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

Stay

  • Apple only. No Chrome, Firefox or Edge build, so it cannot serve a cross-browser workflow.
  • The free tier is deliberately limited, so the practical product is the paid one.
  • Compatibility with Tampermonkey and Violentmonkey scripts is a translation layer rather than the real thing, and a script relying on an unusual GM function may not behave identically.
  • It bundles bookmark sync, downloads and dark mode alongside the script manager, which is more surface area than some people want from an extension with access to every page.
  • A much smaller project than the established managers, so fewer scripts are tested against it.
