OpenSlides is a free and open-source web-based presentation and assembly system for managing and projecting agendas, motions, and elections in meetings and committees.

🚀 Overview

OpenSlides is a powerful, modern tool designed to digitize the organization of meetings, committees, and large assemblies. It centralizes agenda management, speaker lists, motions, elections, participant administration, and voting into a single web platform accessible via one URL.

This project solves the challenges of traditional paper-based or fragmented digital meeting management, especially in complex scenarios like political conventions, union congresses, or NGO assemblies. It enables legally compliant secret ballots, weighted voting, and scalable committee structures—from small boards to national events.

Built for democratic organizations worldwide, particularly prevalent in Germany among parties like SPD, FDP, and unions like DGB and ver.di. It was developed to make assembly processes efficient, transparent, and sustainable, evolving from open-source roots to include professional hosting.
