Our system is designed to be run around the world in multiple countries in a distributed fashion, which is why we can't provide a standalone implementation and instead only provide GrabzIt's API and Screenshot Tool.
Often the main reason given for wanting to install GrabzIt Capture Software on a customer's own server is due to security concerns. To answer this concern we provide an encrypted capture feature the ability to send captures using HTTPS and as a final safeguard the ability to drastically shorten the time a capture is cached on our servers.
