Welcome to difficalcy-performanceplus

This is a difficalcy calculator for the PP+ (PerformancePlus) algorithm.

The core PP+ algorithm was originally developed by Drezi as part of the PP+ project.

Later, with Drezi's permission, I (Syrin) ported the algorithm to lazer to release it open source.

This project can be used to run the PP+ calculator easily within your own projects.

Basic usage

Run the server:

docker run -p 5000:80 ghcr.io/syriiin/difficalcy-performanceplus:latest

Call the API:

curl "localhost:5000/api/calculation?BeatmapId=658127"

Get your lazer powered calculations:
