In 2007, Josep Sanz Campderrós and Alex Muller founded the company Wide Spectrum Software Solutions (WS3).

SaltOS was created as an internal development to solve its own requirements: the WS3's management

After searching through numerous existing projects, they found that there were several solutions but all had drawbacks:

• Used servers based on Java technologies, which made complex and expensive to find hosting companies that give these services.
• The coding was not layered, with HTML, CSS and PHP mixed in the same piece of code.

All this led to consider the development of a custom application using PHP, XML, XSLT and Javascript technology resulting in SaltOS.

From the beginning, an approach to SaltOS over development framework that does not end application and eventually was given, this application was growing and allowing implementation features that make it an implementation of integrated management of the company.

Josep Sanz believed in the philosophy of Free Software and wanted to contribute their bit for the community by releasing the SaltOS and RhinOS projects such as free software under the GPL-3.0 license.

Currently, the company has ceased operation, and Josep Sanz Campderrós, co-founder of the company, continues its own with the development of these free software projects released under GPL-3.0

Any person or company wishing to use our products, can do so without paying any license, initial or annual. This amount represents a cost saving that can be invested in the customization and adaptation of the product.
