Eight loops for the day a code host or a build pipeline goes down: GitHub Wildfire, GitHub On Fire, GitHub Boom, Unicorn Mitosis, Unicorn Shake, GitHub Old Man Yells, Unicorn Laser Eyes and Unicorn Glitchy. They are short animations of a burning, shaking or glitching logo or pink unicorn, so a channel can say the thing is broken without writing it out.
On Fire and Wildfire are for an outage that is spreading, Boom is for a failure that happened all at once, and Glitchy and Shake suit a service that is up but wrong. Old Man Yells is for the person who found out first. Mitosis and Laser Eyes are the lighter ones for the follow-up thread, once the incident is under control.
These are reaction images for workspaces, not official assets. We cannot confirm any link between them and GitHub or its mascot, and we do not claim one. We cannot confirm who made these images, so if you made or own one and want it removed, the contact page will get it taken down. Our suggestion is to keep a pair of them, such as On Fire and Shake, in the incident channel only, so they stay meaningful.
Download any emoji above, then upload it as a custom emoji in your workspace. Step-by-step guides: add custom emojis in Microsoft Teams, add custom emojis in Slack, or add custom emojis in Discord. These eight files are 112 by 112 pixel animated GIFs, about 15 to 55 KB each. That is under the 128 KB Slack's help recommends and the 256 KB figures Teams and Discord list (checked October 14, 2026). Your workspace can still restrict who may add emoji. Discord's help says uploading needs the server owner or the Manage Emojis or Create Expressions permission, and its custom emoji page also covers animated emoji, so check it for what your account and server allow.
