How it’s built
- tree-sitter in WebAssemblyReal grammars for JavaScript, TypeScript, Python, Go, Rust, CSS and JSON, parsing in a pool of Web Workers off the main thread.
- Metrics from syntax treesCyclomatic complexity, nesting depth, function and import extraction come from the parse tree, not regexes.
- One instanced draw callThousands of buildings in a single three.js InstancedMesh, with a custom ray–box picker and a stable 60 fps target.
- Squarified treemap streetsDeterministic, unit-tested layout: footprint is lines of code, folders become districts with street gaps.
- 100% localFolders and zips are read in the tab. Nothing is uploaded, nothing is stored on a server.
