Where each one falls short

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

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.

Wappalyzer

  • Cannot detect server-side or hidden technologies without client-side footprints
  • Went closed-source in 2023; self-hosting now difficult without maintaining community forks
  • Data export features locked to Business plan ($450/month) minimum

Answered from the vendors’ own pages

Userscripts: Is Userscripts for Safari free?

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.

Source
Wappalyzer: Does Wappalyzer have a free version?

Yes. Wappalyzer's browser extension is completely free and provides unlimited technology lookups with no account required. The free tier includes basic website technology detection across all categories.

Source
Userscripts: Does it work on iPhone?

Yes, on iOS and iPadOS 15.1 or later, which makes it one of the few ways to run userscripts on an iPhone.

Source
Wappalyzer: What are the paid pricing tiers for Wappalyzer?

Wappalyzer's paid plans start at $250/month for Pro (5,000 lookups, 1 user), $450/month for Business (20,000 lookups, 5 users, API access), and $850+/month for Enterprise (200,000+ lookups, 25+ users). Annual billing offers 17% discount.

Source
Userscripts: Why do I get "Refused to execute a script" errors?

Safari does not let extensions bypass a site's Content Security Policy the way other browsers do. The documented workaround is changing the script's @inject-into setting, though it does not resolve every case.

Source
Wappalyzer: Can Wappalyzer detect all website technologies?

Wappalyzer detects over 1,000 technologies but cannot detect server-side or hidden technologies, backend infrastructure, internal databases, or ERP systems with no client-side footprint.

Source
Userscripts: Do my scripts sync between Mac and iPhone?

Yes, over iCloud, though the project notes the sync can be delayed rather than immediate.

Source
Wappalyzer: Can Wappalyzer be self-hosted?

Wappalyzer went closed-source in 2023 when the GitHub repository was taken down. It can be deployed via Docker or npm, but the community-contributed fingerprint database is now part of the commercial product. Open-source forks are available but not officially maintained.

Source
Userscripts: What are the system requirements?

macOS 12 or later with Safari 14.1 or later, or iOS and iPadOS 15.1 or later.

Source
Wappalyzer: What integrations does Wappalyzer offer?

Wappalyzer integrates with CRM systems like Salesforce and HubSpot, and supports lead list exports and API access for business users on paid plans.

Source
Wappalyzer: When does Wappalyzer data export become available?

Data export and lead list generation features are only available on the Business plan ($450/month) and above, not on the Pro tier.
