x86-64 playground: an online assembly editor and GDB-like debugger
http://x64.halb.it:

1. The app is for anyone that wants to run amd64 assembly snippets or inspect the inner workings of simple Linux ELF files.
2. Combined with Compiler Explorer, this app provides a noise-free environment to learn the basics behind the inner workings of a Linux process.
3. 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.
