TurboWarp is a Windows tool that helps users efficiently execute the Scratch code with a more optimized and mature JavaScript runtime. Moreover, it is possible to eliminate unnecessary processing such as sprite updates and sound playback from the project.

Optimization

You can paste code snippets or import compatible files to begin improving a custom program. Like in dotTrace, there are instruments for automatically identifying common optimization opportunities like removing redundant operations and simplifying complex expressions.

As a result of these improvements, the performance of Scratch projects can be increased significantly. Complex applications with multiple sprites, sounds and animations may benefit from the optimization the most.

Settings

The Preferences menu offers users a checkbox for enabling interpolation to smooth sprite motion. Moreover, options to remove various artificial limitations such as fencing are provided. There are tools for specifying a custom stage zone as well. It is possible to store custom parameters inside a project or save multiple separate profiles and switch between them as needed.
