What Lunary is

Lunary is an AI platform for developers building chatbots and other LLM-powered applications, as well as enterprise teams. It monitors and helps debug model calls and agents through traces, error views, search, and filters. Analytics track model usage and costs, frequent topics, user satisfaction, and custom dashboards. Teams can create and collaborate on prompt templates, manage versions, and run A/B tests. They can also arrange human reviews and score model responses. Listed integrations include Anthropic, LangChain, OpenRouter, IBM WatsonX, Gemini, AWS Bedrock, and OpenAI; several other integrations are marked as coming soon. Lunary is available on the web, through an API, and as a self-hosted deployment. The Team plan costs $20 a month, billed monthly at $20 per user per month, and includes 50,000 events and 300 AI Playground queries monthly. Extra events and Playground queries are billed separately. Existing Free workspaces remain available. Lunary says its cloud data is encrypted in transit and at rest, and Lunary Cloud is not suitable for HIPAA-compliant data collection.
