Communication within the workplace isn't just board meetings anymore. It extends to conference calls, virtual meetings, and discussion threads. Teams today need the right platform for seamless business communication compared to slower alternatives such as email. 

Introduced in 2013, Slack provided a solution for workforces across the globe. It offered real-time communication, adding and editing files, and tagging co-workers in work threads and discussions. Regardless of where the employee worked, there was no lag in communication. Over time, it became one of the most well-known instant messaging platforms. 

Even today, Slack is a beloved and preferred solution by many business teams. But as teams diversified, they realized that Slack was no ‘one-glove-fits-all’ solution. By then, Slack competitors and open-source Slack alternatives had gained prominence in the field. They offered cheaper plans, new customized features, or ones that Slack lacked. 

12 best Slack competitors leading the way in 2022

Although Slack has quite the buzz in the industry, it’s not the perfect choice for every organization. For instance, Slack does not offer end-to-end encryption for all messages, and the free edition also supports a limited number of messages.

For companies in highly regulated industries, this might pose a challenge. We’ve reviewed the most popular Slack competitors and how they differ.

1. Rocket.Chat

Rocket.Chat is the most popular open source alternative to Slack

Deemed as one of the most secure instant messaging apps, Rocket.Chat can be hosted on-prem and customized to fit privacy and security standards in highly regulated industries. Its recent integration with Pexip widens the possibilities of secure on-premise collaboration by combining chat and video conferencing.

Rocket.Chat goes beyond Slack with its federation possibilities, i.e. the ability to interact with users from other platforms via Rocket.Chat.

2. MS Teams

Slack competitors

Microsoft Teams serves mostly enterprise companies. Recently, it replaced a retired on-prem version of Skype for business. Its unique feature is that it is a collaboration and communication app, compared to a primary chat application like Slack. 

The freemium version of MS Teams contains basic features and more, such as 250+ integrations. It includes in-built audio, video calls, and integrations. 

How does MS Teams differ from Slack?

4. Mattermost 

Slack competitors

Some Slack competitors seem to grasp the need for customization. And brands such as Rocket.Chat and Mattermost offer open-source platforms that allow private cloud hosting or a self-managed server.  

Mattermost supports over 600 integrations with plugins, bots, extensions, and others. This tool allows businesses to customize it according to their requirements. It’s mostly aimed at developers as an audience.

Slack competitors

One of Slack's competitors is Fleep, which is known for its unique features. Fleep organizes conversation histories by the user, rather than the channel. A pinboard tool on the side contains key pinned conversations, channels, users, and frequently used information.

What are the benefits of switching to a Slack alternative?

Essentially, many tools differ from Slack by compensating for some of its weaker or non-existing features. Some competitors provide increased storage, task management, and other in-built management tools.

A portion of Slack competitors is doubling down on security features

Self-managed hosting, not available with Slack that’s a cloud-based product, is an important feature for many businesses that care about its privacy. Open source code is another important feature for businesses in highly-regulated industries that want a higher level of customization and transparency in how their data is handled.

Another way in which Slack competitors differ from Slack is going beyond team-based comms, and offering communication with clients on their platforms.

Slack is still a very powerful solution with a broad audience, but it’s not a perfect solution for every company. Since instant messaging platforms are prerequisites in business today, organizations should carefully pick the tool they use.
