What a VS Code verified publisher badge means, compared with Open VSX →
Audits HTML, JSX, Vue, Twig, Blade, ERB and Razor markup against the 24 WCAG 2.1 Level AA checks that 28 CFR 35.200 and EN 301 549 actually name - not WCAG 2.2.
Daily readings on both stores, taken by us. As of 25 Sept 2026.
Each bar is one day’s change in the store’s own counter. Open VSX counts a download on every update, so a day includes updates by people who already had it.
Positions observed daily on both stores. Neither store publishes this, and the two run separate search engines over separate catalogues.
