Frequently asked.
What counts as a trace?+
One end-to-end agent or prompt run. Internal LLM calls, tools, and queries within a single run all roll up into that one trace.
Bring my own LLM keys?+
Yes. Bring your own provider creds and we orchestrate them — your provider bills you. Or route through our gateway with usage on your plan.
Upgrade or downgrade anytime?+
Yes. Upgrades prorate immediately. Downgrades apply at the end of the current billing cycle.
What if I hit the cap?+
New traces pause until next cycle, or upgrade instantly. We never charge overages without an explicit plan change.
SSO / SAML?+
Yes — Enterprise includes SSO, SAML, custom guardrails, dedicated support, and custom SLAs.
Self-hosted?+
On-premise and VPC deployments under the Custom plan. Talk to sales for a scoped evaluation.
Is there a free plan?+
Yes. The Free plan includes 500 traces per month, 3 active agents, 1 data source, and community support — no credit card required.
Do you offer a trial for paid plans?+
The Free plan acts as an indefinite trial — every feature critical to evaluating PromptRails is available there. Paid tiers do not auto-enrol you in a trial; you only pay when you explicitly upgrade.
