Kororin

A browser extension that takes you to a random active GitHub repo. Built for people new to GitHub — including non-coders.

Modes

• 🍀 I'm Feeling Lucky — anywhere on GitHub (active repos only)
• ✏️ Words — docs, typos, translations, awesome lists
• 🌱 Beginner code — repos with good-first-issue labels
• 🔧 Deeper code — repos asking for help past the first PR

When you land on a repo, a small card shows what kind of project it is and a 🎲 Try another button.
