About FlagHero

Save, organise, and apply URL query parameters for product development work. FlagHero lets PMs, CS, ops, and sales teams manage feature flags and URL params with one click. Save flags with notes and tags, apply them to any page instantly, and diagnose flags you can't get working with the built-in Flag Doctor. Includes Reg and Eng modes so it doesn't call query parameters for flags to sore engineering eyes, and literally calls anything else a flag for everyone else.
