7 Free Slack Alternatives You Will Love
Whatsapp Pinterest

Slack has rapidly risen to the top of the online communication platform pile. The instant messaging-cum-team workspace has won many major customers since its 2013 arrival. Slack’s success is built upon a simple understanding — life is all about communication. And email is no longer appropriate for fast-paced working environments.

That isn’t to say there is no place for email The Odd Story of How Email Became So Damn Popular The Odd Story of How Email Became So Damn Popular Email seems like such a primitive bit of technology. How did it ever become so popular? And how come we still use it to this day? Here's the story of how it all happened. Read More .

Here at MakeUseOf, we have a paid Slack subscription. This means we have unlimited members, channels, integrations (extra services you can plug into Slack), and more. But there is an unlimited free option that’s limited to a 10,000 message archive (believe me, that can disappear extremely quickly!) and just 10 integrations.

If you have a smaller team or limited budget, we’ve got a list of seven Slack alternatives you’ll want to check out.

1. Rocket Chat

Rocket Chat is an open source Slack alternative. This means the chat client is completely customizable if your programming skills are up to scratch. Rocket Chat is a resolute experience out-of-the-box. It offers many features that free and paid Slack versions doesn’t have:

  • Audio and video conferences.
  • Integrated live-chat for websites.
  • Screen sharing.
  • Theming, branding, and white label installation packages.

Rocket Chat has an intuitive UI, which further exemplifies the easy experience on this chat platform.

You can use Rocket Chat on Windows, Mac, Linux, iOS, and Android.

2. Ryver

Ryver grants your team a completely free chat platform experience. While Ryver isn’t open source, it does offer free unlimited chat storage, data, guests, posts, search, teams, and users. That’s a lot to pack in. Better still, Ryver isn’t underhanded with its free offering — your weekly team brief won’t be interrupted by a terribly targeted, seizure-inducing flashing advert.

No, Ryver has taken a firm aim at Slack’s free version. By offering threaded posts as well as the some premium Slack features, Ryver will certainly pull people in.

You can use Ryver on Windows, Mac, Linux, iOS, and Android.

3. Bitrix24

I think Bitrix24 is a perfect Slack alternative for busy teams seeking to integrate project management into their chat client. Often cited as one of the best free project management tools 7+ Best Free Tools to Manage any Project with Ease 7+ Best Free Tools to Manage any Project with Ease Collaborating on projects is much easier with the Internet.

5. Fleep

Fleep! Sorry, it just sounds good. Go ahead: say it out loud.

Now that is taken care of, I can introduce you to a messaging client with a focus on team integration. Fleep does something differently to Slack. While Slack is excellent for chatting with a single team at a time, Fleep lets you reach out and chat to other organizations without leaving the client. Furthermore, it brings those stubborn, email wielding individuals into the fore. So long as you have an email address, Fleep will bring the conversation to you.

Your team can use Fleep’s unlimited message history, unlimited conversations, and unlimited integrations, as well as up to 5 GB file sharing per user.

You can use Fleep on Windows, Mac, iOS, and Android. A Linux client is planned.

6. HipChat

HipChat offers “team chat that’s actually built for business.” That means your team can make use of unlimited and persistent messages, integrated ticket tracking for website and service support, screen sharing and group video chat, along with access to over 200 integrations.

HipChat consistently achieves top scores and glowing reviews. The sheer range of integrations, along with premium Slack features means HipChat could become your team command center. Another major bonus is HipChat’s simple integration with other Atlassian developed tools. If you already use Atlassian products, such as JIRA Service Desk, or Bitbucket, HipChat could be a useful team tool.

You can use HipChat on Windows, Mac, Linux, iOS, and Android.

7. Mattermost

We round-off our Slack alternatives with open source chat client Mattermost. Mattermost are competing with Slack. As such, you’ll find a number of premium Slack features available to your team for free.

Other extremely useful features include threaded messaging, a single account for multiple teams, customizable themes, syntax highlighting for programmers 8 of the Best Free Collaborative Tools For Programmers 8 of the Best Free Collaborative Tools For Programmers If you're a programmer and you aren't yet sharing or collaborating, you're behind the curve.

Slack is excellent. It is.

    You need to take off Ryver, or at least modify the description. They announced today that they will only offer free accounts for up to 6 users... $99/month...

    Contus Fly is a pre-built chat api for mobile app that gives enterprises total control in terms of app management as well as backend customizations. From code to cloud hosting, the entire control of the messaging sdk and chat api remains vested with the buyer enterprise.

    In the future, as and when more refinements in terms of design or functionalities are required, it can be carried out by hiring a developer either from Contus or from their own sources.

      Sorry you're horribly childish. Cum is latin for "with," but has been bastardised over the years to mean semen. Grow up.

    Hey! Great article. ...just to add, I have been using Flock which is a free communication app for teams providing direct and group messaging with the ability to create public and private channels. It is available in English, Spanish, Portuguese, and Russian.

    To add to that, its free and offers integrations with 40+ third party apps including Google Drive, Github, Trello and many others and provides a set of business apps including Shared To-dos, Reminders, Polls, Note Sharing, Code Snippet Sharing and so on.

    You say it's free, then the first review you give is for a paid service, which I find out 10 seconds or so in to your review. So yeah. It's really irritating when people are misleading.

    Slack also has a free option, so what's the point of using a lesser alternative that's not that much cheaper, and certainly not free!?

    • Gavin Phillips
      April 13, 2017 at 11:57 pm

      Whoah there. Rocket Chat is free if you download and host it yourself. It also has a lot of options not available in the free version of Slack.

      There are also 6 other options to choose from that offer varying degrees of integration and customisation. Did you look at them?

      What's your chat tool now?
