About Mindwendel

Mindwendel is a lightweight, self-hosted brainstorming tool designed for teams that want to collect and prioritize ideas quickly. It focuses on simplicity: anyone can post ideas anonymously, vote on them, and see results update in real time. The tool is built with Ruby on Rails and Stimulus, making it easy to deploy on your own infrastructure.

Mindwendel supports categories for organizing brainstorms, real-time synchronization via ActionCable, and a clean interface that works on desktop and mobile. It integrates with nothing out of the box, but its open nature means you can extend it. The project is maintained by b310 digital, a German consultancy, and follows a permissive MIT license.

This tool is ideal for remote teams, retrospectives, or any session where you want honest input without hierarchy. Since it is self-hosted, you have full control over data privacy. The GitHub repository is active, with regular releases and a straightforward setup using Docker or manual install.
