Free here: Lints the .opf file you have open and names every missing, mistyped or self-contradicting accessibility metadata value, with the exact line to paste.. In the editor: Scans every .opf in a whole catalogue folder in one run and writes a dated pass/fail report you keep and hand to a distributor. — that part asks for a licence key.

$29 once · one licence key per person or team seat · An EPUB production freelancer bills $50 to $95 an hour.

Same engine as the VS Code extension, byte for byte.
