If you find SFTPGo useful please consider supporting this Open Source project.

Maintaing and evolving SFTPGo is a lot of work - easily the equivalent of a full time job - for me.

Maintaining and evolving SFTPGo is a lot of work - easily the equivalent of a full time job - for me.
|
||||
|
||||
I'd like to make SFTPGo into a sustainable long term project and would not like to introduce a dual licensing option and limit some features to the proprietary version only.
|
||||
|
||||
If you use SFTPGo, it is in your best interest to ensure that the project you rely on stays healthy and well maintained.
|
||||
This can only happen with your donations and [sponsorships](https://github.com/sponsors/drakkan) :heart:
