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
Userscripts
- Safari cannot let extensions bypass a site's Content Security Policy, so strict sites produce "Refused to execute a script" errors that the @inject-into workaround does not always fix.
- Apple only. There is no Chrome, Firefox or Edge build, so it cannot be a cross-browser answer.
- iCloud sync is documented as having delays, which is awkward when editing the same script on two devices.
- Requires macOS 12 and Safari 14.1, or iOS 15.1, so older Apple hardware is excluded.
- GPL v3 means a commercial licence is required for non-open-source use, which matters if you are embedding rather than just using it.

Yes, free on the App Store and licensed under GPL v3. A commercial licence is required for use in something that is not itself open source.
