Premise of the Hackathon

The TwitchCon Hackathon is a unique experience where we bring together our streaming  and developer communities. Partnered streamers will provide a list of interactive concepts they would like to solve with Twitch Extensions to ultimately provide a better experience for their audience.  For this hackathon, your team will select one of these Extension concepts and use that selection to drive the innovation of your project.

Every accepted participant of the hackathon receives a complimentary 3-day pass to TwitchCon.


Extensions are interactive web apps that enhance how viewers and streamers interact with each other in real time. Create interactive experiences that include mini-games, leaderboards, live in-game information, and more. You now have the power to truly impact the streaming experience on Twitch.

Rules at a Glance

All participants must be at least 18 years of age.

All participants must be legal residents of the United States, United Kingdom, or Canada.

Teams must be no more than four members and can be formed before or at the start of the event.

Each participant may only work on one project.

A project may not have any code dedicated to it until hacking begins on the Saturday of the event. Setting up your development environment with SDKs in advance is fine (and recommended).

Projects must be Twitch Extensions and must be built as close to the chosen Extension concept as possible.

Projects must be submitted by the time hacking ends on the Sunday of the event. After that, presentation materials may be worked on but no more design/development can be done on the submission.

Submissions will be judged on creativity, utility, presentation, and that special “Twitch” factor.

Winners will receive trophies, blog recognition, and be featured in the Extensions manager for broadcasters should the project be released for general availability.
