Since the first commit on August 22, 2016 Judge0 API was and will remain open-source project with free to use public instance located on

Since then Judge0 grew more than I expected. More than 2.7M submission where made, Judge0 IDE was created, more than 300 commits were pushed across all Judge0 repositories and more 400 hours of my time was invested into it.

Alongside my PayPal account, I have opened up a Patreon page where you can support my work and Judge0 project.

Your support will help me spend more time on developing Judge0, scale the public instance of Judge0 API and much more!
