You wrote that Armory is free for working on Open Source project. But how to get this free license? The only way I see on your site is "Trial License". There is no information about free licenses
Thank you for your question!
Yes, you can get license key for free for your open sourced project. Just send information about the project you working for to this email: email@example.com.
And please don't forget to specify the version of your IDE (PySharm, PhpStorm, etc) in the letter.
