Hi, I'm the founder of Dagger. I can't speak to the negativity, but if you're looking for a way to make your CI more portable, I recommend joining our Discord and asking our community directly about the pros and cons of using Dagger. Even if you don't end up using it, there are a lot of people there who are passionate about CI and can recommend other alternatives, in a more constructive and pragmatic way than you are getting here.
