LangWatch provides real-time monitoring and quality assurance for LLM applications in production. Trace-level debugging captures complete execution flows with inputs, outputs, and metadata.
Automated quality checks run custom evaluators on every interaction — measuring relevancy, toxicity, PII exposure, and custom metrics. Alerts trigger when quality metrics degrade below thresholds.
Topic clustering automatically groups user queries by intent, revealing usage patterns and identifying gaps in application coverage. User feedback tracking correlates explicit ratings with quality metrics.
Open-source with self-hosted deployment. Cloud version adds managed infrastructure, collaboration features, and advanced analytics.
