Docker

The app talks to Apple's container daemon directly over XPC, the same path the CLI uses, and handles images, logs, live stats and in-container file browsing from one window.

The thread's flip wasn't about the tool. One tester wrote that seeing Claude in a project's GitHub contributors is now a signal the app will be good: native-feeling, tiny, no Electron.

The pro-Podman case in the thread was security and ergonomics: no 'container root equals host root' games, no daemon, no holes punched in your firewall. One CTO switched after Docker Desktop ballooned in memory — 'literally as easy as installing it and pointing it at our docker-compose.yml.'

The honest counterweight was portability. Podman's file-per-unit Quadlet model can't match Compose's single, readable, shareable file for team development — and getting current versions on Ubuntu without stale distro repos still, one reader argued, keeps losing Podman to Docker.

The trick is three lines: open file descriptor 3 on /dev/tcp, printf a raw GET with CRLF headers, then cat the descriptor back. The Connection: close header is load-bearing — drop it and cat waits forever.

But the loudest reply in the thread was a correction: Bash does not speak HTTP. It opens a socket and you speak HTTP, badly. The toy client doesn't parse responses and breaks on redirects, chunking, or TLS.
