How Solid works

Personal data pods

Full control of where your pod is stored and who can access it

Solid Pods

Pods can store any kind of data

Personal data, photo's, friends, ...

Solid Pods Storage

Data become decoupled from apps

Centralized App      Solid App

A paradigm shift in app design

Users gain freedom to choose apps

A collection on open standards

Why Solid uses open standards

Solid is an ecosystem

Next steps for Solid

Existing and new standards

Standards are created collaboratively


Choose your Solid pod implementation

Actively being developed by different parties

Choose your Solid pod location

How to build apps on top of Solid?

Apps need to be able to access multiple pods

A centralised social network app

Data is obtained from a single location

Social App

A decentralised social network app

Data is obtained from multiple locations

Each data element can be stored in a different place (posts, comments, likes, ...)
