Git.io API

Free to Use Varies (check documentation)

Overview

Git.io is GitHub's own URL shortener service specifically designed for shortening GitHub URLs into compact git.io links. It requires no API key and works with a simple POST request, making it trivial to integrate. Note that Git.io only works with GitHub URLs (github.com domain), so it is not a general-purpose shortener.

💡

Beginner Tip

Git.io only shortens URLs from the github.com domain: if you submit any other URL it will return an error. Use it in your GitHub-related tools or scripts to create cleaner links to repositories, commits, or pull requests.
