Why I chose LangGraph over LangChain for multi-agent orchestration

State machines beat chains when your agents need to loop, retry, and share context. Here is the architecture that drove the decision.

Multi-agent review systems fail when orchestration stays linear. Real review pipelines branch, retry, and revisit context as new evidence appears.

BugLens is built around that constraint. The Lens agent inspects diffs, the Context agent pulls standards and prior decisions, and the Review agent turns that into a developer-facing verdict.

LangGraph made that statefulness explicit. Instead of encoding complex control flow inside prompts, the workflow remains inspectable and easier to debug as the product grows.
