pgModeler is an open source software and you can get its source code anytime if you want to compile it for yourself. As a facility, we provide compiled binary packages at a really small price. Also, if you're interested in evaluate a binary package, you can get a demo copy before proceed with the purchase. Since this is an independent project by purchasing any binary package you'll help to keep its development alive and at full speed!
Purchase a binary package and support this project. Pick your platform, choose an expiration period, pay using PayPal™ and enjoy ready-to-use packages.
Get previously purchased binary packages by using an access key. If you bought packages prior to January 2017 you'll need to use the payment conversion tool first.
If you are a package maintainer or just want to compile pgModeler for yourself you can freely get the source code from official repository.
