Lunary

Lunary is an observability and prompt management platform that tracks performance, costs, and user interactions for LLM-based applications.

Lunary provides tools for developers and product teams to monitor, test, and improve AI applications. Users can track model usage, analyze costs, and gain insights into user interactions through chat replays and topic classification. The platform supports prompt management, allowing teams to version, test, and iterate on templates collaboratively. It includes features for debugging LLM agents, such as trace logging and error stack analysis. Lunary is designed to be enterprise-ready with SOC 2 Type II and ISO 27001 certifications, and it supports self-hosting in virtual private clouds using Kubernetes or Docker.
