Why flat pricing
Cost and subscription fatigue are the most-cited pain points among small structural firms — most of the profession runs on 1–20 seat offices that still lean on spreadsheets. StructuralClaw is priced so a sole practitioner doesn't have to think about it: one flat rate, every module, and the free browser tools stay free.
When can I actually buy it?
When the desktop app ships. Billing is deliberately not live yet — we won't take money for software you can't download. Join the launch list and you'll get one email when it's available, with the trial ready to go.
What does the 7-day trial include?
The full app — every module, printing included. No feature-crippled demo tier.
Is my project data sent to a cloud?
No. The desktop app runs offline; project files are local files on your machine, in a documented JSON format you can read yourself.
Is there an online version?
Planned — individual modules exposed in the browser with code-cited PDF output. In development; accounts and online pricing are not live. The free tools are available today.
Will the price change?
This is planned launch pricing. If it moves before launch, this page moves with it — we won't advertise one number and charge another.
