I've given up entirely on the Slack desktop app and use Ripcord exclusively. Much faster, more responsive and easier to use for 99% of my time spent on slack.
So Ripcord is making money on illegal thing? Discord / Slack ToS forbids third party app afaik. Edit: Why am I being downvoted? https://old.reddit.com/r/discordapp/comments/8tukek/ripcord_...
https://api.slack.com/community
we find
"terminal-slack - Terminal client for Slack"
"Slacker - Simple Slack client for the CLI"
"scudcloud - Ubuntu client for Slack"
I'm pretty sure there are others in that list which are also standalone thirdparty clients, but clearly they would not be listing those on their own site and providing plenty of API docs if they forbid them.
