The outcome
Get into the official LangGraph experience with the right account and a setup you understand.
LangGraph is a open-source orchestration framework and runtime for long-running stateful agents. Designing stateful agent workflows that require explicit control flow, durable checkpoints, streaming, recovery, memory, and human-in-the-loop decisions. This guide narrows that broad capability into one repeatable outcome, with checkpoints that keep the source material and your judgment in the loop.
Before you begin
Set the boundary before the tool starts.
Choose one real task, identify who will use the result, and decide what evidence or test will make the result acceptable. Gather only the source material needed for that task. If the work contains confidential, personal, regulated, or client-owned information, confirm that the platform and account are approved before sharing it.
AI should make the work easier to inspect. If the workflow removes the source, the owner, or the review step, redesign the workflow.
Step by step
A workflow you can repeat.
- 01
Start at https://www.langchain.com/langgraph and confirm the domain before entering account or payment information.
- 02
For desktop use, follow the official download link. Current availability: LangGraph is installed as Python or JavaScript packages and may be run locally or with documented deployment services..
- 03
A supported development runtime, chosen model and tool integrations, and a production persistence layer for durable execution or human review.
- 04
Sign in with the account you intend to keep using, then review plan, data, notification, and permission settings.
- 05
Run one low-risk test task before connecting sensitive files, repositories, or workspace data.
Working standard
What good use looks like.
- Use official download pages.
- Review permissions during setup.
- Keep installers and applications updated.
Durable replay can repeat model calls or external effects unless nodes are designed carefully. Protect persisted state, isolate tenants and threads, use idempotency, control checkpoint retention, and test every interruption and resumption path.
