Mattermost vs Slack opinions
Its the same but you keep your server where you want so no one is playing with your data, and you can have an unlimited history depending on what you need for free so really way better !
Mattermost is quite versatile and has been used within several of my past employers.
liger1978Great interface, you control your data.
It's faster for one thing. It's far superior in terms of data ownership, and it's extremely scalable.
svelleHas more flexibility due to its extensive plugin system compared to other alternatives.
MudieLooks and works very much the same as Slack and complete control over your data housed separately from anyone else.
jaydelandOpen source with control over your data.

Features
Discord vs Slack opinions
TheBeastGood app for your personal use. Wouldn't recommend for an Enterprise setting which is what Slack is more geared towards.
zetneteorkDiscord is a good choice for communities with various interests. There are nice options on how to sort topics into individual channels. I do not see Discord as a competitor of Slack in the business sector.
alexandrezanniDiscord is more gamer oriented than business oriented.
leylineDiscord is much simpler to use in terms of connecting new servers/workspaces to your account, but slack has conversation threads which sometimes come in handy if a conversation is between 2 people but wants to stay in the main channel so others can reference it. 95% i would choose discord though.
DillxnDiscord is now rebranding to be more enterprise-friendly. It can be customised to fit your every need.
jbrownVery very similar in terms of use and features. Of course, discord is marketed as for gamers while slack is for teams but usage is almost identical.
thompsonmjSlack is a project productivity and communication enhancement tool with integrating with other collaborative tools like GitHub, document editors, storage, etc. Discord is for recreational chatting.

Zulip is the only modern team chat app that is designed for both live and asynchronous conversations. Zulip topics create a separate space for each discussion, so different conversations will never get in each other's way.
Features
Zulip vs Slack opinions
the threading model is the best i've used for keeping up with active communities, and the open-source community is excellent.
It's a little different, for sure, but what it does, it does better than slack. Not a open source copy of slack like mattermost. If you want slack and nothing else, but in open source, stick to mattermost, if you want something that exceeds that, choose zulip.
paulocoghiMore than feature parity with Slack, it's better because of Streams and Topics. It offer the same free tier with 10.000 max messages and better paid plans to the hosted version, and also provide the open source self-hosted option to install it on your own server and also remove the max messages limits. 5 stars
The concept of topics to each message is a super useful feature :)
Zulip is open source and the methods of communications used is vastly different. It is specially useful in professional environments where different teams might want to participate in different conversations at the same time. Zulip solves this problem by including topics, where in each channel/stream, multiple topics can exist at once, at the same time.
superbicheOpen Source without limitations when on premises. Much better information categorisation with Streams & Topics. Vibrant community.
shantnukumarOne can easily switch in between conversation between different threads! Extremely helpful for any organisation.

Rocket.Chat is a Web Chat Server, developed in JavaScript, using the Meteor fullstack framework.
Features
Rocket.Chat vs Slack opinions
Rocket.Chat comes very close to slack regarding it's core features and handling.
JohnFastmanDoes everything Slack does AND it's open source. However, it's also self-hosted. This means you have to put in the effort to set it up, but you control your own data, which is a huge advantage to your privacy - your chats and files don't sit on someone else's servers, ready for them or hackers to look at.
open source, locally hosted so you own your data.
