The short version

  • Only Userscripts has a free tier, so it costs nothing to try first.
  • Each has a real cost: Canvas basic analytics lack predictive intelligence or advanced student success insights; 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.
  • They diverge on capability: Canvas covers Course management, Userscripts covers Built-in script editor.

Where each one falls short

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

Canvas

  • Basic analytics lack predictive intelligence or advanced student success insights
  • Course structure is traditional and may not support competency-based or adaptive learning paths without supplementary tools

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.

Answered from the vendors’ own pages

Canvas: Does Canvas work offline?

Canvas has launched offline access for its student mobile app, allowing students to view pre-selected course content without internet. However, offline access is view-only and submissions require reconnecting to the internet.

Source
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
Canvas: What integrations does Canvas support?

Canvas supports hundreds of external applications through its App Center using LTI standards, including video platforms, plagiarism detection tools, and digital textbooks through a standardized integration framework.

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
Canvas: How does Canvas handle course analytics?

Canvas provides built-in reporting that covers grades and student engagement, but lacks predictive analytics or advanced student success insights that some institutions require.

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
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
Userscripts: What are the system requirements?

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