every-app/open-seo ? reverse-engineered prompt

I want to build a self-hosted SEO tool, something like a simple, open-source version of Ahrefs or Semrush. I'm trying to get away from expensive monthly subscriptions and have more control.

It should be a web app that I can run myself. The main features I'm looking for are keyword research to help me find topics, a way to see my domain's search visibility and performance, a tool to check my website's backlinks, and a basic site audit feature to catch technical problems.

I understand this will need to pull data from an external service. Please build it to use the DataForSEO API, since it has a pay-as-you-go model. I'll provide the API key in an environment file. It should be easy to run locally, so please set it up using Docker so I can get it running with a simple command.
