Open-source engineering calculators for civil and structural design
Structural, geotechnical, tunnelling and contractor tools available free and open source on GitHub.
Searchable construction datasets covering high-rise buildings, bridges, tunnels, dams and housing.
Registered users get calculation workings, bending/shear/deflection diagrams and PDF export.
Four project-based pathways in Python, AI for construction, AI governance and building AI agents.
Web data API that turns any site into clean, AI-ready content
Multiple endpoints cover discovery, single-page extraction, whole-site crawling, and URL mapping from one API.
Returns Markdown, structured JSON, HTML, links, and screenshots while stripping navigation, ads, and footers to cut token usage.
After scraping, drive clicks, typing, scrolling, and navigation with prompts or code to reach data behind interaction.
Python and Node SDKs, REST API, CLI, and an MCP server let agents and IDEs connect in minutes.
