Lunary

Lunary belongs in the catalog because it captures a very practical segment of the AI tooling market: teams that want observability, prompt management, and evaluation workflows for LLM apps, but do not necessarily want a heavy enterprise platform on day one. The official product story is clear about observability, prompt management, self-hosting, and developer-first integration. That makes Lunary especially relevant for startups and product teams that want to operationalize LLM quality without committing immediately to a large enterprise contract.

It also deserves inclusion because the pricing is refreshingly clear. Lunary publicly lists Free at $0, Team at $20 per user per month, and Enterprise custom pricing, plus concrete event overage pricing and AI Playground query pricing. That level of detail is exactly what helps buyers evaluate whether the platform fits their scale now instead of guessing what happens after a trial ends.
