How to use the Screen Resolution Tester

Instead of opening a code editor or installing a CLI tool, use Screen Resolution Tester right in your browser. It handles the task locally, giving you fast, private results without context switching.

When to use Screen Resolution Tester

Reach for Screen Resolution Tester during code review when you want to verify that a snippet is well-formed, or when you are working on a remote machine and do not have your usual dev environment set up.

Common use cases for Screen Resolution Tester
