A simple but complete SaaS app that uses an open source library called PHP CodeSniffer under the hood. PHP CodeSniffer can be used to report on style violations in your code but can also be used to apply fixes automatically. The app submits Pull Requests to your chosen GitHub repositories whenever you push code and there is a code style violation.
This app was a side project that I launched but didn't market. There are currently 30 users signed up but none have converted to paying customers. The only overheads are server hosting ($10/month DigitalOcean droplet) and the domain name ($13/year).
