Does It Fit
Responsive testing on more than 100 real devices
Does It Fit shows a website or a local dev server in the viewports of 123 real devices at once, from an iPhone to a large monitor. Each device gets a sticker saying whether the page fits, is getting tight or overflows, with the measurement in pixels. The tool is free and needs no sign-up, an optional script in the head makes measurements more precise, and AI assistants can be connected.
Why it made the cut- 123 devices with real CSS viewports
- Works with localhost too
- Connects to Claude, ChatGPT or Cursor
