Symphony

Background coding agents,
orchestrated

Assign work, run agents in parallel, and review changes before merging. Choose Builder or Max to keep work running when your laptop closes.

Get started

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 a task to something you can use. Three steps.

01

Open your Matrix computer

Choose a plan and open your private workspace in the browser. Choose Builder or Max for scheduled, always-on work.

02

Give your agent a clear job

Use a Matrix recipe or describe your own task. Add the files and connect the tools your chosen agent needs.

03

Review the result

Open the report, inspect the files, or review the code. Give feedback in the same workspace and keep the work moving.

Install once. Then ask your agent naturally.

Matrix publishes three focused skills for setup, observable cloud work, and safe GitHub projects. Install them for your coding agents with one Matrix-owned command.

Copy for your agent

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.

What will you hand off first?

Start with a research brief, a weekly report, or a bug fix. Keep your agents and their work in one private cloud workspace.
