Maestro

Maestro is EvalOps' native Rust coding agent. One maestro executable owns the CLI, interactive terminal UI, headless protocol, hosted runner, and web control plane. Node.js and Bun are not required to run the product.

Install

curl -fsSL https://raw.githubusercontent.com/evalops/maestro/main/scripts/install.sh | bash
maestro --version

Release assets are named maestro-darwin-arm64, maestro-darwin-x64, maestro-linux-arm64, and maestro-linux-x64. The npm package contains the same native binaries and a POSIX launcher; it does not execute JavaScript at runtime.

Use

maestro                         # interactive TUI
maestro "fix the failing test" # interactive with an initial prompt
maestro exec "summarize this repository"
maestro --headless              # NDJSON protocol over stdio
maestro web --port 3000         # browser UI and HTTP control plane
maestro hosted-runner

Develop

Rust owns every agent/runtime path:

• packages/maestro-rs — canonical executable and command dispatch
• packages/tui-rs — agent core, providers, tools, TUI, and headless runtime
• packages/control-plane-rs — HTTP/SSE/WebSocket control plane

The repository contains no TypeScript source or TypeScript build toolchain. The browser UI is a versioned static asset snapshot served by the Rust control plane; agent execution, protocols, adapters, CLI, and TUI are Rust.

cargo test --workspace --locked
