I started an experiment to let a WASM-powered webapp interact with a local git repo and see how well this works. It turns out, it works pretty well!I made it into a "git wrapped" tool that shows you when you committed the most, and what languages and files you most touched.Despite the scary prompt when you use the filesystem API everything happens locally and your code stays private. (You can of course also just try it on cloned public github repos).Let me know what you think!

Could you build this?
Partial While compiling libgit2 to WASM is largely off-the-shelf and the Svelte UI is straightforward, binding browser File System Access API streaming into Emscripten MEMFS efficiently requires non-trivial low-level glue code.
What it would actually take: The architecture combines a Svelte/Vite web application with a WebAssembly build of libgit2 via Emscripten, interfacing with local directories via the Chromium File System Access API. The tricky engineering hurdle is streaming directory blobs into Emscripten's virtual filesystem (MEMFS/IDBFS) without exhausting browser memory on multi-gigabyte repositories. It requires web platform proficiency and familiarity with C/WASM toolchains and browser file I/O.
