Deno is joining Cloudflare
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.
Introducing on-demand CPU and memory profiling with flamegraphs for Workers and Durable Objects
On-demand CPU and memory profiling for Cloudflare Workers and Durable Objects is now available. Now you can generate interactive flamegraphs directly in production to quickly track down memory leaks and performance bottlenecks.
Hack the World: Why hackathons are still the best place to learn to build
The barriers to building software have collapsed. Today, anyone can build. Hackathons are a great place to start learning.
Bridging technical depth and usability: The story behind Radar’s redesign
We redesigned Cloudflare Radar to make real-time global traffic and outage data accessible to a wider audience — including journalists, less technical researchers, and everyday users. By introducing an interactive map and standardized components, we simplified navigation while preserving technical depth.
How one bug bounty researcher chooses the features they investigate
As we kick off Cybersecurity Awareness Month, the GitHub Bug Bounty team spotlights @vaib25vicky, exploring their methodology, techniques, and experiences hacking on GitHub.

Building an evidence-grounded agentic security operations harness on Cloudflare
Cloudflare Managed Defense uses a team of specialized AI agents built on Workers and global network telemetry to analyze security alerts. By separating deterministic evidence collection from model inference, the system delivers grounded recommendations to Managed Defense Analysts.
Monte-Carlo simulations
Monte Carlo simulations (or methods ) is the technique of applying randomness and the Law of large numbers to the solution of various scientific and engineering problems. One of its first documented uses was by Stanislaw Ulam and John von Neumann for nuclear weapon simulations after WWII [1] . In this post …
Secret protection must scale with software
Developers aren’t becoming more careless; they’re being outpaced. The tools that let developers create more software should also take on more of the work of protecting it.
The keys to the Internet change on October 11. Are you ready?
On October 11, 2026, the DNS root switches to a new key-signing key (KSK-2024). Learn what this means for you, and how RFC 8509 trust anchor sentinels allow you to test whether your DNS resolver is ready for the rollover.

Building Git infrastructure for agent-scale development
We're rebuilding GitHub's Git infrastructure while GitHub keeps running, creating a foundation for agent-scale software development.
NTS: Authenticated Time at Meta
Meta’s public time service now speaks NTS (Network Time Security, RFC 8915) at nts.meta.com. Packets are authenticated, so a device can verify the time came from us and was not modified on the way. Our NTS servers hold no per-client state. Cookie keys are derived, not stored and not replicated. We’ve open sourced everything, including [...] Read More...

Everything we launched during Birthday Week 2026
We celebrated our 16th birthday with 46 announcements across open source, post-quantum security, AI agents, and developer platform upgrades. Here’s a day-by-day roundup of everything we shipped.
One year later: the power of 1.1.1.1 interns
A year after announcing our goal to hire 1,111 interns, more than 750 early-career builders have shipped real products across 48 teams at Cloudflare. From Birthday Week launches to post-quantum security, our interns prove that AI amplifies human potential instead of replacing it.
ReviewBench: An open benchmark for AI code review
We’re launching ReviewBench, a benchmark for code review agents built on representative GitHub pull requests, multi-source ground truth, calibrated evaluation, and production-aligned metrics.
Streamline: custom video pipelines with Cloudflare Stream and Workers
Streamline demonstrates how to build long-running, continuous video processing pipelines by pairing Cloudflare Workers and Durable Objects with a containerized media engine.
Introducing Web Search API via AI Gateway
Cloudflare AI Gateway now supports native web search API integration in partnership with Ceramic.ai, Exa, and Linkup. Developers can now inject real-time web context into model inference calls via AI Gateway, REST APIs, or Workers bindings.
8 major updates to Cloudflare Observability
Cloudflare is launching eight major updates that bring logs, traces, analytics, alerts, dashboards, querying, and telemetry export into one observability platform, with simpler and more predictable pricing.
Introducing Cloudflare Traces: follow requests through our entire platform
Cloudflare Traces shows how a request moves through security rules, transformations, cache, routing, Workers, and your origin, then follows it across services running anywhere in your stack.
Updates on our pledge to make Cloudflare features accessible to everyone
A year after pledging to eliminate two-tier product access, Cloudflare has expanded Logpush, multi-account governance, and higher platform limits to all accounts. Here is an update on our progress, how we dogfood these tools internally, and what is coming next.
Announcing Cloudflare OHTTP Gateway – expanding access to Cloudflare’s privacy-preserving infrastructure
We’re announcing the closed beta of a self-serve Cloudflare OHTTP Gateway. We’re also renaming our Privacy Gateway to Cloudflare OHTTP Relay to better distinguish the two products.
Follow the thread: a new dashboard to investigate account abuse
Fraudsters are increasingly using AI to bypass stateless security checks. Cloudflare's new Account Abuse Protection dashboard uses stateful analysis and edge-generated Hashed User IDs to help teams investigate and block account abuse.
