I built Contrib.FYI as a simple web app to reduce that decision cost.
Instead of relying on static, curated lists, it uses live GitHub API data and shows issues in chronological order, so discovery stays fresh.
On top of that, it surfaces a few early signals (language, stars, no comments, no linked PRs) to help you avoid opening issues that are already being worked on.
The goal is not to find more issues, but to find better candidates to spend your time on.
