Citizen participation platform

Hub for running participatory budgeting, consultations, petitions and assemblies on a self-hosted Decidim platform, and how the organization and its legal duties change the build.

Open source participatory budgeting software

For cities and regions letting residents propose and vote on spending: phases from proposals to voting and project tracking, vote rules and budgets per district, verifying eligible voters, and publishing results with Decidim's budgets and accountability components.

Open source platform for public consultations

For governments consulting on plans, laws and policies: structured processes with phases, comments and proposals, surveys and in-person meetings recorded online, moderation, and publishing how input changed the outcome.

Open source platform for petitions and citizen initiatives

For bodies that accept petitions or citizen initiatives with signature thresholds: initiative types, signature collection with verified identities, deadlines and committee review, and how Decidim's initiatives space models each step.

Citizen participation platform for municipalities

For city councils and municipalities: hosting Decidim within municipal or national infrastructure, integration with the city's identity and census systems for verification, accessibility duties, staff roles and support after launch.

Citizen participation platform for EU data sovereignty

For EU public bodies keeping participant identities and votes under EU jurisdiction: self-hosting Decidim with EU providers, maps, geocoding and social login services that send data abroad, and transfer documentation.

GDPR for citizen participation platforms

Running participation under the GDPR: lawful basis for public tasks, political opinions as special category data, pseudonymous participation, retention of proposals and votes, participant rights and data processing agreements with the host.

Citizen participation platform requirements checklist

A requirements checklist for a self-hosted citizen participation platform: functional must-haves, hosting and data residency, identity and access, privacy and retention, integrations, operations and support, so a team can compare self-hosted options before choosing a platform.

Citizen participation platform RFP questions

Questions to put in an RFP or vendor brief for a self-hosted citizen participation platform: platform and edition fit, licence obligations, migration of existing data, hosting model, security evidence, support terms after go-live and how the fixed scope is defined.

Citizen participation platform cost: build, partner or SaaS

Cost structure for a self-hosted citizen participation platform: subscription pricing published by SaaS vendors against self-hosted infrastructure, implementation, support and internal staff time, which drivers move each line, and when bringing in an implementation partner costs less than building alone.
