What security certifications does Decidim have?
We have independently confirmed GDPR for Decidim. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as Decidim not holding them. Always confirm compliance directly before you rely on it.
Is Decidim open source?
Yes. Decidim is published under the AGPL-3.0 licence, a copyleft licence, so check its terms before embedding it in a closed-source product. Licence terms can change between releases, so verify against the repository for the version you intend to use.

The vioscaleAI score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Decidim, not the verdict.
