Slack Alternatives: 10 Best Tools for Team Communication

Team communications are an essential part of any enterprise and we all know that Emails have become more about messages from machines rather than people. The point is, Email, during its prime, was all about messages from people at work and family. Now our inboxes are cluttered with automated emails, newsletters, and social media updates. That’s why using Emails for team communications might not always yield better productivity and there are by far better solutions for team communication. Slack, launched in 2013 by the founder of Flickr, is one of the most widely talked about and used team communications app right now.

Slack offers a better and easy way to communicate internally with your team and features a better search API that lets you search whole conversations based on context. Integration with many third-party applications like Google Docs, Dropbox, GitHub, ZenDesk and more is another one of the key features that Slack has to offer.

Why The Need for Slack Alternative?

While there are many upsides to Slack, it is not flawless. For example, while Slack offers a great free plan, it limits the context searching feature by doing away with the logs after it reaches 10,000 messages. It might also be the case that Slack doesn’t fit your team because of the work you do. And some users might find its premium pricing a bit costly. The truth is that no single team communications app can satisfy the needs of all the consumers and that’s why there’s a need for alternative team communication tools.

10 Best Slack Alternatives for Team Communication

Well, if you are one such enterprise looking to make the jump from Emails to a new platform for your Team Communications, here are the 10 Best Slack Alternatives that you can check out in 2020.

1. Hangouts Chat and Hangouts Meet

Hangouts Chat and Hangouts Meet are the new team conversation tools that are replacing “Google Hangouts” for G Suite consumers. While Google hasn’t had a good history with messaging apps, when it comes to team communications, its offering is quite solid. The best part about Hangouts Chat and Hangouts Meet is that they are free to use if you are a G Suite customer. And, if you are running a business, there’s a high chance that you are already using G Suite as the primary email provider. That means you will be able to use these excellent communication tools for free.

Hangouts Chat is for written team communications where team members can message each other to converse, just like they can do on Slack. Since Hangouts Chat seamlessly connects with other Google services, you can easily share files using Google Drive, work and collaborate on Google Docs, Sheets, or Slides, and use Google’s powerful search for finding shared files, past messages, and more. If you need to have a face to face conversation, then you can use Hangouts Meet to start a team video call. This is a boon for teams that work remotely. Once you consider all its features and essentially free price, you get a communications suite that can easily replace Slack for you.

7. Mattermost

One of the biggest problems with Slack is that it doesn’t offer any way to host it on your own company’s server. That might be a deal-breaker for many companies who deal with sensitive data and want to keep everything in-house. Well, if that’s what you or your business requires then you should check out Mattermost. It is an open-source communication tool for businesses that want to run it on their private servers. This allows companies to keep full ownership of their data and protect it behind their firewall and VPN.

    To work in a team, you really need to choose a user-friendly and reliable application. I can also add the Utopia p2p I think it is also a worthy alternative to Slack, which is also an all-in-one tool and guarantees complete anonymity and security of business data. Plus, it’s completely free. And this is one of the significant advantages, especially for a large team. Currently available in the desktop version for all software.

    • XxxXXyal says:

      Oh, cool. Since the beginning of 2021, my colleagues and I have decided to use this application for corporate communication. And I would like to point out the exceptional convenience of the ecosystem. Also, for the entire time of using this application, we never had to enter our personal data.

    • Vellania says:

      Really? Is this app completely free or did you mean the trial period? It looks like an overly tempting offer – an app that allows you to work remotely and keep in touch with your team. If it still really guarantees data security, I’ll install it today.
