Small browser tools for
everyday website checks.
The A1 Local extension set covers accessibility, typography, color sampling, map setup, page performance, full-page screenshots, source checks, image workflows, search actions, reader mode, and busy tab sessions. Each tool is built to do one job clearly, run after you choose to use it, and keep working data in your browser.
Twelve focused tools, not a bloated suite.
These are practical browser utilities for common website work: quick audits, CSS and color checks, map setup clues, performance snapshots, full-page screenshots, source inspection, image collection, search actions, reader mode, and tab cleanup. Each tool is kept focused so it is easy to understand, run, and support.

These extensions do not send scan results, saved samples, tab workspaces, image lists, reading lists, or browsing history to A1 Local. Where an extension stores settings or recent activity, it uses browser local extension storage.
