Arythm
Open-source web music player powered by YouTube Music.
Overview
Problem
Most web-based music players are either locked behind subscriptions, bloated with ads, or lack features like synced lyrics. Developers and music lovers need a clean, free alternative that runs entirely in the browser.
Solution
Built an open-source music player that streams from YouTube Music's catalog, displays time-synced lyrics, and provides a polished listening experience — all without requiring user accounts or subscriptions.
