Web based or local: OpenCATS can be installed in a variety of environments. For the solo recruiter/single user, OpenCATS can be installed on your local computer, accessible only by you. OpenCATS can be installed on a local network, accessible by everyone within the office, with no limit on users, yet still protected and removed from the outside internet. OpenCATS can also be installed and accessible via the internet, through a public facing web server, A VPS, a shared-hosting environment, so multiple users from all over the world can access and use OpenCATS together. Keep in mind though, that because OpenCATS is open source software, security is your responsibility. Make sure the appropriate measures are taken for the setup that you choose.
