Open Source TypeScript Accessibility Tools

Thorium Reader is a free, open-source desktop application designed for accessible digital reading and e-book management. Built on the Readium Desktop toolkit, it supports EPUB publications and other digital reading formats. Users can import books from local directories or online catalogs using OPDS feeds. The application provides customizable reading layouts, typography adjustments, bookmarks, and navigation through tables of contents. Accessibility is a central priority, with support for screen readers such as NVDA, JAWS, and Narrator. Thorium Reader also supports publications protected with Readium LCP and includes multilingual interface localization. Available for Windows, macOS, and Linux, it delivers an advertisement-free reading experience without collecting personal reading data.

UUV is an open-source platform that automates accessibility testing for web. It helps development, QA, and accessibility teams detect accessibility issues early, improve software quality, and maintain compliance with standards such as WCAG, RGAA, RAWEB. The UUV Desktop Assistant allows users to inspect UI elements, verify accessibility properties, and automatically generate reusable Gherkin scenarios and accessibility assertions. Test execution produces detailed reports with errors, warnings, notices, and remediation guidance. The UUV Dashboard centralizes results from multiple projects, enabling teams to monitor accessibility metrics over time, identify regressions, compare executions, and track compliance progress through interactive reports. UUV integrates into CI/CD pipelines to support continuous accessibility testing throughout the software development lifecycle, reducing remediation costs while making digital services .
