Raven

Raven is an agent that manages other agents. Hand it a big job and it splits the work into a graph of steps, then gives each step to a specialist: its own four (research, code, design, oncall) or ones you already run, like Claude Code, Codex, OpenCode or GitHub Copilot. EverMind, the team behind the EverOS memory engine, ships it free under Apache-2.0.

Setup is one curl script that installs uv, Node.js, Raven, Chromium and, on macOS, LibreOffice. Then raven onboard adds a model provider and raven web opens the browser UI. Memory runs on a local EverOS server by default; EverMind's hosted EverOS Cloud is an optional plugin with no published pricing.

No paid tier; the real cost is tokens: every node in the graph spends your API budget, and the homepage benchmarks ran on Opus-5. Solo: free, worth an afternoon. Small teams: free, for experiments. Larger teams: wait.

The catch: the README calls it pre-alpha and warns that interfaces and configuration may change quickly. The self-improvement pitch and the state-of-the-art charts are EverMind's own numbers, the Curator that rewrites agents is experimental, and giving one young orchestrator command over several coding agents is a lot of trust.
