Common reasons people leave Nikto: command line only, with no graphical interface, and very noisy, so it's easily spotted by intrusion detection. We ranked 5 alternatives by how directly each one replaces Nikto, then by reviews, real visits and how recently each app's facts were checked against its own website. ZAP currently ranks first.
