OP/author here! Apologies about the malware and captcha. It looks like my site was exploited by CVE-2026-26980 affecting all Ghost sites pre v6.19 [1][2] An API key was hijacked to inject malicious JS into every page that looks like a cloudflare captcha; it seems that the JS only targeted windows users, so I didn't catch it before I shared the post widely.
The site has been upgraded to 6.44 to close the vulnerability, I rotated every API key and account credential, and both manually and programmatically scrubbed every instance I could find of the code injection across the database. I think we're clear now!
Sorry to anyone caught by this and thank you to folks for flagging it (and thanks to the HN team for letting me follow up on this after comments were closed). I'm seriously mortified. X_X

filament
A powerful open-source UI framework for Laravel • Build and ship apps & admin panels fast with Livewire
In a life of everybody should be the moment, the time to separate from the parents. Laravel's Shroomok reached that stage in 12 months or so. Bottle-neck was the absence of nice admin dashboard focused on text-content edits. I mean, of course, there were solutions, but I didn't feel right about them until the King was found -- Filament!

Grav
Modern, Crazy Fast, Ridiculously Easy and Amazingly Powerful Flat-File CMS powered by PHP, Markdown, Twig, and Symfony
I don't even track the clicks, at this point the shortener is just an Apache2 container with a long config file and some shell scripts for me adding new links: https://blog.kronis.dev/blog/sometimes-dropbox-is-just-ftp-b...
Previously it was YOURLS but now it's the simpler setup, the whole reason for me adding it was that Grav (which is otherwise a lovely flat-file CMS) was really bad at handling query strings in Markdown: https://getgrav.org/
Not sure if it's been patched since, will probably look into it at some point. Might either migrate from the shortener to direct links at some point, or add an intermediate page: "You are about to go to: " with some buttons.

Not easily without additional tooling. Hugo has no admin panel — content is Markdown files in a Git repository. You can add a headless CMS like Decap CMS, Tina, or Forestry to provide a web-based editor backed by Git. This adds complexity but makes Hugo accessible to non-developers.
