There are two types of packages available
Linnworks Anywhere is a cloud based solution. You still have to install a thin client on your PC in order to utilize the full potential of the rich application interface, but the majority of the work is done by our servers (we call them cloud instances). So basically all the user interface bits are a desktop application which is designed to run under Windows operating system, but will quite happily run under Mac in Parallel mode as well, although we don't officially support Mac. And all the database stuff, crunching and so on is done on our server.
See Linnworks Anywhere Installation Guide
Linnworks can no longer be installed by new customers, if you already have Linnworks Local installed please refer to the following documentation on migrating your database to our anywhere package
See Migrating from Linnworks Local to Anywhere
