Polyphony

Git-native AI orchestration engine. Turn repository events into orchestrated agent work, from issues, PRs, webhooks, or schedules.

---

Polyphony connects your issue trackers to AI coding agents, runs them in isolated workspaces, and shows everything live in a terminal dashboard.

Inspired by OpenAI Symphony, Polyphony brings the same workflow-contract orchestration model to local repositories, but with multiple event sources and multiple agent backends.

Install

brew install penso/polyphony/polyphony

Or build from source:

cargo install --path crates/cli

Then run it inside any git repository:

polyphony

On first start, Polyphony creates a default config at ~/.config/polyphony/config.toml and seeds repo-local agent prompts in .polyphony/agents/.

Events

Polyphony listens for work events from multiple sources:

• GitHub — issues and pull requests
• GitLab — issues via GraphQL
• Linear — issues via GraphQL
• Beads — local Dolt-backed issue tracking

Agents

Plug in any combination of AI coding agents:

• Claude — Anthropic's CLI agent
• Codex — OpenAI's Codex CLI via app-server
• Copilot — GitHub Copilot CLI
• Pi — Warp's Pi agent via native RPC
• OpenAI Chat — any OpenAI-compatible API (OpenRouter, Kimi, etc.)
• ACP / ACPX — Agent Communication Protocol agents and bridges

Each agent gets its own workspace (worktree, directory, or clone), a shared workflow policy, retries with fallback chains, and budget-aware throttling.

Web UI

Polyphony includes a web interface that runs alongside the terminal dashboard. When daemon.listen_port is set, both the TUI and the web UI are available simultaneously:

• SSR dashboard — server-rendered pages for inbox, runs, agents, tasks, and logs
• GraphQL API — query and mutate runtime state, with an interactive playground at /graphql
• WebSocket subscriptions — real-time state updates via GraphQL subscriptions at /graphql/ws
• Jinja templates — HTML templates in crates/httpd/templates/, easy to customize

just httpd          # TUI + web UI on port 8080
just httpd 3000     # TUI + web UI on custom port
just httpd-only     # web UI only (no TUI), port 8080

Or configure daemon.listen_port in your workflow config to always enable the web UI.
