asim9115/containerix ? reverse-engineered prompt

Build me a self hosted mini PaaS where I can paste a GitHub repo URL and it will automatically clone it, build it into a Docker container, and give me back a live URL and build logs. I want users to be able to sign up, get an API key, and use that key to start deployments through a simple HTTP request. The app should stream progress while the build is happening, then run the container in a locked down sandbox with CPU and memory limits, and keep track of everything in a local database so it still works after a restart. It should support common app types like Node, Python, and Go, or use an existing Dockerfile if the repo has one. Make it feel like a lightweight version of Railway or Render that I can run myself on one server, and include basic health checks, restart recovery, and safe handling so random input can not break the deploy process. If you need to check current docs online, go ahead.
