Every plan includes full hash-chain integrity and the open-source verifier, identical on every tier. Paid plans add RFC 3161 trusted timestamps, shareable proof links and a live badge (Builder); then up to 10 team members with roles and SSO, data exports, and evidence packs mapped to EU AI Act Article 12 and HIPAA audit-control requirements (Team). Limits apply to the licensed build you run. We host no agent records. 14-day refund on paid plans.

What changes between tiers

The cryptography does not. Integrity, the chain and the verifier are the same code on every tier, including free. Paid tiers add external time, sharing and team scale.

Pricing questions

What counts as an event?
One record written into the chain. A tool call, a guardrail decision, a prompt, a completion, a redaction, a run boundary. A typical coding-agent run writes somewhere between 100 and 250 events, so 50k a month covers roughly 200 to 500 runs on the free plan.
What happens when I hit the limit?
Nothing is deleted and no record is dropped silently. Limits apply to the licensed build you run, and the CLI tells you when you are near the cap so you can upgrade or keep running self-hosted under the AGPL.
Does the free plan expire?
No. Free is free forever at 50k events a month. There is no trial clock and no card required to reach it.
Is the cryptography weaker on the free plan?
No. Hash-chain integrity, Ed25519 signatures and the open-source verifier are identical on every tier. Paid plans add RFC 3161 timestamps from an external time authority, which prevents back-dating; they do not make the chain itself any stronger.
Do you store my agent records?
No. Provenrail hosts identity and billing only. Agent records live in your own sink, on your own infrastructure. That is a deliberate design choice, and it is why the verifier runs entirely in your browser at provenrail.com/verify with no upload.
Can I self-host instead of paying?
Yes. The client, SDK, verifier and spec are MIT-licensed and the server is AGPL-3.0-or-later. Run the whole thing yourself at no cost. Paid plans exist for hosted convenience, external timestamps and team features, not to unlock the core.
How do refunds work?
14 days on paid plans, no questions. Billing runs through Polar as merchant of record, so cancellation and refunds are handled from the same portal you subscribed in.
Can I pay annually, or in euros?
Plans are billed monthly in US dollars today. If annual billing or another currency is a blocker for you, write to [email protected] and say so; that is the kind of request that decides what ships next.
