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.
Open-source control plane for orchestrating coding agents
Run Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok sessions side by side in one workspace.
No resold tokens or quota caps — connect the credentials and plans you already pay for, and switch models mid-thread.
Manage branches, automate commits and pushes, and handle pull requests with inline diff review before accepting changes.
Open-source and MIT licensed, so you can run it on your own infrastructure and modify it for your team.
Offers an integrated AI-native code editor experience rather than a standalone multi-agent orchestration control plane.
