Pricing

Free while you are looking. Paid when it has to hold up.

Every plan computes real evidence. Certificates come from registered designs — frozen before the data arrives — and that review is what you pay for.

A monitor is one task suite on one schedule. A check is one complete observation of that suite. We meter what you watch rather than how much telemetry you send, so the bill does not move when your traffic does.

02 The line

Anyone can compute an e-value. Only a registered design can be certified.

Evidence

Available on every plan, including free. Send scores or let us run checks; the estimator accumulates evidence you can read at any moment without invalidating it, and alarms when it passes your level. What it will not do is tell an outsider that the rules were fixed in advance — because on this tier they were not.

Included from $0

Certificates

On a registered design, the panel, the floor and α are reviewed and frozen before the first observation. That is what makes the published error rates apply to your monitor, and what lets a certificate be handed to someone who was not in the room.

03 Questions

Straight answers.

What exactly is a certificate?

A signed, canonical JSON file holding the frozen design, every block of evidence, and the result. You verify it offline; it replays bit-exactly or it fails. Verify one in your browser.

What does a certificate not do?

It does not certify the independence premise from your data. It attests the computation conditional on that premise, and says so on its face.

Can I self-host?

The Rust core is Apache-2.0. Self-hosted deployments come with the Registered tier; the public crate release is on the roadmap (see the record for the date).

Why no SOC 2 badge?

We are a design-partner-stage company and will not buy a badge before it means something. Your scores live in one Postgres instance, encrypted at rest; the full data-practices page says exactly what we store. SOC 2 lands when the first ten teams need it.

What happens to my scores if I leave?

Export everything via the API, then we delete on request. The public record never contains your data.

04 Get started

Two monitors free, forever.

We are onboarding design partners by hand. Tell us the task and we come back with a configured monitor, not a demo call.
