companion

Why we included this project

Most coding agents live in the terminal, but Companion is built for the times you want to drive them from a phone or browser tab. It launches Claude Code and Codex sessions, streams responses, and lets you approve tool calls without being at your desk. The part that goes beyond a remote UI is the workspace model: a folder of TOML files is the source of truth, and Companion compiles it into a reproducible fleet of specialized agents, each with its own model, tools, memory vaults, and isolated runtime. That appeals to solo developers who want a mobile cockpit for their coding agents, and to small teams that need repeatable client deployments with private Tailscale networking instead of public exposure. Because the workspace is declarative, you can preview and validate a plan before applying it, which gives teams a guardrail around agent operations.
