LangSmith is recommended for AI startups, global enterprises, and engineering teams who want to observe, evaluate, and deploy reliable agents at scale. Companies like Klarna, Elastic, and Rakuten use LangSmith to speed up tasks and improve agent performance.
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.
