For LangGraph users
Keep the API. Drop the runtime.
Every line of your LangGraph code keeps working. You're 5 minutes from a Rust engine.
from agentmatic import StateGraph, START, END in place of from langgraph.graph import StateGraph, START, END. That's it. Conditional edges, checkpointers, time travel, HITL — all identical.
What you get on day one
- 10–15× faster traversal. Multi-agent workloads see 8–12× p95 latency drops.
- Built-in resilience. Circuit breakers, retry policies, dead-letter queues — first-class, MIT-licensed.
- Distributed clusters. Coordinator/worker or P2P, self-hosted, gRPC.
- Multi-language SDKs. Same API in Python, TypeScript, Rust, Go, Java.
What you don't lose
- LangChain tools —
from_langchain_tools()bridges any BaseTool. - LangSmith tracing —
as_langchain_runnable()keeps it working. - LangServe deploys — same Runnable interface.
- LCEL composition — same Runnable interface.
- Time travel + HITL + interrupt_before/after — same semantics.
Where to start
- Read the 5-minute migration guide.
- Check benchmarks for the exact wins on your workload shape.
- Open the repo; star it if you like what you see.
LangGraph migration FAQ
Common questions.
Your LangGraph code keeps working. Change one import. Get 10× speed, built-in circuit breakers and DLQs, multi-language SDKs, and no platform fees.
The hosted Platform UI. You get equivalent functionality (persistence, retry, distributed execution) in the open-source core, plus Agentmatic Studio (open-source visual debugger). You self-host.
Yes. Wrap your agent with as_langchain_runnable() and LangSmith traces continue to land. Or use the built-in OpenTelemetry exporter for Datadog / Honeycomb / Tempo.
Average across the migrations we've helped with: 5 minutes for a small graph, 30 minutes for a multi-agent supervisor with custom checkpointer, 2 hours for a production deployment with CI / observability re-wiring.
