The goal of this web optimized port is to make FNF and this mod more accessible to players that can’t otherwise play it on their potato PC, on a Chromebook,  on their Mac, on their Linux, or simply can’t run the EXE files on their computer. Also help save hard drive space. Please keep in mind that this online web port might be slightly different and/or have missing mechanics than the PC version. So make sure to also get the PC version if you have a PC.

If you want a challenge, turn off Ghost Tapping in the settings.

Recommend using Google Chrome to play FNF Mod for the best performance.

Jam to the beats and just have fun!
