Products
A directory of every Vesper product. Core accessibility suite, plus the utilities that sit alongside it. Use this as a quick jump board to overview pages, docs, and downloads.
Core suite
macOS App · Supporter
A desktop crawler that walks any site and produces a full WCAG 2.2 accessibility report - PDF, HTML, Markdown, Notion, or CSV. Configurable scan profiles, exclusions, suppressions, and detailed report mode for evidence-grade audits.
Chrome Extension · Free
A hover-to-inspect overlay for accessibility QA in real time. Tooltips show accessible name, role, tab order, ARIA state, font data, contrast, and image dimensions on every element you point at.
Web · Mac · iOS · Chrome · Free
A WCAG 2.2 contrast checker on four platforms. Web tool for quick checks, palette creator, color profiles, color-blindness simulation. Native macOS menu bar app and an iOS app for checking pairings on the go. A Chrome extension reads the real colors a site uses and checks their contrast in place - including a whole-page sweep that points at what fails - and Color Audit scans a site's colors for near-duplicates and contrast failures.
Reference · Free
Twenty-six plain-language accessibility guides. Heading structure, alt text, color contrast, link patterns, PDFs, neurodivergent-user considerations, and more. Linked from Vesper Audit reports and used standalone as a learning resource.
Utilities
macOS App · Beta · Free
A domain media archiver. Crawls one site breadth-first and downloads every PDF, image, audio file, and video into a clean per-site folder with a manifest CSV. Built for librarians and archivists capturing media off sites they don't host.
macOS App · Beta · Free
Responsive QA in three viewports at once. Loads any URL into mobile (390), tablet (768), and desktop (1920) panes side by side. Scroll, click, and navigate stay in sync. Built to replace bloated stand-alone responsive-QA tools with one focused app.
