Every time someone ask this question I think people are forgetting that Slack was the first of these SaaS chat programs to find major success. Discord, Teams, and everything else came riding on the heels of Slack's success. While it might just be "another chat app" now, at the time Slack was an easy to setup tool with tons of integrations.

And before Slack, HipChat was quite good.

Before HipChat was Skype-for-Business...uh... Lync... uh... Office Communications Server... uh... Exchange Server Instant Messaging (using Windows XP’s Windows Messenger) back in 2001!

So good that Atlassian sold it.

I used the Hipchat web client for a year. It worked perfectly.

I heard from others that the native app didn't.

I had a chance to talk to one of the Hipchat PMs. Atlassian didn't seem too attached to operating it for some reason.
