Simple, usage-based pricing.
Starter starts with a 30-day free trial; Growth and Business bill immediately at signup with no trial. Every plan is a monthly plan with an included credit allowance, and you pay a metered overage rate only if you go beyond it. No per-seat pricing, no sales call required to get started.

How credits work
Every API call that generates data draws on your monthly credit allowance. Not all functions cost the same to serve: simple, in-memory functions — generating a random name, formatting a number, and similar — are lightweight and cheap. Functions that rely on durable, cross-call state, like sequence counters (createSeq/getSeq) or relational batch context (getContext), are more resource-intensive, since they require a database round trip to stay consistent across calls.
Usage is measured in a single unit — credits — that already accounts for this difference, so your bill reflects what you actually use rather than a flat per-call rate. See the Function Reference for the cost tier of every built-in function.
How overage works
If you use more than your plan’s included credit allowance in a billing period, the extra usage is billed at your plan’s overage rate, calculated automatically from your metered usage and added to your invoice for that period. There’s nothing to configure — overage billing is automatic and transparent, and you can review your usage at any time through your account. If you’re on Starter’s 30-day free trial, you have full access to Starter’s included credits at no charge, with no overage billed until the trial converts to a paid subscription. Growth and Business are billed immediately at signup, with no trial, so overage billing applies from day one on those plans.
Refunds & cancellation
- Canceling during Starter’s 30-day trial means you are never charged — no card charge happens for a canceled trial. Growth and Business have no trial and are billed immediately at signup.
- Refunds for the most recent billing period are considered case-by-case at our discretion when usage was light that period. There is no published numeric threshold for this — it is intentionally discretionary.
- Only the base plan/subscription fee is eligible for such a refund; metered usage-based overage charges are never refundable, since they reflect consumption already delivered.
- Separately, and unconditionally: new subscribers have a 14-day cancellation/withdrawal right under EU consumer law. This is a guaranteed legal right, distinct from the discretionary refund policy above.

Frequently asked questions
Only Starter has a free trial — Growth and Business bill immediately at signup with no trial. For Starter, a valid payment method is required at signup, but you are not charged during the 30-day trial. If you don’t cancel before the trial ends, your card is automatically charged the Starter monthly rate on day 31, and normal metered billing begins from there.
Usage beyond your included monthly credits is billed automatically at your plan’s overage rate and added to your next invoice — there’s nothing to configure. On Growth and Business this applies from day one, since those plans are billed immediately with no trial. On Starter, this applies once your trial has converted to a paid subscription; during the trial itself you have full access to Starter’s included credits at no charge.
Yes. Moving to a higher tier lowers your per-credit overage rate, so consistently heavy usage is generally cheaper on a higher plan than paying overage on a lower one. Contact us or use your account settings to change tiers.
Enterprise plans are arranged directly with custom pricing, custom service terms, and dedicated support — typically for teams that need a dedicated VPC or cluster deployment, a custom SLA, or an annual commit. Contact us at [email protected] to set one up.
Every API call that generates data draws on your monthly credit allowance. Simple, in-memory functions (like a random name or a formatted number) cost very little; functions that rely on durable, cross-call state — like sequence counters or relational batch context — cost more, since they require a database round trip. Concretely: by default, most lightweight functions (random names, emails, numbers, dates, formatting, etc.) currently cost 10 weight-units each, and a single credit is 1,000,000 weight-units — so one credit covers roughly 100,000 of those calls. Stateful functions like sequence counters (createSeq/getSeq) or relational batch context (getContext) currently cost more, 1,000 weight-units each, or about 1,000 calls per credit. A typical template mixing both easily produces tens of thousands of generated documents from a single credit. These per-function weights are admin-configurable and may be retuned over time — see the Function Reference for the current per-function cost tier of every built-in function.
