Teams that need quick member checks without installing desktop software often open CalcForge in the browser. The vendor groups free structural calculators (beams, 2D frames, trusses, steel and concrete section helpers) on calcforge.com alongside broader geotech and contractor tools.
Pricing on calcforge.com shows a Free plan at US$0 with limited engineering tools and dataset access, plus a Lifetime All-Access tier sold as a one-time payment (US$75.00 on the pricing page checked 10 November 2026). Paid access adds training qualifications, the full pre-built tool library, datasets, and code repositories per the same page.
