Try `autumn` — it's slow, it's insecure, and it's feature-incomplete.\n\nWebAssembly interpreter that fits in a QR code, taking 2945 bytes:\n\n![QR code](autumn.png)\n\nThis is a static x86-64 Linux executable. Scan the QR code with `zbarimg --raw -Sbinary` or another QR decoder that supports binary data, or [directly download the program](https://github.com/purplesyringa/autumn/raw/refs/heads/master/autumn). Run it with `./autumn \u003cpath to wasm file\u003e`. Example programs: [a guessing game](https://github.com/purplesyringa/autumn/raw/refs/heads/master/tests/guessing-game/guessing-game.wasm) and [QuickJS](https://github.com/quickjs-ng/quickjs/releases/download/v0.14.0/qjs-wasi.wasm).\n\nHow this works: [a blog post](https://purplesyringa.moe/blog/this-wasm-interpreter-fits-in-a-qr-code/).\n\nSince compilers are finicky, there's a nix package for reproducibility.\n\nThere are at least three dozen intended CVEs in this project. It is licensed under AGPL to motivate you not to run it in prod.\n\n\n## 📁 Project Structure\n\n```\nautumn/\n└── interp.c\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpurplesyringa%2Fautumn","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpurplesyringa%2Fautumn","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpurplesyringa%2Fautumn/lists"}
