Is OpenLLMetry worth the price?
OpenLLMetry offers a generous "Free Forever" tier with up to 50K spans/month, which is excellent for small projects and individual developers.
The "Enterprise" tier is custom-priced, which is standard for larger organizations but lacks transparency for budgeting. This pricing model is best for early-stage LLM projects and enterprises needing tailored observability solutions.
Hidden Costs & Gotchas
No clear pricing for exceeding 50K spans/month on free tier.
Potential for high costs in Enterprise for custom retention.
