I’ve been using LangWatch Agent Simulations for a few months now, and it has truly transformed the way I approach AI testing. The platform’s open-source nature and focus on agentic testing make it a powerful tool for developers who treat AI like software. The simulations are robust and help catch regressions early, giving me confidence in deploying autonomous agents. What I appreciate most is the intuitive api and the awesome visualization, which streamlines the testing process. The community support and regular updates also demonstrate a strong commitment to improving the platform. Overall, LangWatch Agent Simulations is a must-have for anyone serious about AI development and quality assurance. It’s a game-changer in ensuring AI systems perform reliably in real-world scenarios.

We've used LangWatch for output monitoring and evaluation of our RAG application. I can't recommend it enough. We find value in iterative evaluation with tools like DSPy and RAGAS, to production optimization features like jailbreak detection + document & topic tracking, all with a great dashboard and UI. The team has built a great product. Plus the team is very responsive and helpful.

Helped me personally with my AI project. No More AI blackbox - powering decisions with insights. Helps to mitigate safety risks as well as to know where exactly the bot is hallucinating, therefore increases quality. Makes safe guarding it against malicious practices like jailbreaking possible. All in all, wonderful tool for anyone working with LLMs

I recently spun up LangWatch, Langfuse, Langsmith and Opik for a real comparison in our production environment and LangWatch was just such a pleasure to use. It just hits the mark on everything that I want a monitoring platform to have. I'm looking forward to the video showcasing my experience.
