Pick the topic you want, paste this snippet into your page, change the src URL to match the topic. The widget is theme-aware via prefers-color-scheme — it adapts to your visitors’ OS theme automatically.
Notes
Each widget shows the 5 most recently added resources for that topic. The list refreshes every cron build (twice daily, midnight + noon ET). Resource links open in a new tab; the topic title and the “More →” footer break out of the iframe to take readers to the full topic page on appsec.fyi.
No JavaScript, no tracking, no cookies. Width is responsive; pick a height that fits your sidebar (about 320–400px works well for 5 items).
If you embed one of these on your blog, drop me a note — I’d like to know where they end up.
