The software lies within Internet & Network Tools, more precisely Network tools. We recommend checking the downloaded files with any free antivirus. This free software for Mac OS X was originally created by The uProxy Authors.
From the developer:
uProxy is an easy-to-use open-source app that allows you to access the web securely and free of restrictions. With uProxy for macOS, you can connect to either a uProxy or Shadowsocks server with just a few taps. uProxy also improves your privacy, since it encrypts all traffic between you and your server.
You may want to check out more Mac applications, such as FoxTrot, IPNetShareX or CVS Set-Up, which might be similar to uProxy.
