The 10 Best Slack Alternatives

Slack has been quite prominent in the project management space for a while.

That is not to say Slack is the only service out there that.

Before we jump to the alternatives to Slack, let’s look at the reasons why you might have started using Slack.

What is Slack?

Slack is an instant-messaging platform that runs on the cloud and allows for its users to be able to send and receive messages right from within the app. What helps is the fact that Slack allows for many other existing services to be integrated into it and vice-versa.

slack platforms

This means that you can receive your e-mails, files, messages, notifications, and others right from within Slack. Think of it as an aggregator of different services that also provides its own messaging service.

Everything is put under either channels (group messages) or direct messages (DMs). This makes it much easier to keep you and share stuff since it is all under one roof.

Knowing what brought you to Slack will help you hone in on the things to look out for in the alternatives that we have listed next.

Now, let’s move onto –

The 10 alternatives to Slack that might fit your needs the best.

RocketChat allows for easy migration from other services such as Slack – all that you got to do is to export your files from Slack and upload it to RocketChat and you’re all good to go. RocketChat is great in terms of the features it offers; they are quite similar to Slack’s offerings –

Google Hangouts

Google Hangouts for businesses is currently split into two services under the G Suite – Hangouts Meet (Calls & Conferencing) and Hangouts Chats (Instant Messaging). It allows for instant messaging, sharing of files and voice/video-conferencing with anybody from the inside or outside your team/organization.

While Google Hangouts is free for regular consumers, businesses and teams have a lot to gain by signing up for Google’s G Suite (starts at around $6/month/user) –

G-Suite users get access to lot more features on Hangouts than the free users –

  • Up to 25 members per call (30 for G Suite Enterprise users) and the ability to call into meetings with a dial-in number
  • Allows for screen-sharing to present documents, spreadsheets, or presentations
  • Encrypts all data being sent
  • Can enable real-time, AI-generated closed captioning while on calls

With Hangouts being a Google product, it integrates well with the plethora of Google services – Gmail, Analytics, Docs, Sheets, Google Drive and such – very well. It allows for the creation of groups but not the creations of specific channels as in the case of Slack.


Chanty is a simple team chat tool that is more suitable for small and medium-sized teams and businesses.

Chanty, unlike Slack, also automatically organizes all your files, tasks, links, and conversations into folders in a feature called Teambook.

Discord is a voice and text chat that was actually built for gamers since the other service that was on offer had a lot of hassle in terms of setting up or were quite costly. Discord is so well-built that it is being used by many as yet another team/project management app.

You can replicate the public and private channels of Slack quite easily on Discord using its own public and private channel settings. Best of all – Discord is free. Also, Discord’s paid offering (Nitro) provides you with nothing but improved aesthetics and gaming-related features – none of which help boost productivity in any way.

Discord also offers push-to-talk which could be handy in case your team or business can utilize and benefit from it.

But with Discord not being built for team/project management, it does not allow for integrations with external apps and services quite easily – especially the productivity-based services.
