What IRC client do you use?

I'm using thelounge (https://thelounge.chat/).

It runs in a container, and I can keep a tab open on my phone, my work laptop and my private laptop without much hassle.

I've used irssi (https://irssi.org) for years.

Have a session running on a shell host under tmux. Works perfectly for me on a desktop and a mobile ssh client.

I use a IRC client that I wrote many years ago, in PHP (which isn't the programming language I would use if I were to redo it today), on Windows, with PuTTY as the terminal emulator; I still use the same program, but now on Linux, with xterm as the terminal emulator.

I go through several "suckless" type IRC clients - currently my own patched version of: https://c9x.me/irc/ - which is nice and simple.

weechat (https://weechat.org/)

It's available on the SDF metaarray and looks really good in a terminal, so it's what I use.

Hexchat for Windows

erc, bundled with Emacs

irssi forever

Facebook messenger

Slack (it's not exactly IRC, but move on with the times)
