Score: 7.3/10 (Innovation: 7, Technical: 7, Documentation: 8, Utility: 7)

Outloud is an open-source PDF accessibility checker that runs on macOS, Linux, and Windows via CLI, CI, and a local browser app. It combines conformance checks (PDF/UA-1, WCAG 2.2) calibrated to agree with veraPDF, with novel semantic rules that catch issues validators miss, such as meaningless alt text or empty table headers. Every finding includes evidence, relevant standards, and a suggested fix, making it practical for developers and accessibility auditors.

Target audience: backend devs, devops, accessibility auditors, technical writers
