TDF Developments builds TDF Image Alt Scanner, a WordPress plugin that finds and fixes missing image alt text for better accessibility, SEO, and WCAG…
TDF Developments is an independent UK studio that builds small, single-purpose WordPress plugins rather than broad, all-in-one toolkits. Its current product is TDF Image Alt Scanner, a plugin that scans an entire WordPress site — posts, pages, custom post types, the Media Library, and WooCommerce product galleries — to locate images with missing, decorative, filename-only, or otherwise low-quality alt text. Results are shown in a sortable, filterable table with a compliance-score dashboard, scan history, inline editing, CSV export, and support for Gutenberg image, cover, and gallery blocks. The free tier covers up to 500 images per site. A paid Pro tier, sold through Freemius checkout, removes the image cap and adds AI-generated alt text suggestions (using the site owner's own API key for Anthropic Claude, OpenAI, or Google Gemini), scheduled re-scans with email or Slack reports, branded WCAG 2.1/2.2 PDF compliance reports, support for 30+ languages, WooCommerce-aware prompts, and integrations with popular page builders (Elementor, Beaver Builder, Bricks, Divi). The plugin is GPL-licensed, requires WordPress 6.0+ and PHP 8.1+, and the studio markets it as privacy-first: no data leaves the site unless the user explicitly wires in their own AI API key.
