devknobs
A dev panel that shows your page on any phone, at any time, in any language or theme
Why it made the rally
Add the devknobs npm package in development and your page reloads in a frame sized to an iPhone 18 Pro, a Pixel 10 or the folding iPhone Duo, while the knobs change Date, Intl, navigator.language, geolocation and the user agent. Shift G grabs any element with its React component, file and line for a coding agent, and the whole tool is MIT licensed by mertbuilds.
