I built an offline, lightweight VS Code extension to preview responsive designs in real device frames
Short summary
ViewPort is a lightweight, offline VS Code extension that previews responsive web designs in real device frames—iPad, Pixel, Desktop—directly in your editor. It eliminates context-switching between editor and browser while maintaining complete privacy with zero telemetry or data tracking. All code processing runs entirely locally without consuming system resources.
