Who’s behind the platform?
Metadecidim is the community that collaborates in the design of the platform and the development of the project. Together we design and create new features and report bugs for continuous improvement of the platform.
The Decidim Free Software Association is a democratic association for the governance of the Decidim community.
We suffer under a lack of public space. It's particularly important that we reclaim these public spaces for us. Open platforms such as Decidim do exactly that. Is not only that is open source so other people can fork it, reuse it and build a process. It also has these values that we want to reflect in our society encoded in the way it's designed.

Gracias a Decidim, hemos conseguido en Barcelona coproducir un plan estratégico de ciudad conjuntamente con la ciudadanía. En el 2016 inauguramos el Plan de Acción Municipal en forma de proceso participativo a través de Decidim Barcelona. Actualmente dicho plan recoge casi 7 mil propuestas ciudadanas. Una de las ventajas de utilizar esta plataforma es que puedes seguir en todo momento el estado de implementación de las propuestas aceptadas.

La plataforma digital Decide Mérida fue una oportunidad que abrió como nunca los mecanismos de participación ciudadana para la elaboración del Plan Municipal de Desarrollo de Mérida 2018-2021. Tuvimos más de 3 mil interacciones ciudadanas entre propuestas, comentarios, sugerencias y apoyos que dieron lugar al mayor consenso posible sobre lo que es mejor para nuestra ciudad. Sin duda, la plataforma Decide Mérida seguirá siendo nuestra aliada para hacer de Mèrida una sociedad cada día más participativa.
