About
Cloudflare's API that lets developers execute AI-generated code in secure, lightweight sandboxes that start in milliseconds instead of hundreds of milliseconds like containers. Enables safe execution of agent-written code with 100x faster startup times using V8 isolates.
Why it made the leaderboard
Cloudflare's API for executing AI-generated code in V8 isolate sandboxes that start in milliseconds rather than the hundreds of milliseconds containers need. If your agent writes and runs code per-request, startup latency is the tax — this is built to remove it.
