Stop Making TUIs. Thomas Ptacek advocates for building real native user interfaces for even the smallest of personal tools, because coding agents have reduced the cost of getting a usable-enough GUI up and running to almost nothing.

I wrote about my vibe-coded bandwidth and GPU monitoring macOS task bar apps back in March, and I'm still using both of those on a daily basis.

I'm not habitually knocking out real UIs for my other projects yet, but I'm running out of excuses!

Thomas:

If you haven’t tried your hand at turning one of your 500 throwaway CLIs into a native app, you’re doing yourself a disservice. Go build a native UI. It’ll probably change the way you think.
