About
The project, called Harness in its README, is a native desktop app and CLI that shows coding agents such as Claude Code, Codex and Cursor side by side across several machines. A daemon on each machine runs agents in tmux, and machines connect directly or through a relay that forwards only ciphertext, sealed with ChaCha20-Poly1305 and X25519 session keys. It also gives each agent its own git worktree and can run local open-weight models through Ollama, MLX-LM and vLLM.
Use cases: coding, other, agent-orchestration, version-control
