Use cases
Where fast-langraph earns its place
The speedups scale with state size, invocation volume, and prompt repetition. These are the production shapes where that adds up to real latency and cost wins.

Production RAG agents
Retrieval-augmented graphs that loop, branch, and re-query — without paying twice.
Read use case →Automation / Ops
Long-running stateful agents
Agents that run for minutes or hours, checkpointing large state the whole way.
Read use case →SaaS / Platform
High-throughput agent services
APIs invoking LangGraph thousands of times a minute, where per-invoke overhead is the bill.
Read use case →Hit a LangGraph scaling wall?
We help production teams squeeze every bottleneck out of LangGraph — checkpoints, state, LLM costs, memory. Honest audits. Measurable fixes.
