It claims to be open source but it seems to be only in name. The web site says you can use it for free for personal use, but such a claim makes it NOT open source by definition. (Source-available at best.)
I had to dig really hard to find a link to github (https://github.com/ispysoftware/iSpy) but I get the impression from the README and lack of activity that this repo was superceded by another product from the same company, and that appears to be what the main website is marketing for download/payment. And according to the license file, some rather important bits of it are not open source at all.
