knobs

Most bugs we ship come from settings we never try: a user in Tokyo, a phone in dark mode, a reader with large text. knobs puts all of those settings in one panel on the page, so we check them in seconds before we ship.

Switch the color scheme, contrast, text size, locale and right-to-left text, time zone, clock, geolocation and device frame. The Chrome extension works on any site; the npm package @vinena/knobs goes inside your own app, in development only.
