Opsmeter combines endpoint, user, model, and prompt-version cost attribution in one view, so teams can quickly see what changed and why AI spend increased. It is provider-agnostic and built to keep telemetry reliable without breaking production flows.

Why should a person choose your product over its competitors?

Opsmeter's answer

Choose Opsmeter for faster root-cause analysis, simple provider-agnostic ingest, and practical budget/rate-limit handling. It helps teams act on cost spikes quickly instead of only showing high-level usage charts.

How would you describe the primary audience of your product?

Opsmeter's answer

Opsmeter is built for teams running AI in production: CTOs/engineering leads, platform and ops teams, and founders who need clear cost visibility and governance.

What's the story behind your product?

Opsmeter's answer
