I just wanted to test Fritzing today, but it is not so easy to download the program. On the website it is only possible to download it after a PayPal donation. Unfortunately the binaries are not available on github. Please don’t get me wrong, I don’t have anything against donating for free software, but I don’t like to force this on everyone. At the end, I found something after all:
TL;DR: Sign up for an acccount (or use bugmenot.com) and then you can select “I already paid” and download the binary for you platform. If you like Fritzing, please donate.
