README

Sovereign

A self-hosted console for controlling your coding agents remotely, on your own machines, from mobile or desktop.

Sovereign is **harness-agnostic**: it is not tied to one agent runtime. It brings tasks, conversations, and diffs into a single interface, with an adapter for each supported harness.

Supported harnesses

Harness	Status
pi	Available
Claude Code	Available
Codex	Planned — not yet supported
OpenCode	Planned — not yet supported

Only one supported harness is needed to use Sovereign. Each new integration requires an adapter; arbitrary CLIs cannot be added through configuration alone. Capabilities such as models, permissions, and session resumption depend on the selected harness.

Repository structure

server/: one Rust server per machine. Manages tasks and sessions through harness adapters, exposes an HTTP + WebSocket API, and serves the PWA.
pwa/: the mobile and desktop interface (Svelte 5, Vite), embedded in the server binary.
landing/: the English and French product website (HTML/CSS/JS, Vite), deployed independently. See its README.

See [PLAN.md](PLAN.md) for the architecture and development history (in French).

Prerequisites on each machine

At least one supported harness installed and authenticated: pi (pi works in a terminal) or Claude Code (claude works in a terminal). The server detects available tools at startup; pi is not required when Claude Code is installed.
Rust (Cargo) to build the server, a
