What is LangWatch?

LangWatch is the open-source LLMOps platform that helps teams collaboratively debug, analyze, and iterate on their LLM applications. All platform features are natively integrated to accelerate the development workflow. Building AI applications is hard. Developers spend weeks debugging issues, optimizing prompts, and ensuring quality. Without proper observability, you’re flying blind - you don’t know why your AI behaves the way it does, where it fails, or how to improve it. LangWatch provides the missing operations platform for AI applications. Every LLM call, tool usage, and user interaction is automatically tracked with detailed traces, spans, and metadata. See the full conversation flow, identify bottlenecks, and understand exactly how your AI applications behave in production.
