Foire aux questions
What does it mean that Decidim is for free, "libre" and open source?

Decidim is a platform for citizen participation made by the people and for people. Its source code is open and can be inspected, modified, and enhanced by anyone. The Decidim software is covered by the AGPL license. That means that you can use it, modify it and redistribute derived versions of it as long as you respect the AGPL license.

Do you have a Demo? I want to use Decidim now, without installing it, to see how it works.

Yes, we have an online demo.

Can I join the Metadecidim community even if I don't live in Barcelona?

Of course you can. People do so through participatory processes, debates, translations, etc. that you might find in Metadecidim. Decidim was born in Barcelona and that is why there is a strong territorial bond with this city, but above all, it's a project for the commons.

What is Decidim?

Decidim is a Free Open-Source participatory democracy platform for cities and organizations. But Decidim is more than a digital platform: it’s a common's free and open project and infrastructure involving code, documentation, design, training courses, a legal framework, collaborative interfaces, user and facilitation communities, and a common vision.
