Pricing for technical release control
One platform for policy gating, signed evidence, and non-Kubernetes release orchestration. Every tier includes full capabilities; pricing scales by environments and new-digest deep scans.
v1.0-RC1 is available now — signed public bundle and images, installed with one command. v1.0 is expected on 1 January 2027, and pre-orders are open.

Pre-order
Pre-order Plus and you are provisioned as Pro — the higher environment count, scan allowance, offline cadence and support level, at the Plus price. An early-adopter rate that ends at v1.0. RC1 is public today, so evaluate first.
Every capability ships in every tier, including compliance packs, and every tier allows unlimited deployment targets — there is no per-target charge. Tiers change capacity and support, never features. The Free tier permits limited production use; beyond its limits a paid plan (Plus or Pro) is required.
How metering works: an environment is a logical deployment boundary, and a new-digest deep scan is the first deep analysis of a unique image digest. Re-checking an already-seen digest consumes nothing. The Free tier meters over a rolling 24-hour window — 999 new-digest deep scans in any 24 hours, with no monthly pool; paid tiers meter per calendar month. Environments and new-digest deep scans are the only metering axes: deployment targets are never metered, on any tier. These limits are terms of the licence, not runtime restrictions in the software — nothing stops at the cap; the free grant is what the terms permit.
Annual billing option: pay for 11 months, receive 12 months of service. Capacity add-on on any paid tier: +10,000 new-digest deep scans for $399. Prices are shown excluding VAT; any applicable VAT or sales tax is determined and charged at checkout by our merchant of record, based on your location and tax status.
Free and Plus are self-serve: documentation and guides, community discussions and Doctor self-diagnostics, with no contractual response target. Pro files tickets through an email support channel at a 1-business-day response target, and also includes everything in self-serve. Enterprise: Support, response, and onboarding terms negotiated per contract.
