Free for open source.
Fair for everyone else.
ticktrace is dual-licensed. Use it under the AGPL-3.0-or-later forever, no charge. If you can’t accept AGPL’s share-alike obligations — because you ship proprietary firmware, run a network service, or have a corporate policy — pick the commercial tier that matches your team size. Linear pricing as you grow; no SKU caps; no surprises.

Count the developers who touch the SDK. 1–5 → Indie ($199/yr flat). 6–10 → Team ($999/yr flat). 11+ → Professional ($999/seat/yr, linear). Need indemnification, safety artifacts, or a defined SLA at any team size? Enterprise.
Linearly, by design. Indie covers up to 5 seats for $199. Adding your 6th developer moves you to Team — flat $999/yr through 10 seats. Adding your 11th moves you to Professional, where every additional seat is $999. No jagged cliffs, no ‘contact sales’ surprises in the self-serve range.
Indie and Team are per company — flat fees covering a fixed seat budget plus unlimited products. Professional is per developer seat. All three self-serve tiers let you ship into any number of products / SKUs.
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.
