Review

LangWatch is a powerful platform for teams building AI agents, offering end-to-end evaluation, testing, and monitoring rather than focusing solely on individual LLM responses. Its open-core approach and the Scenario framework make it especially useful for simulating realistic agent workflows and identifying issues before deployment. While the platform is geared more toward developers and may have a learning curve for beginners, it provides valuable observability and evaluation capabilities for production-grade AI systems.
