Edge runtime
PreviewV8 isolates for latency-sensitive code, with no container to boot. In preview: edge functions are not running for customers yet.
The runtime speaks standard Web APIs — Request, Response, fetch, and streams — so the same code runs at the edge and in your tooling with nothing proprietary to learn. Because isolates share a process instead of booting a container, there's no scheduler queue between a request and your code, and the same deploy serves every request from the moment it goes live.
