What Prism does

  • Your library

    Folders of osu! (.osu), StepMania and Etterna (.sm, .ssc) and Quaver (.qua) maps, browsed by sets. Taps and long notes. Your files stay where they are.

  • Tiered judgement

    Separate early and late windows. osu!mania (OD), Etterna (J1 to J9, Wife3) and Prism are mods, and the presets are customisable.

  • Metron difficulty ratings

    MinaCalc, osu!mania, Quaver, Interlude, Daniel and SunnyXXY, computed in the background; you choose which one is shown.

  • Replays and analysis

    Replays are re-judged by the same engine. The analysis shows every hit, the distribution, the progression and the long notes.

  • Skins, mods and themes

    Folders read from disk next to prism.exe: nothing is hidden inside the executable. A skin editor is built in.

  • Maps from the game

    The game's Download page searches osu!, Quaver and Etterna maps and installs them into your maps folder.

Updates from inside the game

This site is for the first install. After that Prism updates itself from Settings → About: it reads this site's list of releases and sends nothing about you.
