## Requirements & limits

- Use the hosted interface or run a local instance with Node.js and configured compiler binaries. The pinned checkout’s .node-version is 22.23.4; the README accepts that version or newer and documents make-based setup.
- The tool compiles supplied source for comparison; it does not recover source from an arbitrary binary. The hosted compiler inventory and a local instance’s configured compilers can differ.
