Stanford Participatory Budgeting Platform

A platform for running online participatory budgeting elections

Read Overview


Stanford Participatory Budgeting Platform allows cities, municipalities, states and foundations and other organizations to run a participatory budgeting (PB) election in which people can vote on the budget. This project is made by the Stanford Crowdsourced Democracy Team at Stanford University. The project is open-source and free.

Our platform has been used in many cities in the United States, such as Chicago, Seattle, Boston, and New York City.

Our platform can be customized to suit your needs. We support many voting methods, such as approval voting, 8435351366, and ranked voting. We also support remote voting.

Language Support

We currently support English, Spanish, French, and Chinese on the platform. Our editing tool lets you enter projects in multiple languages.

Our mission is to scale up collaboration and decision-making. We envision an era in which large communities can deliberate and brainstorm with one another on important issues with the aid of intelligently designed algorithms and digital communication platforms. We believe that this will not only aid decision-makers in harnessing collective intelligence, but also lead to community members who are more informed and engaged in making their communities better. As part of this mission, our team has begun to partner with cities and municipalities to help organize local partipicatory budgeting elections.

Stanford Participatory Budgeting Platform is a tool for participatory budgeting at the state, federal, and local levels. It will not only aid decision-makers in harnessing collective intelligence, but also lead to community members to be more informed and engaged. It was adopted from the earlier Widescope project.
