Emulate real devices by using their screen sizes, or use responsive CSS breakpoints.
Reorder, clone, delete, hide, and create devices with custom dimensions, user agent, etc.
When interacting with one viewport, slashB will mirror all your actions (click, focus, scroll, forms input) on the others.
If your local setup supports Hot Reloading, you can instantly see all the changes you make across all the devices.
slashB includes Chrome/Chromium's devtools, with support for devtools extensions like React, Vue, Angular, Svelte and more.
