more places.
For what this means and how it came about, here’s the story from Ryan Dahl, Senior Principal Engineer, and Kenton Varda, Distinguished Engineer.
Radar provides a real-time view into global Internet trends, powered by Cloudflare’s global network. We support Cloudflare’s mission to help build a better Internet by making web data visible, clear, and actionable for everyone. Since launching in 2020, Radar has found a natural audience amongst expert users with technical backgrounds, such as network operators and academic researchers who rely on Radar data to observe industry trends and global events.
But Radar also has the potential to be a more regular, self-serve resource for journalists, human rights advocates and policymakers, and everyday users. Making Radar accessible to a wider audience is a core part of our vision, so we knew it was time to reevaluate the user experience: How could we make Radar more approachable to broader audiences, while preserving the depth and rigor that we currently have?
In this blog post, we’ll introduce the redesigned Radar, share our design process, and outline our broader vision for the platform’s future.
While the previous landing page was successful at showing the breadth of Radar’s data, the way that information was presented made it difficult to parse. The bento box layout gave everything similar visual weight, the Continue reading
Security alerts rarely arrive one at a time. A single alert can cause a spike across the environment, requiring a human analyst to decide which alerts are related and what they mean. When multiple arrive at the same time, it can quickly overwhelm even a seasoned security analyst. Enter the alert paradox. Now, our built-in, multi-AI-agent security operations harness can handle more of this work at Cloudflare scale.
Our Cloudflare Managed Defense AI agent harness speeds up the process of gathering data, connecting and aggregating detections, and accounting for missing sources while new alerts continue to arrive. To further analyze context, we make use of the OpenAI Daybreak Defense Network and our partnership with Anthropic. Cloudflare uses approved OpenAI Daybreak and Anthropic models, including GPT-5.6 Cyber and Mythos, for deeper model-backed analysis. Initial analysis and scoring is done with Clef, Cloudflare’s open-source decision model.
Collecting evidence to understand what each alert means requires a lot of time. Even in a highly sophisticated Security Information and Event Management (SIEM), too much is still left for a human to review. Human analysts must gather data, connect and aggregate detections, and account for missing sources while new alerts continue to arrive.
Think about every Continue reading
On October 11, 2026, the DNS root is scheduled to change its key-signing key (KSK) for only the second time ever. This key anchors DNSSEC’s chain of trust, which lets DNS resolvers authenticate answers using cryptographic signatures. The change is called a KSK rollover. Validating resolvers need to trust the new key before the switch, as otherwise healthy websites could become unreachable.
When we wrote about the first root KSK rollover in 2018, we had seen resolvers lose their learned trust in the new key during software upgrades or moves between machines. Publishing the key well in advance was only part of the job. We also needed to know whether resolvers had retained it, and we couldn’t give users a practical way to check.
Most website operators do not need to make any changes for this rollover. If you run a DNSSEC-validating resolver, check that it trusts the new root key, KSK-2024, and follow your software vendor’s instructions to update its trust anchors if the key is missing. If you use Cloudflare for your domain's DNS or rely on 1.1.1.1 and Gateway DNS, you do not need to take any action — our systems already trust Continue reading
We celebrated our 16th birthday last week by sharing how we’re building a better Internet for today’s world. As Matthew and Michelle reflected in this year’s Founders’ Letter, this year saw some of the most consequential changes in the history of the Internet.
For the first time, automated traffic surpassed human activity. AI is empowering people to build like never before, leading the Internet to grow massively in scale and unlocking more ambition and creativity. As we witnessed the influence that agent-driven recommendations have on consumer choices, we identified the need for a new approach that creates space for new businesses to succeed.
Each day of Birthday Week explored a different way we are helping to build the future of the Internet. We began on Monday by strengthening our commitment to open source. Tuesday focused on application security and the post-quantum transition. On Wednesday, we explored new economic models for the agentic Internet. Thursday, we expanded the Developer Platform with new tools for data analysis, storage, AI, and agent development. Finally, we closed out the week by launching features that make Cloudflare faster, easier to operate, and more accessible to everyone. As a special Birthday Week follow-up, we shared Continue reading
A year ago, many companies were cutting intern and new-graduate hiring. We went the other way. We announced a goal to hire as many as 1,111 interns in 2026, a number that’s a nod to 1.1.1.1, our public DNS resolver.
The bet was that AI makes early-career talent more valuable and able to make an impact faster. The best AI tools help people learn a system faster, try more ideas, and take on harder problems. They don’t supply the energy, curiosity and fresh eyes a new person brings to a team.
A year in, and our interns are shipping to our internal teams and to millions of customers.
If you’re reading this on the Cloudflare Blog, you’re already using some of their work. The blog runs on EmDash, and EmDash’s second maintainer started at Cloudflare as an intern this past summer.
We’re still working toward 1,111. So far, we’ve hosted 750 internships across 48 teams in nine offices: Austin, San Francisco, London, Lisbon, New York, Singapore, Bengaluru, Washington DC, and Sydney. And we’re still hiring.
From their first day, interns joined active teams and worked on real problems. Each was expected to leave Continue reading
Cloudflare Stream is a powerful broadcasting platform that, for many of our customers, just works. But what if you wanted to render dynamic annotations on a livestream or create an alternate version of a hosted video with burned-in subtitles? You would need to run a custom video pipeline.
Today, we’re releasing a new developer playground, Streamline, that demonstrates how you can build a system to deliver these bespoke video experiences on Cloudflare’s Developer Platform. We’ll walk you through how Streamline leverages Workers, Containers, and several media protocols to modify video — and immediately publish that output as livestream or new hosted video. You’ll also have the opportunity to try it for your projects.
A processing pipeline needs a durable, long-running environment that can run specialized, compiled code with predictable memory and CPU capacity. Video streams can run for minutes or hours, so the media process needs a lifecycle independent of the request that started it. An application should be able to start a pipeline, send its input, inspect it, and stop it without needing to keep a single request open for the entire duration.
Cloudflare provides the primitives we need. Containers are long-lived runtimes suitable for media processing. Durable Objects Continue reading
Fun fact: when you use an agent and it needs to fetch a live web page, the agent usually just guesses the URL of the page and then makes a tool call to curl it. This is why you’ll sometimes see web fetches come back with a 404 Not Found, which happens if the agent incorrectly guesses the URL of that information. As you can imagine, it’s not super efficient to randomly guess URLs all the time.
There is a better way. What if your agent can actually browse the Internet, just like how humans start with a search engine query when we’re looking for information? This is what web search is designed to do — it enables agents to search for relevant data on the Internet and grounds an agent’s responses based on live information.
Today, we’re announcing Cloudflare’s partnership with web search providers to bring you grounded intelligence via AI Gateway. We’re kicking off this launch with our partners from Ceramic.ai, Exa, and Linkup.
AI models are only as good as the context you feed them. Models are typically trained and then frozen at a point in time, operating only on Continue reading
Cloudflare is now the fastest provider in 74% of the 1,000 largest networks around the world, up from 60% in April 2026. This huge improvement matters because every millisecond affects how quickly users can reach the applications, APIs, and websites they rely on. In this Birthday Week performance update, we’ll review how we get our measurements, introduce a new measurement methodology using Cloudflare Challenge Pages, and discuss where these improvements have had the biggest impact for customers.
In August, Cloudflare was the fastest provider in 74% of top networks, up 14 percentage points from our last update during Agents Week in April. The figure below shows the countries where Cloudflare is the fastest provider.
We improved from 60% to 74% by becoming the fastest provider in an additional 150 networks out of that top 1,000, and there are 38 additional countries where Cloudflare now ranks as the fastest. We measure this by looking at the fastest provider for users on the networks serving the largest number of users in each country.
The graphic below shows countries where Cloudflare has become the fastest provider across those networks since April.
Here you see the number Continue reading
Tracking how governments target dissidents living in exile. Helping people in crisis find mental health support. Advocating for legislation that protects free expression online. These are a few examples of how some of the world's leading organizations are building the future of non-profit work with Cloudflare.
AI is changing how people do their work. The goal of Cloudflare Impact is to help ensure that non-profit organizations are among the first to benefit. Today, we’re sharing what dozens of civil society organizations have built using our developer services with more than $7.5 million of Cloudflare credits. These stories show what is possible when AI applications are accessible, secure, and affordable to build and run.
We believe a better Internet is one that allows people to express themselves online and access a diverse range of viewpoints. A key part of Cloudflare's mission has been making security services available for everyone and helping ensure that individuals and organizations working for the public interest are not forced offline by those more powerful. Today, Project Galileo, which provides free cybersecurity services to civil society organizations, protects more than 3,400 domains across more than 120 countries.
Through these Continue reading
We launched Quick Tunnels in 2021 to give developers an easy way to share their latest service, application, or project running in their local development environment. A lot has changed since then, but the core use case remains the same.
Your coding agent has just finished the feature. The dev server is up on localhost:5173, and before you ask, the agent offers to let you try it on your phone. It runs one command and hands you a link:
That command starts a Quick Tunnel. cloudflared, Cloudflare's lightweight connector, publishes your local service at a random trycloudflare.com URL. No account, no domain, no cost. Agents now use Quick Tunnels for the same reason people do: they are the shortest path from a local port to a URL.
The catch has always been the same. Anyone with the link can open it.
Starting with cloudflared 2026.9.3, you can add --allowed-mail to the command, and your Quick Tunnel only lets in the email addresses and domains you choose. Visitors prove they own one of those addresses with a one-time PIN from Cloudflare Access. Nobody, on either side, needs a Cloudflare account.
Traditionally, preventing online fraud relied on point-in-time proof of identity: enter the correct password, complete a biometric verification, or pass a liveness check, and gain access. To defeat these controls, fraudsters had to steal credentials and other identity evidence from a real user, which was difficult to execute and scale. Today, widespread access to AI enables fraudsters to fabricate or imitate legitimate identities by combining exposed credentials with synthetic media designed to evade identity verification. Consequently, identity checks are no longer sufficient as they capture a moment in time. Even when someone passes a check, it does not mean the account itself can be trusted.
One convincing interaction can be faked. A consistent pattern of legitimate behavior is much harder to manufacture. Modern fraud prevention must move beyond stateless decisions toward a stateful trust model. Traditional identity verification asks, “Can this person pass the check right now?” A stateful approach additionally asks, “Does it fit what we know about this account and its established behavior?” At Cloudflare, trust is continually earned and reassessed at each interaction against historical behavioral, network, and device patterns.
Cloudflare’s Account Abuse Protection (AAP) creates stateful account overviews to help website owners detect and investigate abuse across Continue reading
Today, end users carry too much of the burden of online privacy. To avoid third-party trackers or targeted ads, users are instructed to use a VPN, disable cookies, or install adblockers. Meanwhile, some app developers end up knowing more about their users than they’d care to: a typical client-server exchange creates a trail of user data, like the client’s IP address or TLS fingerprint. This level of visibility can be a burden.
That’s why Cloudflare builds infrastructure that helps developers bake privacy into their apps. Oblivious HTTP (OHTTP) is an IETF standard designed to enable app backends to receive HTTP requests without seeing user IP addresses.
This fall, we’re launching the Cloudflare OHTTP Gateway. Customers will be able to enable our new OHTTP Gateway as a paid add-on to their zone and start receiving OHTTP traffic with just a few clicks. Register through our form to join our waitlist. Read on to learn more.
With OHTTP, requests travel through two independently-operated hops: a relay and a gateway. An OHTTP relay blindly forwards encrypted requests in order to hide client identifiers from app servers. An OHTTP gateway performs the cryptographic work of decapsulating encrypted requests and encapsulating responses Continue reading
A year ago, Cloudflare CTO Dane Knecht announced our intention to make every Cloudflare feature available to everyone. Cloudflare launched an Enterprise tier years ago when larger customers came to us looking for procurement options beyond a credit card, like invoices, custom contracts, and dedicated support. Those offerings met a customer need but over time, a two-tier system developed where some of our most advanced and powerful features were only available to Enterprise customers. Our goal was to close that gap.
Today, teams of every size use Cloudflare, from Fortune 100 enterprises to small businesses, open-source projects, and individuals. Across the platform, we’re committed to ensuring that every user or team can make use of all of Cloudflare’s capabilities in a way that helps their organization thrive.
The underlying philosophy is that Cloudflare should offer products suitable for our most demanding customers — and make those capabilities available to everyone. Large or small, every customer would prefer not to have to call support. Building products that are easy to buy, configure, and consume means more of our products in use and a step closer to a better Internet for everybody.
Every generally available (GA) feature we launched this week that Continue reading
Today, we’re introducing Cloudflare Traces in open beta, extending automatic tracing beyond Workers to the rest of the request path. In one trace, you can see supported security rules, transformations, cache decisions, routing, Worker execution, and origin handling, then continue that trace through services running on Cloudflare, at your origin, or elsewhere in your stack. This is a long-term investment in OpenTelemetry and in making Cloudflare the most observable part of your stack.
You can now:
You can enable tracing in the Cloudflare dashboard on any domain or let your agent set up for you:
Today, we’re launching eight major updates that bring your logs, traces, analytics, alerts, dashboards, and exporting into one observability platform, with simpler and more predictable pricing.
Here's what's launching:
Understanding an issue often requires data from more than one Cloudflare product. A spike in 5xx responses could come from a Worker, from your origin, or from Cloudflare failing to connect to your origin globally or regionally. But investigating it today requires knowing which product owns each signal and how to query it.
Observability should be a platform-wide capability: it should reflect how applications actually behave and give you the complete context needed to resolve an issue. Over the coming months, you’ll see more Cloudflare products, datasets, and workflows become part of Continue reading
