Glitch Web Client

Glitch was a browser-based MMO created by Tiny Speck. This repository contains the source code for the game client.


All files are provided by Tiny Speck under the Creative Commons CC0 1.0 Universal License. This is a broadly permissive "No Rights Reserved" license — you may do what you please with what we've provided. Our intention is to dedicate these works to the public domain and make them freely available to all, without restriction.

All files are provided AS-IS. Tiny Speck cannot provide any support to help you bring these assets into your own projects. Many of these files are not structured in a standard, straightforward way, and they may take a bit of your time and work to understand.

Note: the Glitch logo and trademark are not among the things we are making available under this license. Only items in the files explicitly included herein are covered.

There is no obligation to link or credit the works, but if you do, please link to, our permanent "retirement" site for the game and these assets. Of course, links/shoutouts to Tiny Speck ( and/or Slack ( are appreciated.

What you'll find in here:

All of the source code for Glitch's Flash-based browser client.

What is not included

A working version of the game. :(

The Glitch client requires a Glitch server to work, and there are no longer any Glitch servers for it to use. This code is provided mainly for instructional and reference purposes; if you are attempting to develop something with any of the asset repositories, the client implementation may be a valuable resource.

Documentation Contributions Are Welcome!

If you figure something out that you think others could learn from, write up a quick how-to document and submit it to us as a pull request. Share your knowledge!
