What Zinn® SEO does for developers and your data, and which of it is free.
Developers
REST API and WP-CLI — Every setting and every page's SEO fields can be read and changed through the REST API and with wp zinn-seo commands.
Hooks and a typed PHP API — Documented actions and filters, and zinn_seo() for themes and other plugins.
One feature list — The plugin's own list of what it does drives its Plans screen, its documentation and its AI tools, so they cannot disagree.
Your data
Clean uninstall — Deleting the plugin removes every setting, field, table and role it created, unless you choose to keep your data.
Copy settings to another site — Export your settings to a file and import them on another site, with a preview of every change before anything is applied.
Free or Pro
Everything here is in the free edition.
