Hub Studio

Themes, animated scenes, a pet cat, code fonts and file icons for GitHub. Make GitHub yours.

Make GitHub yours. Hub Studio restyles all of GitHub (pages, code, graphs and menus) with one click from your toolbar. NEW IN V2 🐈 A PET CAT A real orange cat that lives along the bottom of GitHub. It wanders, naps, stretches, grooms, swats at your cursor, and now and then knocks something off the page (it floats back a few seconds later). Click it to pet it. Turn it on with "Pet cat" in the popup. 📊 THEMED CONTRIBUTION GRAPH Your contribution graph drawn in your theme's own shapes, glowing on your busiest days. EVERYTHING ELSE 🎨 THEMES Dark and light color themes that recolor every part of GitHub, including syntax highlighting and the contribution graph. Every theme is contrast-checked so text stays readable. ✨ ANIMATED SCENES Backgrounds that move behind your code: glowing eyes that blink in the dark, a 4K video of fire and violet light, anime eyes with falling sakura petals, and drifting color behind frosted glass. A strength slider goes from subtle to bold. 🎬 YOUR OWN VIDEO Drop in any video, GIF or image, up to 4K, and it loops behind every GitHub page. Your files stay in your browser and are never uploaded. 🔤 CODE FONTS Choose from 11 popular coding fonts, with ligatures on or off. Some fonts write your comments in a handwritten, cursive style. 📁 FILE ICONS Over 1,200 colorful icons for files and folders in repositories, so you can spot each file type at a glance. 🎉 CELEBRATIONS Confetti when your pull request merges, when all checks pass, or when you star a repo. Optional sounds. 📊 STATS, ONE HOVER AWAY A small tab on the edge of GitHub shows your streak, contributions, best day and top languages. Make a share card image in one click. 🧘 FOCUS MODE One tap in the popup (or a keyboard shortcut) pauses scenes, confetti, the cat and the stats tab when you need to concentrate. 🔒 PRIVATE BY DESIGN No accounts, no tracking, no analytics. Hub Studio only runs on github.com and only talks to GitHub. Have an idea? Use "Suggest a feature" in the popup. Hub Studio is free; if you enjoy it, the Support button helps keep it growing. Hub Studio is not affiliated with or endorsed by GitHub.
