Key features

  • Clear output: you can tell easily whether anything is good or bad
  • Ease of installation: It works for Linux, Mac OSX, FreeBSD and WSL/MSYS2/Cygwin out of the box: no need to install or configure something, no gems, CPAN, pip or the like.
  • Flexibility: You can test any SSL/TLS enabled and STARTTLS service, not only webservers at port 443
  • Toolbox: Several command line options help you to run YOUR test and configure YOUR output
  • Reliability: features are tested thoroughly
  • Verbosity: If a particular check cannot be performed because of a missing capability on your client side, you'll get a warning
  • Privacy: It's only you who sees the result, not a third party
  • Freedom: It's 100% open source. You can look at the code, see what's going on and you can change it. Heck, even the development is open (github)
  • Documentation: Yes!
