- Towards data freedom
Technical Specs - Introduction

freezr is an open source personal server, built on node.js.

It acts as a thin layer providing identity and permissions management, to connect apps to the data owner's files and data.

Apps define their parameters and permissions via an App Manifest

Apps communicate with the server via a Core API which is CEPS-compatible.

Apps can be independent third party apps outside of the freezr server (eg a smart phone app that communicates with your freezr, or even a third party server that stores your data on your freezr.) But freezr also allows html apps to be served from your freezr server. Such a "freezr app" is just a collection of html, css and js files which you can "install" on your server. ie you just download the html/css/js files on your freezr, define how a page should be served in the manifest and then

Within freezr, all data is stored within a user's preferred storage medium - their personal data store, which can be on Google, or AWS or Dropbox, or any other storage medium that is connected to freezr via its Storage API. Here, data refers to actual data sitting in the freezr database, any files which you store there (eg pictures), as well as the freezr-app's actual program files (ie html/css/js files served.)
