a11y-probe opens your page in a headless browser, presses Tab until focus is back where it started and prints every stop: what was focused, whether you could see it, and the name a screen reader would announce.

Usage

npx a11y-probe https://your-site.com/checkout --width 390

 1  a      "Skip to content"        ring ok
 2  a      "Northwind home"         ring ok
 3  button ""                       NO NAME
 4  input  "Card number"            ring ok
 5  div    (focus lost)             NOT VISIBLE

What it catches

• Controls with no accessible name
• Focus that lands on something invisible or off screen
• Focus traps, and menus you cannot leave with Escape

It exits with code 1 when anything fails, so it can sit in CI next to your tests.
