AI agent testing platform that ensures reliability through simulations.
LangWatch is a platform for AI agent testing and evaluation. It transforms unpredictable agents into reliable systems through simulations, continuous testing, and comprehensive observability It combines essential features with an intuitive interface to deliver measurable results.
LangWatch does not help with AI visibility. Instead, it focuses on transforming unpredictable AI agents into reliable systems through simulations and continuous testing. By enabling users to write scenarios in Claude Code, it allows for precise behavior testing in plain language. This supports stronger discoverability over time.
