RedPP ავტორი Red

RedPP is a click-the-toolbar pp calculator for osu! beatmaps.

Open any beatmap page on osu.ppy.sh, click the RedPP icon, and you'll see a clean popup with:

• Star rating + AR / OD / CS / HP / BPM (mod-adjusted live)
• 8 mod chips (HD, HR, DT, FL, EZ, HT, NC, BL) — toggle any combination to see what-if pp
• Accuracy slider from 0% to 100%, full granularity
• Rank-by-accuracy badge (D / C / B / A / S / SS) updates as you drag, matching osu!lazer's grading


thresholds

algorithm osu!lazer itself uses for performance points. No backend, no API key, no login required.

How it works:
1. Open any beatmap page (osu.ppy.sh/b/123, /beatmaps/123, or a beatmapset page with a difficulty
selected).
2. Click the RedPP toolbar icon.
3. Drag the accuracy slider, click mods, see pp update in real time.

Permissions explained:
• activeTab — to read the URL of the active tab so we can detect the beatmap ID.
• storage — to cache fetched .osu files in your session (cleared on browser close).
• osu.ppy.sh / assets.ppy.sh — to download the beatmap and its cover image.
