Today, the most profound impact of the .io / GitHub marriage is educational. If you want to learn how to build a multiplayer game today, you do not buy a textbook. You go to GitHub.
To understand the symbiosis between .io games and GitHub, one must first understand the genre’s accidental origin story. In 2015, a developer named Matheus Valadares launched Agar.io . It was a simplistic concept: a petri dish where players controlled a cell, eating smaller cells to grow while avoiding larger ones. The domain extension for the British Indian Ocean Territory ( .io ) happened to be available, catchy, and associated with "Input/Output" in computer science—a perfect fit for tech-savvy gamers.
Developers face specific technical hurdles when hosting web games.

This is the world of .io games. And if the web browser is the console, then is the engine room, the publishing platform, and the infinite cheat code all rolled into one.
