I wonder if anyone is aware of any replacement for Stylish. Stylish is not on the Safari Extension Gallery since they were stealing browsing information.


There is a paid ($3 in US) application Cascadea. I’m happy with it, because it is Safari App Extension instead of the Legacy Safari Extensions (.safariextz files). It seems to only work with User CSS (*.user.css) though, so you may want to write to support team (support@cascadea.app) to confirm before you pay.


I previously used dotjs and dotcss for Safari. As I relied on these a lot, I've written an extension for Safari 12 that provides the same functionality in one extension with a simpler setup.

Not sure if this is enough for your needs as it only offers injection of CSS and JS files based on the page's domain name.

In case you want to find out more, I've written an introductory blog post. The extension is available on the App Store ($5). It's open source, so you're also welcome to compile it yourself for free.


I've actually found Tampermonkey. It's not totally Stylish but it can do the same.

I replaced Stylish with FreeStyler which provides the same functionality just with a slightly worse UI. There’s no automatic import path from files or another extension, so moving styles were a case of manual copy-paste and configuring the applicable hosts/URL prefixes.

  • As the original Stylish (including the Safari version?) had massive security implications and apparently turned really rogue: did you control for that in FreeStyler? – LаngLаngС Oct 3 '18 at 16:00

    FreeStyler has been removed in Safari version 12 and later – Mitoxys Aug 31 '19 at 12:57
