What makes HeySpace a great Slack alternative?

Channels vs. workspaces

Teamwork in Slack happens in channels – that’s where team members contribute to conversations or upload files. In HeySpace, you create workspaces that offer more functions thanSlack’s channels. Apart from a place for communication, workspaces are also platforms for task management, where tasks are organized on boards.

The task management feature

HeySpace allows you to organize tasks in a Kanban board, which gives you a clear overview of your team’s work. You can assign tasks to particular members of your workspace, set due dates, monitor progress, add checklists, tags and estimates, as well as attachments – either from your computer or from Google Drive. Simply drag and drop your files to cards. Each task card has its own chat, where you can discuss related matters, ask questions or inform of any important updates. Additionally useful might be the function of creating tasks from messages in private or group chats with just one click. Task management has never been easier! And you can access your tasks everywhere thanks to our mobile apps. On top of that HeySpace is easy to use and doesn't require long training.

File storage

Slack’s free plan offers 5 GB of file storage in total, while the premium plan – 10 GB per member. It seems a lot, but what if we told you that you can get unlimited file storage? Because you actually do! HeySpace offers unlimited file storage in both plans, so you no longer need to worry about losing important data.

The price

Last but not least – the price. Slack offers a free basic plan which can meet the requirements of a small team, and so does HeySpace. Free version is limited to up to 10 team members and includes only basic features like chat and  board for task management. The difference is in the price of the premium plans, as you can benefit from HeySpace premium features for just $5 per user / month, while Slack comes to $8 per user / month if billed monthly. To put it simply, you get more for less! Yoy can test our Premium Plan in 14-day free trial. No credit card required!
