This website processes gcode files where it will reduce cutting forces by making the feedrate of the gcode dynamic (slower in high force areas)

All computation happens local and inside your browser, no information is uploaded or sent over the internet. For large files this can take 10+ seconds before the results show up.

The tool currently only adjusts feedrates for regular endmills doing 2D operations. 3D/Vbit/ball operations are for a future addition. Also javascript diverges hugely between browsers; the Chrome browser is tested the most. I'll try to make others work on a best effort basis.
