Text reviewers explain a diff line by line. Architectural damage lives between files: a dependency that breaks a layering rule, a class that quietly grew five methods, a module boundary that is no longer there.
Archscape reads a repository at two states, draws every class of it as a Card on one Diagram, and paints the change onto it — which classes and methods were touched, what new dependencies appeared, and which of the repository's own rules they broke. Seventeen languages, no compiler needed.
This page is the demo. It reads any public GitHub repository as it stands, or any commit or Range you pick from the header. Your own code goes nowhere: the repository you name is cloned in a disposable container, read there, and the reading is what reaches this page.
A pre-release, built by one developer. There is a desktop window and a VS Code extension behind this page. Tell me anything — palm1r-github-dev@pm.me.
