Jaz

all your coding agents, living on the board.

A personal AI on machines you own — any agent, loops that run overnight, boards, memory, and git control. Client/server split, always-on, open source end to end.

• Use the major coding agents. Frontier labs are investing heavily in coding agents and benchmarks. Jaz should reuse that work, not reinvent it.
• Bring your existing plans. Sign in with the ChatGPT, Claude, Kimi, Grok, Google, or Meta account you already have, with API keys and open-source agents alongside them.
• Unified memory that you control and can export.
• Connect core apps. Telegram, WhatsApp, Gmail, Calendar, and Slack should plug into the same owned context.
• Open source.

Jaz runs seven coding agents over ACP, and you pick one per thread:

• Pick the agent per thread — any agent in the table above.
• Loops — scheduled prompts that run overnight.
• Boards — multi-window dashboards of live artifacts.
• Memory — survives the thread.
• Ship from the thread — built-in git control.
• MCP servers & skills, token-usage tracking, and an always-on mode for 24/7 work.

Client/server split — the backend owns everything, clients are control surfaces. By default you run both together on your own machine; the backend can also live on a remote server you connect to over HTTP.

• Backend (backend/, Go) — the always-on core. Runs agent sessions, loops, memory, and tools; owns your credentials and workspaces. REST + SSE; drives agents over ACP and tools over MCP.
• Desktop (frontend/, Electron + React) — the control surface. Runs the backend locally by default, or connects to a remote one over HTTP with a per-device token.

Running the backend on a server: see docs/remote-backend.md.

Requirements: Go 1.26, Bun 1.3.5.

Backend:

cd backend
OPENROUTER_API_KEY=... go run ./cmd/jaz   # serves on :5299
go test ./...

Desktop app:

cd frontend
bun install
bun run dev                               # JAZ_API_URL=https://host to target a remote backend
bun run lint && bun run typecheck
bun run build                             # package the desktop app
