There are two ways you can get RosarioSIS. Either you host it yourself, for example on a server or on your computer, or you can use rosariosis.com cloud service. In both cases you keep full data ownership.
Self-hosted RosarioSIS
Run RosarioSIS on your own web hosting, providing PHP and a SQL database. There is no cost for RosarioSIS itself, but you’ll need to update RosarioSIS when new releases are available to keep it secure.
Cloud-hosted RosarioSIS
Forget technical tasks if you decide to go with rosariosis.com. Install, updates, backups are fully managed on a dedicated infrastructure, tailored for RosarioSIS. You will also get dedicated support from the makers of RosarioSIS.
