What you pay for

One step, one span.

Every model call, tool call and retrieval your agent makes is one span. A run with six steps is six spans, retries and failures included. That is the whole meter. No seats-times-features maze, no per-trace surprise.

Questions

Quick answers.

What is a span?

One recorded step in a run: a model call, a tool call, a retrieval. Plans are sized by spans per month.

Can I try it without paying?

Yes. The Free plan includes the trace viewer and cost visibility, and needs no card.

How does annual billing work?

Pick annual and every paid plan is 20% cheaper per month. You are billed once a year instead of monthly.

How do I start a paid plan?

Choose Pro or Team and you go to a short checkout page. Pick the project it should cover and continue to Stripe. Card details are handled by Stripe.

What can I send traces from?

The TypeScript and Python SDKs, OpenTelemetry, or plain HTTP.

Do you offer anything bigger than Team?

Enterprise adds custom spans and retention, SSO, on-prem deployment and rollout support. Talk to us and we will size it.
