Introduction
Lunary describes itself as the AI platform for enterprises and an observability and prompt management platform for LLM-based apps. It shows how LLMs perform in real time and how users interact with chatbots, internal tools and customer-facing assistants.
Teams use it to monitor usage and improve from real feedback, closing the gap between a chatbot and its users.
Teams evaluating Lunary should decide early whether to self-host or use the cloud, because that choice shapes data retention and compliance reviews. Start by tracing one feature end to end, then add datasets and evaluations once you can see which conversations are failing and how often.
Keep the first rollout small: one feature, one dashboard and a weekly review of the worst-rated conversations.
Features
- Real-time monitoring: LLM performance and usage.
- Conversation insight: How users interact with bots.
- Prompt management: Version prompts.
- Feedback: Learn from user signals.
Pros
- Simple pricing: Per-user monthly price.
Cons
- Payment required: Workspaces need payment to activate.
- Lighter eval tooling: Less testing depth than eval platforms.
Usage and Links (Example)
- Create a workspace and add the SDK.
- Watch conversations and feedback in the dashboard.
- Iterate on prompts from the observed failures.
