Strengths	+ Fully open source + Multi-model (Anthropic, OpenAI, OpenRouter, local) + Git-native commit-per-change workflow	+ MIT-licensed and developed fully in the open with a large contributor base + Provider-agnostic with 75+ LLM providers, local models, and BYOK support + Privacy-first design that does not store code or context data server-side + Runs in terminal, IDE, and desktop with multi-session support
Tradeoffs	− Less polished than IDE-based harnesses − No managed plugin ecosystem	− Rapid release cadence can bring breaking changes between versions − Result quality varies with whichever provider and model the user configures
