Get the free FIRDesign trial

Install once and run every feature — project save and impulse export are shown but locked until you activate. Self-contained: a trimmed runtime is bundled, so there is nothing else to install.

System requirements

FIRDesign is self-contained: each installer bundles a trimmed OpenJDK and OpenJFX runtime, so there is nothing else to install and no separate Java required.

  • macOS — Apple Silicon or Intel Mac
  • Windows — 64-bit Windows
  • Linux — 64-bit, arm64 or x86_64

First launch

Code signing arrives in a later release, so macOS and Windows may show a routine "unidentified developer" prompt the first time:

  • macOS — right-click the app → Open.
  • Windows — choose More info → Run anyway.

How to activate

The trial unlocks everything except project save and impulse export. To unlock the full version:

  1. Buy FIRDesign — a one-time $39 purchase. Buy now →
  2. Get your key by email — you'll receive a license key (and a key file) right after purchase.
  3. Open Activate… in the app and paste your key (or load the file you were sent). Activation is fully offline.
  4. Restart FIRDesign — everything unlocks, and your copy is "Licensed to you".
