Assess all options when looking for the best Slack alternative

Despite being a popular tool for facilitating team conversations, Slack has its limitations, such as minimum file storage and overwhelming notifications. Therefore, it is always good to know about certain Slack alternatives that offer a free version.

If you need an affordable, easy-to-use product with unique messaging features for smaller teams, you can consider Google Chat. The application offers some advanced features, such as Smart Reply for an enhanced user experience. If you are already using multiple Google applications, you can also try Google Meet to drive communication via online meetings and share documents. Google Meet and Google Chat not only help you with your basic communication needs but are also free for Google workspace users.

In case you frequently need to connect via face-to-face meetings, you can consider Zoom Meetings as a Slack alternative. The platform supports video calling and web conferencing for quick video interactions and provides other major collaboration features, such as screen sharing and private meeting rooms.

If you are more focused on the task and project management side of things, Asana and Basecamp can be good Slack alternatives. Other than providing you with ways for communication, both these tools also allow you to assign, manage, and measure the progress of tasks. You can even consider Trello, for that matter. Besides communication, the software can also be used to organize tasks and work on larger files as compared to Slack.
