Mattermost is a secure, open source platform for communication, collaboration, and workflow orchestration across tools and teams.
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.

Whether you’re part of a school club, a gaming group, a worldwide art community, or just a handful of friends that want to spend time together, Discord makes it easy to talk every day and hang out more often.
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.
Great app that even supports video meetings
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 a group chat app in which messages are threaded by topic, helping you have long-running, organized conversations.
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.
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.

Matrix defines a set of open APIs for decentralised communication, suitable for securely publishing, persisting and subscribing to data over a global open federation of servers with no single point of control.
Matrix.org vs Slack opinions
It can be easily bridged to many other chat systems, including Slack, which makes transitioning much easier. It's also open source and decentralized (self-hostable + communication with other servers).
Respects your Freedom. Increasingly popular
somegirlfromitMatrix is a protocol, not a client.

AirSend vs Slack opinions
thiagoaoI think the combination of communication and task/file management makes Airsend an excellent tool. They are always including new features. Best of all it is Free.
Marco_RaterThe best feature here is the ability to add outside organisations. So you can get one airsend org to talk to another org. Which is really awesome
hazzelle721Collaboration is made easy
