Disroot aims to change the way people are used to interact on the web. We want to encourage and show them not only that there are open and ethical alternatives but also that it is the only possible way to break free from the walled gardens proposed and promoted by proprietary software and corporations, either through our platform, others that have similar values and goals or even their own projects.
