Where each one falls short

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

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.

Raindrop.io

  • No offline access to bookmarks
  • Free plan limited to 100 MB per month file uploads
  • Free plan limited to 3 highlights per bookmark, Pro unlimited
  • Full-text search only available in Pro plan
  • No self-hosted deployment option
  • No enterprise SSO or SAML support
