Composite C1 is Free Open Source

When you install Composite C1 you get unprincipled software - it is not a "free edition" or a scaled down "community edition", but the real deal. You are free to use it in your business and the source code is available online.

On this website you will find resources for the community and by the community around Composite C1 - and we would like to encourage you to get involved and help this project continue to grow.
