TLDR - A friend showed me a small macOS-only menu bar app that lists local dev ports. I'm one of the dozens of people who uses Linux (Fedora KDE in particular) as my primary operating system. I used OpenCode to fork and create a working KDE Plasma widget called Portmanteau . I keep encountering the same problem: I see a cool, new AI or developer tool that I want to try, except they all seem to be macOS only. A few years ago that usually meant time to move on. Now I tend to think, "I can probably fork that." This time the tool was Port Menu , a simple little macOS menu bar app for seeing local development servers. If you run a bunch of Vite, Rails, Django, Flask, Next.js, or whatever servers during the day, the basic idea is obvious: show me the ports, tell me which project owns them, and let me open or kill them without spelunking through terminal tabs. But again, macOS-only, so I did what any enterprising vibe coder would do.…
