The honest brief
CopilotKit
Ships generative-UI primitives and the AG-UI protocol so agents render live React components and share app state, not just stream chat.
- Connects to LangGraph, CrewAI, LlamaIndex
- Generative UI + shared frontend state
- Headless APIs and prebuilt components
- Wide enterprise production adoption
- Frontend-focused — you bring the agent
- Advanced enterprise features are paid
- AG-UI protocol still maturing
LangGraph
Durable checkpointed state-graph with human-in-the-loop — long agent runs pause and resume, unlike one-shot chains.
- Durable checkpointed state
- Low-level graph control
- Debuggable long-running agents
- Runs in production at major firms
- Steeper learning curve
- More boilerplate than chains
- Tied to LangChain conventions
