@dbdiff/cli distributes a platform-native self-contained binary — a static PHP interpreter with all required extensions baked in, combined with the DBDiff PHAR. There is no PHP installation, no Composer, and no runtime dependencies required on the end-user machine.

npm automatically downloads only the binary for your platform (~10–15 MB):
