I asked Claude and Gemini to build a Docker app—one was smoother, the other smarter

I’ve been vibe-coding small apps for a while now, and the biggest problem with them is that they live and die on the machine they were built on. Ideally, you’d want to self-host these apps so they’re accessible across all your devices. So, this time, I’m testing Claude vs. Gemini to see which model does a better job of building a Dockerized app and making the self-hosting process as simple as possible.
