How many users can use the same board in a free version

[Julia Mariuska Hodgins]

We are a volunteer-based community with groups across countries. About 100 users in total. No one funds us and we want to use Free verson of Trello, is that possible?

[Cody Curry]

Absolutely! You could definitely use the Free version to collaborate with your colleagues.

Trello boards are organized into Workspaces, which can be thought of as a container for boards. Our Free Workspaces allow you to have 10 open boards within that Workspace at any given time.

If you need more than 10 boards, you could create a second Workspace for that, if you like!

We also offer a discount for paid plans if you're a qualifying charitable non-profit and you find that you want to give one of our paid plans a go: https://www.atlassian.com/software/views/community-license-request
