Our verdict on Lunary
Lunary is an LLM observability platform for AI developers, startups, and enterprise teams building internal tools, chatbots, and autonomous agents. It records LLM calls and detailed agent traces, supports evaluations and model benchmarks, and brings prompt management, human reviews, cost analytics, replay, and feedback tracking into one workspace. Teams can access it through the web or API, while organizations that need more data control can deploy it self-hosted.
Pricing is straightforward for smaller teams. The Team plan costs $20 per user per month and includes 50,000 events per month, 300 AI Playground queries per month, unlimited projects, one year of history, prompt management, and human reviews. Enterprise adds self-hosting, SSO, granular access control, PII masking, SLA coverage, and white labeling. The product also supports CI/CD evaluation integration, prompt versioning, testing, deployment, and rollback, making it relevant beyond runtime monitoring. New cloud workspaces are positioned around paid Team or custom Enterprise plans, while the Community Edition can be self-hosted for free.
Its ecosystem covers OpenAI, Anthropic, LangChain, LangGraph, OpenRouter, IBM WatsonX, Mistral, Grok, Fireworks AI, Gemini, and AWS Bedrock, along with Ragas, Power BI, Tableau, and MySQL. That breadth suits teams working across models, frameworks, analytics tools, and data systems. Lunary is a strong fit for small teams that want tracing, evaluations, prompt workflows, and cost visibility without assembling separate tools. Larger organizations can choose Enterprise for identity, access, privacy, and deployment controls. Teams that require verified retrieval tracing or a no-cost cloud workspace should compare alternatives.
