Organisation and project overview

A free platform from a non-profit association



You can use OPIN to start digital participation projects directly, without needing installation or prior technical knowledge.


Non-profit & Open Source

The platform is developed and operated by Liquid Democracy, a non-profit association from Berlin. The code is in the public domain.


Free of charge

OPIN can be used free of charge. We only offer additional services such as trainings for a fee.


The OPIN Community

We want to establish an active and vivid community of project initiators and other interested institutions to enable a peer-to-peer exchange. Accomplished practitioners have valuable knowledge that other, less experienced practitioners can benefit from.  Collaboration and the sharing of advice in a community of like-minded activists can strengthen eParticipation skills across Europe.

We warmly invite you to become an active member of our community.
