Ephemeral microVM sandboxes for running untrusted or agent-generated code in isolation — a one-call `sandbox::run`, a create/exec/stop lifecycle, and ten `sandbox::fs::*` file operations.

A full-stack reactive todo app over a single browser-to-engine WebSocket. Function calls and live stream change events flow over the same connection.

{/* <Tip> The tabs above split the site into Docs (start here), Tutorials, How-tos, Patterns, SDK & Engine Reference, and Changelog. Read this page and the Docs tab in order first. The other tabs make more sense once you have the model. </Tip> */}

When you want to bring an existing service (a third-party API, a library, an in-house microservice) into an iii system without rewriting it, wrap it in a thin worker that exposes the service's capabilities as iii functions. The worker translates between the existing service's interface and the iii function-call shape.

{/* TODO: Re-link worker references to https://workers.iii.dev/workers/<name> once the Worker Docs migration ships. */} <Note> This page is a hand-authored snapshot of the planned public surface. The final reference will be generated from the SDK source. The Browser SDK is a standalone implementation alongside the Node SDK, not a build of it. </Note>
