FTP rush is free software, and it will always be free. We need you to help us improve it together, you can send us bug reports and suggestions. We also need translators to translate FTPRush into different languages. The translation is very simple, just create a new json file in the language directory and translate the entries in the "English.json" file. Your name will be listed as a contributor here and in the about dialog.
