Run, learn, and debug x86-64 Assembly code directly from your browser
I recently created this project to teach assembly, and to have an assembly playground in the style of codepen/jsfiddle to embed in my blog posts. It's based on a wasm version of the blink x86-64 emulator, so everything runs client side with no backend server and with a runtime of only ~200Kb
In plain words
This is a browser-based x86-64 assembly playground that allows users to write, run, and debug assembly code directly in their browser. Built on a WebAssembly version of the Blink emulator, it requires no backend server and runs entirely client-side with a minimal ~200KB footprint. The tool is designed for teaching assembly and can be embedded in blog posts, functioning similarly to code-sharing platforms like CodePen or JSFiddle.
