What is Lunary?
Lunary records what LLM apps and chatbots do in production, so teams can trace requests, review conversations and manage prompts in one place. It is aimed at companies shipping AI agents and assistants, and the platform can be self-hosted from its open-source code.
Logs and events feed chatbot analytics that show how users talk to your app and where answers fall short. Prompts are versioned centrally, human reviewers can grade outputs, topics group conversations, and an AI playground lets you test prompts against models.
The Team plan includes a set number of events and playground queries each month with overage pricing beyond that, plus full API access, custom dashboards and CSV or JSONL exports. Enterprise adds custom terms for larger organizations.
