I use Claude Cowork and similar tools daily. They're good, but locked to one model, limited filesystem access, and your data goes through their cloud.
OpenYak is an open-source desktop agent that directly reads, writes, and manages files on your machine. 20+ built-in tools, 100+ models (or Ollama offline), BYOK, MCP support. All data stays local.
Tauri v2 + Next.js + FastAPI + SQLite. macOS and Windows. AGPL-3.0.
Early stage — feedback welcome.
