Heroku lets app developers spend their time on their application code, not managing servers, deployment, ongoing operations, or scaling. We are strong believers in free and open source software, and much of our code is available on our GitHub page. We are offering cash rewards on an ongoing basis for valid vulnerabilities, subject to the rules and terms of participation. The goal of this bounty is to find vulnerabilities which affect the confidentiality, integrity, or availability of our services and code.
