LangWatch: LLM observability and analytics platform for monitoring AI agent quality, costs, and user experience with real-time dashboards and automated guardrails.
LangWatch is an observability and analytics platform designed for monitoring LLM applications and AI agents in production. It provides real-time visibility into agent performance, quality, costs, and user experience through comprehensive tracing, automated evaluations, and customizable dashboards. The platform helps teams ensure their agents maintain quality standards while optimizing costs and identifying issues before they impact users.
The platform captures detailed traces of every agent interaction including prompts, completions, tool calls, retrieval steps, and metadata. These traces are automatically evaluated against configurable quality checks — sentiment analysis, PII detection, topic adherence, toxicity filtering, and custom business rules. Failed checks can trigger alerts, block responses, or flag interactions for human review.
