CIRC: An IRC Client for Google Chrome

Powerful Packaged App Offers Chrome Users IRC Tool

Been looking for a Google Chrome IRC Client? You’re finally in luck.

CIRC (Chrome IRC) is a IRC app for Chrome, Chromium and ChromeOS that lets you connect to and chat with people on IRC.


CIRC In Action – Not an Extension, Or a Web App

But what’s most interesting about the tool is that it’s not an extension or a web-app; CIRC is a ‘Chrome Packaged App’.

Packaged Apps are able to do things web-based apps can’t, including accessing parts of your computer, like network and hardware devices, media tools, etc.

Because of this additional support packaged apps are able to look and work like traditional native system apps – despite being written in the same technologies as web apps.

Features include:

  • DIrect connection IRC servers
  • Servers, Channels & Nicks saved and synced across Chrome instances (so no need to set-up again)
  • Allows for simultaneous IRC connections on multiple devices (like Google talk)
  • Scipt Support & Syncing
  • Desktop notifications

For Chromebook users in particular CIRC is a must have as it’s the only non-web-based solution available. It integrates deeply into the ChromeOS desktop, with its notifications looking particularly swish in the ChromeOS Dev channel:

CIRC isn’t the most user-friendly of IRC applications. There are not shortcut buttons or menu entries to perform common commands.

Instead everything from joining a channel to leaving one is done using the standard IRC commands.

The most common ones you’ll need are:

  • /server <server url> Connect to a server
  • /join #channelname – Join a channel
  • /nick <name> – Changes nickname
  • /part – Leaves channel entered in
  • /partall – Leaves all channels
  • /quit – Quits all servers and channels

    Errrr… SSL?

  • Is that the Roboto font I see being used in the app?! Seems like a merge of Chrome OS and Android isn’t too far away after all…

    Just installed this new app on my Chromebook, I love it. Nothing like having that native app feeling. Now I wish someone would write an app for the terminal that feels native as well, so I can ssh into my servers without using an extra tab on my browser.

  • Pretty sweet project! <3

  • Does it allows to download files or it’s chat only yet?

    • David Li

      No DCC support; only chat one year later.

    I didn’t quite catch, if I can run it as a tab in Chrome browser. That’s the whole point, for me. >.>
