Welcome to Coolr!

Coolr is a simple, open-source, ephemeral group chat built on Nostr.

  • Connect using your favorite Nostr extension or go anon 👤
  • Join or create public channels using hashtags (e.g. #21m).
  • Supports Bitchat geohash channels! No special bc_ needed.
  • All messages are ephemeral (temporary), you only see messages if you are connected.
  • Open source: GitHub
  • Use /help for a list of commands.

If you want to login with your nostr key you need to install a Nostr browser extension like Alby or Nos2x.
