Why not use the built-in mobile preview tool that allows you to set custom dimensions?

  I also use that, but I find it faster and more straightforward to just drag the window edge, especially when devtools are not opened. One example is using browser and editor side-by-side on a single macOS split-full-screen.

    You can open responsive mode via a keyboard shortcut without needing the dev tools open; on Windows it’s Ctrl+Shift+M, no idea about macOS but it’s doubtless easy to look up.

      It's the same shortcut on Linux and *BSD and probably everywhere.

    I know you're not asking for advice, but in this case I would use LiveReload against multiple windows covering the breakpoints. Then you'll only need to wiggle edges to check breakpoint transitions.
