Get startedWe're working on creating a detailed video review for LangChain.
LangChain is recommended for developers, engineering teams, and enterprises that want to build agents with open source frameworks and run, improve, and govern them in production. Companies like Klarna, Monday Service, Podium, C.H. Robinson, and ServiceNow use LangChain's LangSmith platform to run and improve their agents in production.
LangSmith offers three pricing plans: Developer (free with 1 seat and 5,000 traces/month), Plus ($39/seat/month with up to 10 seats, 10,000 traces/month, and 1 free dev deployment), and Enterprise (custom pricing with advanced hosting and support). Traces beyond the included amounts are billed at $0.50 per 1,000 base traces, with options for extended retention at higher costs. Deployment usage on Plus includes additional charges for extra agent runs and uptime, while Enterprise supports custom seats, workspaces, and hosting options like hybrid or self-hosted.
