Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

BuiltWith

  • Free tier limited to individual site lookups with no features
  • Basic plan severely limited: 2 technologies, 2 keywords, 2 reports
  • Single login user on Basic and Pro plans
  • Minimum paid plan is $295/month
  • No monthly payment option mentioned; minimum 1-month term annual

FireMonkey

  • Firefox only, and requires a recent one: version 93 on desktop, 113 on Android.
  • Not a drop-in replacement for Greasemonkey, Tampermonkey or Stylus. The project says so itself, so an existing library may need adjusting.
  • A much smaller user base than Tampermonkey or Violentmonkey, which means fewer people have hit the bug you are about to hit.
  • No Chrome, Edge or Safari build, so it cannot be the answer for anyone working across browsers.
  • Combining scripts and styles in one extension also combines the blast radius: one extension with permission to inject both into every page.
