Features
x86-64 Playground is a web app for experimenting and learning x86-64 assembly.
The Playground web app provides an online code editor where you can write, compile, and share assembly code for a wide range of popular assemblers such as GNU As, Fasm and Nasm.
Unlike traditional onlide editors, this playground allows you to follow the execution of your program step by step, inspecting memory and registers of the running process from a GDB-like interface.
You can bring your own programs! Drag and drop into the app any x86-64-Linux static executable to run and debug it in the same sandboxed environment, without having to install anything.
Who is this for?
The app is for anyone that wants to run amd64 assembly snippets or inspect the inner workings of simple Linux ELF files.
It has been designed with the academic world of binary exploitation in mind; The debugger interface offers visualizations similar to the GDB+PwnGDB debugger plugin, and all the controls are labelled with the respective GDB commands.
Combined with Compiler Explorer, this app provides a noise-free environment to learn the basics behind the inner workings of a Linux process. When you are ready, it includes the guides and resources necessary to keep experimenting on your own linux environment, with the actual GDB debugger.
Designed for the web
Have you ever seen a responsive debugger? The app places the mobile experience at the center of its design, and can be embedded in any web page to add interactivity to technical tutorials or documentations.
Follow the guide to embed in your website both the asm editor and debugger.
Offline-first and open-source
The app is open-source, and available on Github. It's powered by the Blink Emulator, which emulates an x86-64-Linux environment entirely client side in your browser. This means that all the code you write, or the excutables you debug are never sent to the server.
everything runs in your browser, and once the Web App loads it will work without an internet connection.
