Vendor type	open source	open source
Pricing	free	free
Strengths	+ Fully open source + Multi-model (Anthropic, OpenAI, OpenRouter, local) + Git-native commit-per-change workflow	+ Fully open source (Apache 2.0) under neutral Linux Foundation governance + MCP-native extension model with a large extension catalog + Desktop app, CLI, and API interfaces; runs entirely on your machine + Provider-agnostic, including local models via Ollama
Tradeoffs	− Less polished than IDE-based harnesses − No managed plugin ecosystem	− No hosted/cloud offering; users manage their own keys and token spend − Broader general-purpose focus means fewer coding-specific guardrails than dedicated coding harnesses
