Make a trace understandable to the team
Lunary reconciles messages with agent and LLM runs, and captures custom events and feedback. Traceloop also supports conversation sessions. Compare both with the same multi-turn issue and the people who actually review customer complaints.
Compare the integration your app needs
Lunary records feedback against a message or run. Traceloop documents annotation tasks with entities and tags, submitted through Python or TypeScript. Test the path from an in-app reaction to a reviewer finding the affected interaction.
Review the next version before rollout
Lunary provides shared drafts and a playground for model or custom-endpoint testing. Traceloop’s registry supports draft prompts and staged environment deployment. Pick the review and release process your team can apply consistently.
