Technical deep dives, product updates, and insights from the teams that are helping to build a better Internet.
Twelve years after launching Universal SSL, Cloudflare is applying to become a certificate authority. By combining an established root, an ACME-first approach, and Merkle Tree Certificates, we are building a post-quantum CA for the open web.
We’re building CryptoLabe, an internal AI-powered tool that discovers cryptography across our codebase, surfaces dependencies, and helps us progress toward a full post-quantum migration by 2029. Here’s what we’ve learned so far.
Cloudflare introduces an adaptive security framework connecting risk discovery, agent governance, runtime protection, and AI-powered response in a continuous learning loop.
As post-quantum signatures threaten to inflate TLS handshakes and certificate transparency logs, Merkle Tree Certificates offer a path to compact, auditable authentication. Cloudflare’s new certificate authority will support MTC issuance at scale.
We built a WAF tester that adapted each request based on what the WAF blocked or passed. This helped us explore variations that a fixed test might miss. We ran it across six attack categories on an authorized staging environment and discovered detection gaps worth fixing. Here’s how the loop worked, what got through, and what we did about it.
We are expanding access to Cloudforce One's Threat Events Platform to every Cloudflare account and introducing Threat Signals. Threat Signals automatically parses open-source threat reporting, extracts structured indicators, and connects threat context directly to your WAF rules.
Cloudflare has added visibility into post-quantum (PQ) encryption in TLS 1.3 directly into HTTP Analytics, Log Explorer, and Logpush. Learn how to make sure your domain is protected with PQ encryption.
Cloudflare learns the structure of your HTTP requests and identifies deviations. You can add a positive security layer that helps reduce attack surface as AI makes it easier for attackers to generate and vary payloads.
A sophisticated attacker with a quantum computer can exploit a protocol design flaw to downgrade post-quantum IPsec tunnels to classical crypto. We helped the IETF develop a transcript authentication extension to prevent these attacks.
We are releasing cf, our new command-line tool that mirrors the entire Cloudflare API and supports programmatic TypeScript configuration. We are also open-sourcing Forge, our internal SDK generator.
Vinext 1.0 graduates from an AI experiment to a production-ready framework, letting developers run Next.js apps on Vite. This release brings advanced cache warming, broader compatibility, and an automated testing pipeline.
Cloudflare is open-sourcing the BEACON dataset, making billions of anonymized Real User Monitoring (RUM) performance records publicly available on Google BigQuery. Explore real-world Core Web Vitals, soft navigation metrics, and performance breakdowns across browsers and regions.
Since joining Cloudflare, VoidZero has delivered more than 80 releases that drastically speed up JavaScript compilation, linting, and testing. From a 10x faster React compiler to Vite+ 1.0, here’s how we are building faster tools for developers and AI agents.
Forge is a pluggable, open-source pipeline that runs in CI to generate SDKs, CLIs, and documentation directly from API definitions. By shifting generation upstream into individual team repositories, Forge keeps developer tools continuously in sync.
We’ve updated Kitesurf, our Workers-based browser for AI agents, with WebMCP support, improved DOM performance, and terminal-based rendering. With over 730,000 Web Platform subtests passing, agents can now navigate complex sites faster.
Cloudflare is launching The Cold Start, a startup competition giving five early-stage companies five minutes on stage at Cloudflare Connect. Grand Prize winner receives $500,000 in credits, a San Francisco billboard, and an invitation to our VIP speakers dinner.
EmDash 1.0 is a stable, open source CMS built for Astro, with agent-friendly workflows, secure sandboxed plugins, and a decentralized registry that keeps publishers in control.

With the new experimental support for the Emscripten target in Rust Workers, many previously unsupported Rust libraries and applications can now be built and deployed directly to Cloudflare’s global Workers platform, including upcoming support for Tokio async.
The Internet is changing more today than at any point since Cloudflare launched back on September 27, 2010. As automated traffic surpasses human activity, we reflect on the rise of AI agents, new creators, and how we can help build a fair, sustainable future for the web.
