Scratchrunner

Scratchrunner runs Scratch 3, 2, and 1 projects really fast by compiling them to JavaScript. Try it out by pasting a project ID or URL into the field below, selecting a project file, dropping a file on the page, or exploring the examples studio.

The future of unshared projects

June 1, 2022 - Unshared projects will no longer be accessible using just their project ID at some point in the future due to upcoming Scratch API changes. This affects Scratchrunner, embeds, and all other third-party sites.
