What a credit is
Every plan is measured in credits. Three rules cover how they are spent.
One credit, one run
A credit is spent when one persona finishes one run of one scenario. Re-running a test spends one more.
3 personas × 1 scenario3 credits
Personas cost nothing
Creating, editing and reusing personas never spends a credit, on any plan. Only a run does.
Create, edit, reuse0 credits
Credits reset, they don't stack
At the start of each billing period your balance is set back to your plan's allowance.
Unused at period endNot carried over
Plans side by side

FAQ
Billing questions
One credit is one persona finishing one run. Sending three personas through the same scenario spends three credits, and re-running a test spends one more.
Testing across a whole team?
Enterprise is priced per seat and scoped with us: credits per seat, longer history and as many personas as the work needs.
