yamu
Yandex Music has no public API and its endpoints refuse cross-origin calls, so nobody could put their playlist on a portfolio the way Spotify users do. yamu collects it in a scheduled GitHub Action inside your own repository and commits static JSON and an SVG card. The whole setup is one playlist link — no login, no token, no hosted service, and nothing of yours stored anywhere but your own repo. The playlist in my lab note about it is the first thing using it.
