The Sugar Learning Platform is a leading learning platform developed for the One Laptop per Child project and used every day by nearly 3 million children around the world. With Sugarizer, you could discover the Sugar Learning Platform on any device: from the tiny Raspberry PI to the small Android/iOS tablet or the bigger PC/Mac. Enjoy the experience and help us reach every children on every device in every country.
Sugarizer is distributed in the form of 3 components:
- Thin Client: remote access to Sugarizer using a browser,
- Client: Sugarizer running locally,
- Server: place to run remote Sugarizer features.
Thin Client

Sugarizer Thin Client is Sugarizer in a browser. It could work on any device with a recent Chrome/Chromium version, and has also been tested successfully on Firefox, Safari and IE. Sugarizer Thin Client doesn't need any installation on the device but requires a permanent access to a Sugarizer Server.
Features of Sugarizer Thin Client include:
- Sugar Desktop view (Radial, List and Journal),
- Sugar Local data store storage - limited by the browser to 5Mb (see here),
- Running of remote stored Sugar Web Activities,
- Backup or sharing of local storage content to the Server,
- Presence and collaboration
Note: You can run sugarizer from the link above, but the Thin Client access is provided by all the Sugarizer Servers, so you can use others as well.
Client
Sugarizer Client is Sugarizer installed locally on the device so it does not require any access to the Server - it works stand-alone. Server access could be required only when it needs network features. Sugarizer could work on any device with a recent Chrome/Chromium version and has also been tested successfully on Firefox, Safari and IE. Sugarizer Client is available for PC, for Android, iOS, Chrome Web App and for Firefox OS devices.
To install Sugarizer on a PC (GNU Linux/Mac OS/Windows), download the file org.olpc-france.sugarizer.zip, unzip its content, then launch Chrome using the command line:
chrome --allow-file-access-from-files
Then open the "index.html" file in the browser. Note that the option "--allow-file-access-from-files" is needed to authorize access to local file. Don't forget to close all other instances of Chrome before using this option. For other browser equivalent options see here. Do not hesitate to write a shortcut on this command for future use.
Note that if your browser is Chrome you could install Sugarizer as a Chrome Web App, just go to the Chrome Web Store (see here) and click on it. It will avoid you any installation.
Also, in case you are not able to make sugarizer work on Chromium on Ubuntu, you might want to consider trying to run it on Firefox.
Features of Sugarizer Client include:
- Sugar Desktop view (Radial, List and Journal),
- Sugar Local data store storage - limited by the browser to 5Mb (see here),
- Running of locally stored Sugar Web Activities,
- Capability to connect to a server to backup or sharing local storage to the Server,
- Presence and collaboration
Server
Sugarizer Server is the back-end for network features of Sugarizer. It means: allow deployment of Sugarizer on a local server, for example on a school server, so expose locally Thin Client (without Internet access). Sugarizer Server can also be used to provide collaboration features for Client and Thin Client on the network. Sugarizer Server could be deployed on any computer with Apache2, Node.js and MongoDB.
Sugarizer Server features include:
- Sugarizer Thin Client access,
- Backup and shared storage for Client and Thin Client,
- Presence and collaboration handling between Client/Thin Client on the same network
A Sugarizer server instance is accessible here.
