LangGraph is LangChain’s framework for reliable agents with low-level control, deployment, observability, evaluation, sandboxes and enterprise LangSmith services.
LangGraph is a AI agent framework for builders who want a real workflow tool, not another vague AI wrapper. The clearest evidence for LangGraph is: Low-level graph orchestration for agents; Durable state and human-in-the-loop flows; Deployment through LangGraph Platform/LangSmith; Tracing and observability; Evaluation workflows; Sandboxed agent execution; Expose an agent as an MCP server. Those details matter because they describe what a team can actually wire into a repository, agent stack, automation system, or browser workflow.
Pricing should be read carefully. Current pricing: Open-source framework: Free; LangSmith Developer: $0/seat/month plus usage; Team/Enterprise: See LangSmith pricing. Where exact limits or dollar amounts aren't published, check the vendor's site for current plans. That is especially important for procurement because usage-based credits, workflow executions, browser sessions, or tool execution meters can change the real monthly bill. A small pilot should measure the actual unit that drives cost: credits for coding, executions for integrations, traces/evals for agent platforms, or browser runtime for web automation.
