The toolkit spans structural analysis (beam, frame, truss, steel and concrete section design), geotechnical work (bearing capacity, slope stability, retaining walls, foundation settlement), tunnelling, and contractor tools such as formwork, scaffolding and slope grading. It also ships curated construction datasets covering high-rise buildings, bridges, tunnels, dams and housing. The free tier gives registered users full calculation workings, bending/shear/deflection diagrams and PDF export, while the one-time Lifetime All-Access pass unlocks advanced calculators, code templates and enrolment in four training qualifications. The project grew out of Civils.ai and is supported by an active Discord community of around 1,500 engineers across 30+ countries. Because the tools are open source on GitHub, engineers can fork the code, add their own calculators and send pull requests back to the main project. CalcForge positions itself as a way to democratise engineering knowledge and to help professionals automate the most time-consuming parts of their work. **Pricing & Plans:** Free account with core engineering tools and datasets; one-time Lifetime All-Access payment unlocks 32+ advanced calculators, 10,000+ construction datasets, code repositories and four training qualifications. - **50+ open-source calculators:** Structural, geotechnical, tunnelling and contractor tools available free and open source on GitHub. - **Datasets for benchmarking:** Searchable construction datasets covering high-rise buildings, bridges, tunnels, dams and housing. - **Full workings and diagrams:** Registered users get calculation workings, bending/shear/deflection diagrams and PDF export. - **Professional certifications:** Four project-based pathways in Python, AI for construction, AI governance and building AI agents. - **Community collaboration:** A Discord community of 1,500+ engineers sharing calculators, ideas and contributions. **Strengths:** Genuinely free and open source for the core calculator library; Broad coverage from structural analysis to tunnelling and contractor tools; Rare combination of tooling plus structured training certifications; Active community and transparent GitHub contributions **Limitations:** Advanced calculators and datasets sit behind the paid lifetime pass; Code snippets and some datasets are not available on the free tier; Advanced training materials are geared to construction rather than general software fields [Profile (Markdown)](https://openaitools.app/tool/calcforge.md) ## Frequently Asked Questions ### How do Brevo and CalcForge compare in monthly traffic?
