Tabvera lets you add your own reusable tabs to the WooCommerce single product page, alongside the native Description, Additional information and Reviews tabs.
Define your tabs once under WooCommerce > Tabvera Tabs and they show up on every product. It suits content you’d otherwise paste into each product by hand: shipping and returns, size guides, care instructions, warranty notes.
Each tab is a title plus a content box that accepts the same limited HTML WordPress allows in posts (links, lists, bold, headings) via wp_kses_post. Your tabs render after the native WooCommerce tabs, and you can toggle each one on or off without deleting it.
The code lives at github.com/wppoland/plogins-tabby if you want to read it, report a bug or suggest a tab feature.
wp_kses_post-sanitised HTML on save, and by default sanitises it again on output.woocommerce_product_tabs filter at a late priority, so native and third-party tabs keep their place.Tabvera does not connect to any external services. It makes no remote API calls, loads no fonts, scripts or styles from a third party, and sends no data off your site. Your tab definitions are stored locally in a single WordPress option (tabby_settings), with a version marker in tabby_db_version, and both are removed on uninstall. The admin and front-end CSS and JavaScript it loads are bundled with the plugin and served from your own site.
Tabvera is fully translatable and ships the tabvera.pot template. Translations are delivered by WordPress.org language packs from translate.wordpress.org, which is where Polish, German and Spanish are being contributed; the package itself carries no compiled translation files.
