What's your favorite CICD tool?

What's something you've gotten into your CICD pipeline recently that you like?

I recently automated a little bot for our GitHub CICD. It runs a few tests that we care about, but don't want to block deployment, and posts them on the PR. It uses gh pr comment --edit-last so it isn't spammint the channel. It's been pretty helpful in automating some of the more annoying parts of code review.
