What you get, every time
Owned, not rented
Pay once and it's yours — a perpetual license. All FIRDesign 1.x updates are free; future major versions (2.0+) are optional, discounted for owners; never a subscription.
No subscription, no account
Nothing recurring to cancel and no sign-up. You just buy and use it.
Offline activation
Activate with a license key on your own machine — no login, no server, no phone-home.
Try before you buy
Run the free trial with every feature working except project save and impulse export, so you know exactly what you're getting.
Free 1.x updates
Improvements and fixes across the whole 1.x line cost nothing.
Fair upgrades
When 2.0 lands, owners get it at roughly half price — never a surprise.
