Path A · Publish an app

Free to publish. Your users pay in credits.

There is no fee to publish an app to Priostack's users. You decide what each capability costs in credits; Priostack meters usage, gets the user's consent, and bills them. You build the app - the platform runs the plumbing.

Publishing
Free
No listing fee, no seat fee. Ship model-only apps with no server, or bring your own backend.
Your users pay
In credits
You set a credit cost per capability. A user spends credits when they use your app - after they have granted it, at the autonomy they chose.
Priostack handles
The plumbing
Discovery, the consent prompts, metering and billing. You are not building an audience, a payments stack, or a permission UX from scratch.
Want to list on the Marketplace with a price, or talk revenue terms? Talk to us - we set listing terms with you rather than publishing a number we would have to caveat. No promises of an audience or a payout; what you get is the contract, the metering, and the consent model.

Pricing questions

What counts as one execution?

One execution = one process instance started via /api/v1/process-instances. Completing or cancelling the instance does not cost extra. DMN decision evaluations and CMMN case activations each count as one execution.

Can I run multiple client engagements on one plan?

Yes. One Priostack subscription covers all your client workspaces. You manage everything from one account - each client's data stays isolated but you are not charged per client.

What happens when I exceed my monthly quota?

Your account returns a 402 on new instance starts until the next monthly refresh or until you top up manually from the wallet. Existing running instances continue to completion.

Is there a per-seat fee?

No. All plans are per-subscription, not per-seat. Add team members and client contacts without paying more.

Can I cancel any time?

Yes. No minimum term, no cancellation fee. Your sandbox remains active on the free tier after cancellation.
