Symphony
Background coding agents,
orchestrated
Assign work, run agents in parallel on a computer that never sleeps, and merge only what survives your review.
Symphony orchestrates the work. Assign tasks, run agents in parallel, review only what survives.
Run agents in parallel
Split work across Claude, Codex, Cursor, OpenCode, or Gemini CLI sessions without blocking your laptop.
See status at a glance
Track what each agent is reading, editing, testing, previewing, and waiting on before you review.
Merge what survives review
Keep human control over branches, diffs, checks, browser previews, and PRs.

From signup to autonomous cloud dev. Three steps.
Provision your Matrix computer
Choose power and region, activate billing, and get a private cloud workstation for development.
Connect tools and repos
Open the shell, run GitHub auth, clone the repo, and attach from the web UI or Matrix CLI.
Run agents and workflows
Launch Claude, Codex, Cursor, OpenCode, Pi, Gemini CLI, or Hermes in persistent sessions.
Paste one message. Your agent moves itself into Matrix.
Matrix publishes a setup skill at matrix-os.com/skills.md. Give it to your coding agent so it can install the CLI, guide login, attach to your cloud shell, and start work.

Help me set up Matrix OS, my own cloud dev computer.
Steps:
1. Install the CLI: npm install -g @finnaai/matrix or brew install finnaai/tap/matrix.
2. Run matrix login --profile cloud. It opens a browser/device login that I will approve.
3. If no Matrix instance exists, tell me to sign up at https://app.matrix-os.com, then re-run login.
4. Verify with matrix doctor and matrix whoami.
5. Start my preferred coding agent inside Matrix with matrix run -it --session setup -- claude or matrix run -it --session setup -- codex. I will complete that tool's own login inside the remote terminal.
Do not scan my local machine for credentials or upload secret files. Everything authenticates through its own browser/device flow.Move your agents off your laptop
Start with one cloud workspace. Add agents, tools, workflows, and teammates as the work grows.
