Who is Lunary best for?

Customer-facing chatbots
Chat replays, feedback tracking and topic classification show where a bot lets users down.
Agent builders
Agent tracing and a one-line integration log each step an agent takes, so errors surface early.
Prompt management
Prompt templates, an AI Playground and human reviews let a team test and score prompt changes in one place.
