11 Best Slack Alternatives To Try In 2023 | Free & Paid

The Slack collaboration tool needs no introduction. Your team may be one of its millions of users. However, despite its many useful and powerful features to increase productivity, the platform has some flaws. For example, Slack is cloud-based, with servers located in the United States. Unable to host sensitive data about your business yourself. It poses a security problem. In addition, not all small businesses have the means for the paid version of the application (which can be useful, especially for backing up conversations).

Why Look for an Alternative to Slack?

After a remarkable release and a complicated progression due to various problems encountered, such as a computer hack that caused a leak of user data, the company has improved its security system and implemented two-factor authentication. It ended up finding its cruising speed and experienced an extraordinary evolution: 6 million users in 2017 used this collaborative solution every day.

However, the substantial increase makes users fear that other hacking attempts will take place, and this will jeopardize the company due to data theft. This is the first reason why some want to find an alternative to Slack. On the other hand, the Slack software server is based in the United States. It is a problem for some companies that want to host sensitive data.

Slack's Strengths and Weaknesses Slack is here to make your daily tasks easier. By giving you the possibility to connect to many services such as Google Drive, Office 365, and others, this collaborative platform allows you to free yourself from certain constraints of repetitive tasks such as communication or anything that can be automated. Slack allows you to collaborate in channels in unlimited numbers.

By ensuring better coordination between efforts, we can be faster in decision-making. Slack has all the tools you need right at your fingertips. In addition, your messages are stored in archives. There are plenty of reasons to find alternatives to Slack. Indeed, this platform has some weaknesses that it is good to know before making your choice.

Its main weakness is that companies cannot host their data on their personal server. Indeed, Slack uses the Amazon server. In itself, this is not necessarily a problem except for companies who fear for some of their data.

Another element that can make management complicated is that users have control over the establishment of channels. Indeed, if everyone adds channels, it then takes too much time to monitor everything and be up to date with the actions of your employees.

Slack has another drawback, that of not being able to block a user. As it is a collaborative work tool, the goal is to be able to contact its collaborators. It can sometimes lead to negative things like bullying. Fortunately, there are equally good and sometimes free alternatives. Discover our 11 alternatives to Slack!
