Finally, professional structural engineering tools that don't require a corporate budget.|
Trusted by engineers designing with international standards
For too long, structural engineering software has been behind paywalls that most engineers and firms can't justify.
Expensive licenses
$3,000–$15,000/year for a single seat. Many engineers simply can't afford it.
Workarounds and compromises
When software is inaccessible, engineers find alternatives. Outdated versions. Unofficial sources. No updates, no security, no support.
Locked to a desktop
Install on one machine, tied to one OS. Work from a different computer? Start over.
Weeks to learn
Traditional software requires extensive training before you can be productive.
Start free, scale affordably
Full editor at $0. Pro features from $9/mo. No five-figure invoices.
100% legitimate, always current
Regular updates, full support, clean licensing. Engineering deserves proper tools.
