Sigil

Watch the machines work.

A self-hosted hub for your terminal sessions — and for the AI coding agents running inside them. Sigil attaches to every machine you own and serves each session as a fast, persistent web terminal, so a long-running agent is observable and interruptible from a browser or a phone. It knows which sessions are working, which are blocked waiting on you, and what they are costing.
