Breakpoint Tester


Breakpoint Tester is used to quickly and easily test the responsiveness of a website at various breakpoints. Breakpoint Tester ships with some sensible defaults to get you started off right but you’re more than welcome to use your own custom breakpoints.

Breakpoint Tester uses the default media queries that ship with Bootstrap 3 as a baseline for it’s breakpoint presets which are:

480px (Mobile)
768px (Tablet)
992px (Laptop)
1200px (Desktop)

Breakpoint Tester is open source and licensed under the MIT license. You are more than welcome to contribute to development, the project can be found on GitHub:
