Hey, sorry I missed your comment - it can be self hosted. Both the cinch worker and cinch server are self hostable. For my projects I run a cinch worker on my local machine, and the cinch server (which receives webhooks) runs on cinch.sh. But, again, you could self-host the cinch.sh webhook receiver portion.

RE: Makefile. The point is that the runner just runs a command - meaning the CI doesn't have an opinion on what that command should be. All my projects use make - but you could just run `go build` instead! The cinch yaml typically has two keys - the build command and the release command, that's it.
