So the only difference with https://www.npmjs.com/package/npm-check-updates is that you run tests after each update? (and that you've a fancy logo ofc)
Are you handling semver like they do? I see no informations about it in the README.
That's is the main feature - running unit tests against a dependency. Because unless you follow semver religiously and use semantic-release and dont-break - your version is human assigned. Thus a patch upgrade can easily break your stuff.
Well i don't know "npm-check-updates" in detail, but this is one difference, yes. For us it is very important to know if and which module brakes the tests. In my opinion it doesn't it is no option just to update all dependencies without running the tests.
