Looks like it has more "self service" capabilities. But not sure.
But i think most of the problems are better solved by running an IaC tool like terraform in CI with a pull-request workflow.
neither of them solve for CI or pull request workflows themselves, so people try to bridge the gap with Jenkins and now the frankenstein monster comes to life -- now you've got golang, groovy, yaml, none of which your product devs generally have any familiarity with, let alone the idiosyncrasies of terraform state management, cloudformation stacks stuck in ROLLBACK_COMPLETE, yaml whitespace sensitivity, Jenkins scripting sandbox woes, troubleshooting from logs without being able to step through a debugger in an IDE, errors that only happen in eu-west-3, etc, etc...
Clutch looks great!
