osu! Beatmap Preview per dotremilie

osu! Beatmap Preview lets you preview osu!standard beatmaps directly from your browser.
Open an osu! beatmap page, click the extension icon, and view an interactive canvas preview of the map without leaving the page. The popup reads the current osu! beatmap URL, loads the beatmap file from osu.ppy.sh, and renders the hit objects with playback controls, difficulty details, and mod selection.
Features:
- Preview osu!standard beatmaps from osu.ppy.sh pages
- Canvas-based hit object rendering
- Playback controls for scrubbing through the map
- Difficulty metadata display
- Support for common gameplay mods
- Lightweight popup interface
The extension only works on supported osu! beatmap URLs and does not use analytics or a developer-owned server.
