shelehovchanin Same functionality. Same interface. At the same time, there are much fewer restrictions. IN my experience, the free version is great enough for a team of 100 peopleIts 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 !it is similar in features, and has some more, for example XMPP compatibility (-> many more client choice) and ability to self host it! - Discord is about giving people the power to create belonging in their lives. We want to make it easier for you to talk regularly with the people you care about.

TheBeast Good app for your personal use. Wouldn't recommend for an Enterprise setting which is what Slack is more geared towards.jbrown Very 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.thompsonmj Slack 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. - A free instant messaging and collaboration software based on the Matrix protocol.

abijith Three reasons: 1. Open source. 2. Stream 3. TopicsZulip 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.paulocoghi More 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 - Rocket.Chat is a Web Chat Server, developed in JavaScript, using the Meteor fullstack framework.

JohnFastman Does 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.Rocket.Chat comes very close to slack regarding it's core features and handling.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...No screenshots yet

nejinv19 I have used Slack extensively, one thing I like very much about Airsend is the ability to manage files along with messaging.olgafedorova Free. Has all the messaging features. One on one messaging is a bit convoluted but overall it's greatkhart We are this app to collaborate with our remote marketing team. The best part of this app is it brings chat, files, tasks and notes in one space. We don't need to switch between multiple apps to complete the work. - Hangouts is a messaging app that lets you send and receive messages, photos and more, and even start free video and voice calls – one to one or with a group!
