Decidim

What Decidim does

Decidim is a free/libre, open-source participatory democracy platform operated by the Associació de Software Lliure Decidim, a Spanish nonprofit association headquartered in Barcelona. Founded in 2016 as an initiative of the Ajuntament de Barcelona's Laboratory for Democratic Innovation, the platform enables municipalities, regional and national governments, supranational bodies, NGOs, and cooperatives to deploy digital infrastructure for citizen participation — covering strategic planning, participatory budgeting, public consultations, citizen initiatives, assemblies, and referenda. The platform is distributed at zero licensing cost and is financed through voluntary donations via OpenCollective and membership fees paid by institutional supporters including the Ajuntament de Barcelona, Generalitat de Catalunya, and Localret.

The platform is built on Ruby on Rails as a modular framework of mountable engines and gems, organized around two architectural primitives: "Participatory Spaces" (Processes, Assemblies, Initiatives, Consultations, Conferences) and "Components" (Proposals, Meetings, Budgets, Accountability, Debates, Surveys, Sortitions, Blog, Pages). Notable technical features include multilingual support across at least eleven languages, a GraphQL API with OAuth and token authentication, mapping integrations with Mapbox and OpenStreetMap, ephemeral verification for anonymous voting, and a privacy-with-verification model that preserves participant uniqueness without exposing personal data. The project is released under AGPLv3 with content under CC BY-SA and Open Database License.

Customer adoption is anchored by high-profile public-sector deployments — including the European Commission's Conference on the Future of Europe, the Brazilian Presidency's Brasil Participativo platform, the French Assemblée Nationale petitions platform, the NYC Civic Engagement Commission (formalized via MoU in June 2026), Helsinki City Government's OmaStadi, and the City of Barcelona, where 30 million euros were allocated through participatory budgeting across 2020–2023. The platform is governed by the Metadecidim community, which hosts the project's own roadmap, governance votes, and bug reporting, and has grown to over 39,000 registered participants.

Broad incumbents

• OpenGov: US-based software company providing budgeting, permitting, and civic engagement tools to 2,000+ US state and local governments. A broader government-tech incumbent whose civic engagement suite overlaps Decidim's municipal government use cases but sits inside a much wider ERP-style product portfolio.
• Granicus: Major US government technology vendor covering communications, service delivery, and civic engagement for 5,500+ government agencies. Its govDelivery and engagement modules compete with Decidim in North American municipal procurement, particularly for councils seeking single-vendor procurement relationships.

Direct peers

• Consul: Open-source civic participation platform originally developed by Madrid City Council, Spain. Closely mirrors Decidim's value proposition — free, modular, self-hosted, used by municipalities for participatory budgeting, proposals, and debates. The two are the most comparable open-source civic-tech projects in the European market.
• CitizenLab: Belgium-based SaaS civic engagement platform serving 300+ governments across Europe and North America. Offers the same core use cases (participatory budgeting, ideation, consultations) as Decidim but as a paid managed service, making it the most direct commercial competitor in the same buyer segment.
• LiquidFeedback: Open-source liquid democracy platform developed in Germany, enabling delegated voting and proposal workflows for parties and associations. Comparable technology philosophy (free software, delegation, proposal-based participation) though narrower in scope than Decidim's full participatory stack.
• Bang the Table (EngagementHQ): Australian-headquartered civic engagement SaaS used by 500+ governments globally. EngagementHQ provides surveys, ideation, place-based engagement, and budgeting — directly overlapping Decidim's component set — and represents the established commercial alternative in Anglophone markets.
• Loomio: Open-source cooperative decision-making platform used by organizations, cooperatives, and NGOs for proposals, polls, and threaded deliberation. Targets the same secondary segments as Decidim (associations, cooperatives, civil society) with similar transparency and voting principles.
• Citizen Foundations (Your Priorities): Icelandic open-source civic engagement platform offering crowdsourced legislation, participatory budgeting, and petitions. Targets municipalities and parliaments — directly overlapping Decidim's citizen initiative and petition use cases in the Nordic and European markets.

Emerging players

• Pol.is: Open-source real-time deliberation platform using AI-assisted consensus mapping. Adopted by the Taiwanese government for vTaiwan and used in civic consultation contexts overlapping Decidim's Debates component, though narrower in functional scope.

Others

• Decidim is open source — Discourse: Open-source community discussion platform used by thousands of projects including Metadecidim-adjacent communities. Not a direct civic-participation competitor but a common infrastructure alternative for organizations considering participatory forums, and a community-software adjacency.
