I actually recently joined a startup working on this problem!

One of our products is a universal linter, which wraps the standard open-source tools available for different ecosystems, simplifies the setup/installation process for all of them, and a bunch of other usability things (suppressing existing issues so that you can introduce new linters with minimal pain, CI integration, and more): you can read more about it at http://trunk.io/products/check or try out the VSCode extension[0] :)
