- Multiple bootstrap modes. Supports terminal, minimal, and custom Python bootstrap configurations.
- Library mode. The core can be imported and used as a Python library in other projects.
- MIT license. Fully open-source with permissive licensing.
- Model-agnostic. Works with any model provider API key you supply.
LangGraph features
- Human-in-the-loop controls. Add moderation and approval steps to keep agents on track.
- Expressive workflow primitives. Create single, multi-agent, or hierarchical flows with low-level building blocks.
- Persistent memory stores. Maintain conversation history and context across sessions.
- Token-by-token streaming. Stream agent reasoning and actions in real time for better UX.
- Model-agnostic runtime. Run agents with any LLM provider using high-level or fine-grained APIs.
- Open-source MIT license. Free to use and modify without licensing fees.
