Mattermost - An Opensource Slack Alternative | First Look

You’ve always heard of Slack and might be using it in your daily work life. But, have you wondered that there is an opensource slack alternative is available?

Yes! you heard it right.

An Opensource Slack Alternative is available which has all the features of slack and few additional features as well. You can secure your business communication data using this opensource slack alternative.

Mattermost – An Opensource Slack alternative?

Mattermost is a sleek, private cloud and opensource slack alternative that makes it easy to self-host the teams communications. It brings messaging and file sharing  into one place, accessible across different systems and mobiles, with support of archiving and advanced search. Also, it integrates with a range of apps out-of-the-box.

Let me brief you few details about me and how Mattermost comes to rescue.

I am a technical guy, basically a nerd who loves to code on WordPress and research on new tech tools that can simplify our lives.

I’ve been using Slack for more than 2 years or so. But, researching on Slack in detail gave me an idea that using additional features will require additional bucks to spend.

Even, If I pay $6.67/month/user or I kept on using the free plan with restrictions, then Slack will be annoying me for each small thing whether it is upload limits or restriction of users. 🙁

Mattermost is at rescue when it comes to speak about Slack alternative or I would say “Mattermost is a Slack restrictions alternative” 🙂
