The Comet gap
What Comet users are looking for
Security and control concerns
Security researchers note that Comet can act with logged-in privileges, persistent cross-session memory, and traffic that appears human — raising accountability questions.
Windows support is newer and less mature
While Comet has expanded to Windows, Tabbit has supported both macOS and Windows from the start with a unified Agent experience.
