Tendenci is completely free, and you can download and host the platform wherever you like.
Tendenci terms (as written on their website):
You could have a local developer set up a site for you if you wanted. The Tendenci platform can be downloaded at https://github.com/tendenci/tendenci– no gimmicks. You have the voluntary decision to move to your own server in the course of time – even if you decide to host with us – nothing can be taken away from you. Ever. We can even push backups to your own Amazon bucket every night. Again, that is the power of Open Source.
Mr. Free Tools is a free & open project developed to help people reach their full potential and create more equal opportunities by highlighting free solutions. Support the cause and share an amazing resource with your followers!
