One substrate,
every shape of compute.

Sandboxes, databases, apps, functions, and schedules compose into the things teams actually ship. Pick the shape that matches yours.

AI agents

Real computers for agents — exec, filesystem, browser, and N-way fork for tree search, behind hardware isolation.

Code interpreter

Run LLM-generated code safely, snapshot between turns, and keep every session in its own kernel.

Preview environments

A full app and a database branch per pull request — built from the PR, torn down on close, $0 while idle.

Full-stack hosting

Deploy an app and attach managed Postgres in one flow — blue-green deploys, scale-to-zero economics.

Background jobs & cron

Ship a bundle, put it on a schedule — every run isolated in its own microVM, with run history built in.

Ephemeral CI

Untrusted PR CI in throwaway microVMs — no runner pool to babysit, no dirty-runner flakes.

Ship on the millisecond cloud.
