A unit is one trace or one observation, the same idea Langfuse bills on. We include more at every price point.
Every plan includes an AI analyst that investigates your traces on its own. Higher plans get more hours and a tighter cadence.
| Plan | What it does | Hours / mo | Like hiring |
|---|---|---|---|
| Starter | Weekly autopilot: surfaces new failure clusters, regressions, and cost spikes | 5 hrs | ~$500 of analyst time |
| Pro | Daily analyst plus on-demand deep investigations whenever you need them | 50 hrs | ~$5,000 of analyst time |
| Enterprise | Always-on, near-real-time monitoring that opens investigations as issues emerge | Continuous | A full-time analyst |
A unit is a single trace or a single observation, which is a span, event, or generation. Each one counts once, no matter its size or token count.
Hours the AI analyst spends investigating your data on its own: clustering failures, finding regressions, surfacing cost spikes, and writing up what it finds. 5 hours is a weekly review. 50 hours is roughly a daily analyst.
We price at the same points and include far more volume at each one, plus an AI analyst and autonomous investigation Langfuse does not offer. A unit means the same thing it does there.
We notify you as you approach your limit and help you move to the plan that fits. We never drop your data.
