The 10 Best Slack Apps (Free and Premium)

Joe Martin

Slack has revolutionized how we communicate in business. From quick notes about a product launch to sharing a story about your dog, it has found a way to connect the ever growing Gig Economy of remote workers as well as those who sit next to you. Did you know it can get even better with apps?

Good, because the Slack apps we list in this post will only add to the emoji level excitement you get every time you get a new Slack notification.

Its true, Slack is outstanding on its own, but there’s plenty of features users wish they had that Slack hasn’t been able to get to for users.

And there’s no way they could’ve packed in every app without losing the ability to focus on its core offering.

Lucky for you, not all of the Slack apps you’ll read about today require a subscription.

That’s not to say you should only look for free Slack apps. Some of the premium Slack apps are so worth the investment, you’ll want to get a subscription today if you’re serious about taking your Slack game to the next level.

But before we get into the free and premium Slack apps, let’s quickly go over how to discover and install Slack plugins with instructions provided from Slack.com.

Explore the Slack App Directory (From Slack)


The App Directory lists every app, add-on, or plugin that can be integrated with Slack. No matter what your area or specialty, there’s an app, add-on, or plugin to help make your work more pleasant, productive, and hopefully fun! Check out the Slack App Directory and start browsing.

Browsing Tips for Slack Apps (From Slack)
