OpenSSF Best Practices Badge Program
↗ https://www.bestpractices.dev/
A checklist and a badge for best practices in open source repos.
It's a lot like what I was trying to do with https://github.com/sm-th/show-your-work, but mine ended up being more about form and this one is about substance.
You don't have to actually get the badge. You can just use it as a checklist to gauge the quality of your own repos.
