LiquidFeedback is free and open-source software for initiative-based, delegated decision-making. It was developed by the Public Software Group (formerly BCCM GmbH) in Berlin and released in 2009. The software implements a form of liquid democracy: participants can vote directly on initiatives or delegate their vote to a trusted representative, with delegation transitive and revocable at any time.

The platform gained international attention when the German Pirate Party adopted it as their core internal governance tool from around 2010. At its peak, the Pirate Party's LiquidFeedback installation had tens of thousands of active participants proposing and voting on policy positions — an unprecedented scale for liquid democracy in practice.

The initiative process follows a structured lifecycle: initiative → discussion → frozen (final editing) → voting. This prevents premature closure while maintaining a defined path to decision. The software is designed for organisations rather than individual citizens, and has been used by political parties, trade unions, and NGOs across Europe.

The source code is available under a permissive licence. Liquid Democracy e.V. (a Berlin nonprofit) also builds on LiquidFeedback for municipal participation projects.

**Current status unclear.** As of mid-2026, the site operates under FlexiGuided GmbH (the domain redirects from liquidfeedback.org to liquidfeedback.com) and no public development news has been found since 2012. The software may be in stable maintenance rather than active development. If you can confirm current deployments or recent commits, please update this page.
