Solid aims to radically change the way Web applications work today, resulting in true data ownership as well as improved privacy.

When using the Web, people should have the freedom to choose where their data resides and who is allowed to access it by decoupling content from the application itself. Because applications are decoupled from the data they produce, users will be able to avoid vendor lock-in by seamlessly switching the apps and personal data storage servers, without losing any data or social connections. Developers will be able to easily innovate by creating new apps or improving current apps, all while reusing existing data that was previously created through other applications.
