No lock-in: the core is MIT, so your code keeps working even if we disappear. The license is verified in the browser and never phones home — if it lapses, nothing breaks; you just stop getting updates.
A key, support, and a year of releases
No calls to schedule and no onboarding programme — you buy a license and the library is already everything on this page.
Your key, by email
Email us and the license key for your domain arrives within one business day. No portal, no seat provisioning, no sales sequence.
Priority email support
Stuck on an indicator, a theme token, or a locale? Email support with a 48-hour response while your license is active.
12 months of updates
Every release for a year — new indicators, components and fixes. If the license lapses, the version you have keeps working.

No hidden tiers, no per-seat math. The free core is honest; Pro is everything we make.
