Pick an element and get a stable CSS selector

Stable selectors

Built on a proven selector engine, with filters that skip auto-generated ids and hashed CSS-in-JS / CSS-module class names.

Tunable per site

Choose whether selectors use id / class / attributes, set ignore patterns and an attribute allow-list — remembered per website.

Inspector built in

An editable selector with a live match count, a DOM-tree navigator, and the element's attributes — in an overlay that never clashes with the page.

Cross-tab picking

An app can open a URL, let the user pick there, and get the selector routed back — the one thing a page can't do for itself.

Private by design

No servers, no tracking, no data leaves your browser. You choose which sites may use the picker.

Light / Dark / System

The picker, popup, and options follow your theme — set it once, applied everywhere.
