Vercel's Toolbar toolkit continues to grow, offering enhanced developer and user experiences. New additions include tools for accessibility audits (WCAG 2.1 Level A and AA compliance checks), Open Graph previews for social media link cards, and an interaction timing tool to measure and optimize Interaction to Next Paint (INP). The toolbar can now be used in production via a zero-config Chrome extension, enabling evaluation of INP, layout shifts, accessibility, and feature flag overrides on live sites. Existing features like Comments, CMS integration, Layout Shift analysis, and Quick Links are also enhanced.
