We love Open Source
Structr is an open-source project because we believe in the power of the community.
With Community, we mean the people who are interested in Structr, having fun building a great product together. We, the core team, made a start, releasing thousands of lines of code to the public.
Community means also give and take. You can use Structr for free, even in commercial projects, as long as you publish your source code under the same license as we did. If you can't disclose what you've built upon Structr, please ask us for a commercial license.
If you just use Structr for your own project, as a standalone software, not changing or re-using the source code in your own product, you can use it like you use MySQL or any other GPL-licensed CMS (most of them are GPL-licensed), free of charge and free of any other restrictions.
