Tools and Projects for OSC Development and Use


It is INHERENTLY DANGEROUS to run code that someone else has written. Most of the projects below are open-source so you can verify that they are safe to use. If possible, read through the code and compile it yourself instead of using compiled binaries (exe files, etc).


If you would like submit your own project for consideration, please post it to Show and Tell. To be considered, your project should be documented, open-source, include a license, and the project page must not violate or suggest violations of VRChat's TOS, or link to any pages that do. We will update this list weekly, adding and removing projects.

The List
