I find it makes my life easier, personally, because I can set up and tear down environments I’m playing with easily.

Same here. I self-host a bunch of dev tools for my personal toy projects, and I decided to migrate from Drone CI to Woodpecker CI this week. Didn’t have to worry about uninstalling anything, learning what commands I need to start/stop/restart Woodpecker properly, etc. I just commented-out my Drone CI/Runner services from my docker-compose file, added the Woodpecker stuff, pointed it to my Gitea variables and it ran docker compose up -d.

If my server ever crashes, I can just copy it over and start from scratch.
