On the Internet, being fast is what matters and at Cloudflare, we are committed to being the fastest network in the world.

We reduced Cloudflare Workers cold starts by 10x by optimistically routing to servers with already-loaded Workers. Learn how we did it here.

It turns out we've all been using MCP wrong. Most agents today use MCP by exposing the "tools" directly to the LLM.

The Cloudflare Data Platform, launching today, is a fully-managed suite of products for ingesting, transforming, storing, and querying analytical data, built on Apache Iceberg and R2 storage.

R2 SQL provides a built-in, serverless way to run ad-hoc analytic queries against your R2 Data Catalog. This post dives deep under the Iceberg into how we built this distributed engine.

We’ve teamed up with PlanetScale to make shipping full-stack applications on Cloudflare Workers even easier.
