Loomio

Loomio is an open-source platform designed for groups that need to make decisions together. It replaces the chaos of long email chains and noisy chat channels with structured discussions and clear voting. You can propose options, gather feedback, and see exactly where everyone stands before settling on a final choice. The tool works especially well for distributed teams, cooperatives, community organizations, and any group that values inclusive, transparent governance.

Loomio supports multiple voting methods including simple yes/no/abstain, ranked choice, score polls, and consensus checks. Discussions can be kept private or made public. Integrations are available with Slack, email, and a REST API. It runs as a web application on your own server or as a hosted service. The codebase is written in Ruby on Rails and PostgreSQL, and the project has been actively developed since 2012 by the worker-owned cooperative Loomio Cooperative Limited.

Single sign-on via Google, Microsoft, or SAML is supported for larger organizations. The platform itself is free to self-host under the AGPL license. For those who want a hosted instance, Loomio offers a paid SaaS tier with optional support contracts and priority features. Notable users include the New Zealand Green Party, Oxfam, and the Mozilla Foundation.
