Known Shorteners Database

The dataset behind Link Expander is community-maintained on GitHub: DontPokeMe/known-link-shorteners. It's free to use via our API, and anyone can help keep it current.

What's in it
  • Shorteners — URL shortening services (bit.ly, tinyurl.com, etc.)
  • Redirectors — link redirect/processing services
  • Tracking — known tracking and analytics link domains

Link Expander only follows redirects through domains in this dataset — see a domain it didn't recognize? Submit it below.
