Fair for everyone else.

// how self-serve works
From card swipe to signed license in minutes.
Click Subscribe on the tier that fits. Stripe Checkout collects your company name, contact email, and the name of the product you intend to ship.
On payment success, our Worker issues a unique license number, signs it with an Ed25519 key Amken LLC controls, and stores the certificate.
You receive the signed license certificate by email within minutes. Anyone can verify it at /license/verify with just the license ID.
Your subscription renews each year. Cancel any time; previously shipped firmware remains licensed for the version you shipped.
// frequently asked
If your organisation is under 10 staff and under US$1M revenue, the Indie tier is intended for you. Under 100 staff / US$10M, the Medium tier fits. Beyond that, or if you need indemnification / safety artifacts / a defined SLA, you need Enterprise.
Per company. One subscription covers your whole team and all of your products within the tier's eligibility bounds.
The right to incorporate ticktrace into proprietary firmware and proprietary services without AGPL source-disclosure obligations. The terms are the Master Commercial License Agreement that ships with your certificate.
Firmware you have already shipped under an active subscription stays licensed for the version of ticktrace you shipped. New versions and new products require a current subscription.
Yes. Stripe handles proration. Email us to switch tiers and the next license certificate reflects the change.
If you can ship under AGPL (your source is open, including any network-facing service) you do not need a commercial license. The Indie tier is for people who want to keep firmware proprietary.
AGPL itself works for evaluation: build, test, prototype, no charge. When you're ready to ship a closed-source product, that's when a commercial tier kicks in.
Open /license/verify and enter the license ID. The Worker returns the issued-to organisation, tier, and validity window. The Ed25519 signature in your certificate lets you verify offline against the public key published on this site.
