Buy us a coffee
MOBZystems - Home of Tools has been publishing developer tools since 2008 - in other words: for more than 15 years. Originally, we had a paid product called QuickCode, but since that was discontinued long ago all content on the site has been - and will be - free.
These days, See through Windows is our most downloaded tool. We don't keep track of the number of downloads, but there have been tens of thousands since 2011 (!). We have no idea who uses it and what for, but that's OK - it was always just a fun project and not a source of income.
A few years ago, "buying the developer a cup of coffee" was suddenly a thing. A small, one-time donation to show your appreciation, more than anything really. So, a bit late to the party, you can finally buy us a cup of coffee, too, and donate to support more development. (Because more coffee == more productivity, obviously)
