I'm looking for a resource that highlights web technologies that are fully supported and can be used right away—no polyfills or extra layers needed. There are many blogs and feeds covering the latest in CSS, JS, HTML, and browser APIs, but I want something specific. For example, there's a new CSS if() function, but I'm only interested when it's widely supported, not just recently introduced. I'd like to receive notifications based on implementation status and market share, rather than just the age of the feature. Does anyone know of such a feed?

You might want to visit caniuse.com for detailed support info, but I get what you're saying—I want to see updates in a feed format too!
Check out the "Baseline" label on MDN. It's specifically designed for features that are widely supported and safe to use right now.
MDN's baseline indicator is great! If you’re looking for a quick rule of thumb, go for the green indicators. Also, new HTML and CSS features usually don’t break anything; they just improve support over time.
