Included
What you get
The project canvas, about 70 calculators and viewers for steel, concrete, wood, masonry and foundations, drawing and PDF intake, and saved designs. Your files stay on your machine.
Closed beta
What the beta is, and what it is not.
An invited group testing an agentic engineering workspace on Windows, macOS and Linux. Free for 14 days, the whole workspace with nothing held back, and direct access to the person building it. Read what is still rough before you install.
Windows, macOS and LinuxFree during betaLicence key required
Platform
Windows, macOS and Linux
Windows 10 or 11, macOS 12 or newer, and Linux as an AppImage or a .deb. Same build, same tools on all three. There is no mobile or browser version.
First run
The Windows installer is unsigned
Windows shows "Windows protected your PC". Choose More info, then Run anyway. The Mac build is signed by Apple and opens normally. On Linux, mark the AppImage executable.
Licence
Activate once, online
Paste the licence key from your approval email the first time you open the app. After that it runs offline for 30 days.
Licence
A seat runs 14 days
When it runs out the AI agent panel and the terminal stop. The calculators, the canvas, the drawing tools and export keep working, and your files stay on your disk. We email you before the date and say whether the beta is being extended.
AI
AI needs your own key
The agent panel runs on your Claude Code or Codex CLI login, or your own Anthropic API key. CoLateral supplies no model credits. Everything else works without one.
Requirements
The agent terminal needs Node.js
Node.js on your PATH, for the terminal only. Without it the terminal does nothing. The engineering tools do not need it.
Updates
Updates are manual
New builds are announced by email and installed over your existing copy.
Offline
Two tools use the internet
The climatic tools load their map from a public service and tell you when it is unavailable. Everything else runs from files that ship with the app.
Feedback
What we want from you
Which tool you opened first, what you expected it to do, and where it did not match how you work. More useful than a list of bugs.
Bug reports
Reporting a problem
Send your operating system, the version from the About box, and the steps that led to it. Never include confidential project data.
Privacy
Your data stays yours
Everything is stored and calculated on your machine. The privacy policy says what is and is not collected.
Responsibility
Engineer review is still required
Every calculator is a design aid. CoLateral does not certify or stamp anything, and no output should leave your office without engineer review.
