Native macOS tools you can install
Jan 2026
ThePort and Mermaid Editor ship as .dmg releases — ports, processes, and diagrams without leaving your machine.
Infrastructure visibility should stay local and inspectable. ThePort maps listeners and processes on macOS. Mermaid Editor is a native diagram surface with live preview.
Both ship from GitHub Releases. Download, open, and keep working offline-friendly.
Open tools sit beside commercial products under OVVLO — same bar for craft, different delivery model.
