contribution-checker
Gates pull requests behind a contributor application, as a GitHub App or from inside GitHub Actions.
Self-hosted app that gates pull requests behind a contributor application form. A GitHub App, or a pair of Actions workflows where an App cannot be installed, closes pull requests from contributors who have not been approved, then reopens them once a maintainer approves. Built for Postiz work and open sourced under AGPL. It may move into GHub later, but it sits with the Postiz work for now.
contribution-checker is built and maintained by Gelhaus Solutions. The detail, what it does, how it is built and where it stands, is on their site.
