One rate card. Every feature, every plan.
Plans differ by how many traces you send per month. They don't differ by what you can do with them.
- The full call tree — nested prompt, retriever, model call, tool, and answer
- Per-node latency, token count, and cost
- Full input and output for every node
- Redact sensitive fields in the SDK, before anything leaves your machine
- Python and TypeScript SDKs, plus the REST API
- The web dashboard, where each trace opens as a call tree
All of this is on Free too.

Straight answers on cost and growth.
What happens when I go over my plan's volume?
Your traces keep arriving, and we add $1 per additional 100,000 traces that month. Nothing pauses.
Are any features held back on the Free plan?
No. Free has every feature; only the monthly trace volume differs.
Can I move down to a smaller plan, or cancel?
Yes. Change or cancel anytime — it takes effect at your next billing cycle.
Are there hidden fees or add-ons?
No. You pay for trace volume and any overage; there's no separate charge for analysis features.
Do I need a credit card to start?
No. The Free plan starts with an email and a password, and it doesn't expire. You get an API key in about a minute.
