The runtime

Where and how your code executes.

Snippets run in an isolated sandbox at the edge. Cold starts are sub-50ms, and each run is metered so you only pay for execution.

Isolation

Every snippet runs in its own microVM. Untrusted code cannot reach other tenants or the host.

Write TypeScript, Python, or Ruby. Any npm, pip, or gem package is available and installed automatically from your imports.
