I was tired of starting a project with one linter and formatter, only to realize halfway through that the tech stack I chose wasn't fully supported. Then came the migration: uninstall, reinstall, reconfigure, debug the new config, repeat.
Even when you stick with one tool, the setup is painful. You have to search for the right ESLint plugins, figure out which parser you need, install everything, write the config file, then do it all over again for your formatter. Every. Single. Project.
Sure, you could ask an AI to generate the config for you. But that burns tokens, and you still need to verify it's correct, install the dependencies, and tweak it to your liking. It's not a real solution, it's just shifting the problem.
Config solves this by analyzing your tech stack upfront and generating a complete, compatible configuration in one command. No migrations, no plugin hunting, no wasted tokens.
