Blur is an event-driven IRC-framework written in and for Ruby.

There are a bunch of other well-written, well-running IRC libraries made for Ruby, but for me, they don't quite cut it as the library I wanted to use for my IRC services. That's how Blur came to be.

Blur scales. A lot.

When I stresstested the library on my network, I ended up throttling my VDSL connection before Blur even broke a sweat - albeit I only have 20/2.

I managed to connect with 5000 clones before it couldn't resolve the hostname anymore, while this is an excellent feature, I would not suggest doing it.

Bitdeli Badge Build Status Dependency Status


  • SSL/TLS encryption
  • Connect to multiple networks
  • FiSH (channel-wide) encryptions
  • Non-blocking connections (no threading)
  • Extensible with scripts, (re)loadable during runtime
  • Modular, makes it a piece of cake to extend its IRC-capability

Future Plans

  • DCC File-transfers
  • DH1080 Key-Exchange
  • ISupport implementation
  • Better event-handling in scripts
