You can install any plugin, theme, or page builder of your choosing on a 10Web-hosted website. The general rule is: if it's compatible with WordPress, it will work on our hosting.
Where to install them
- From WordPress admin — go to Plugins → Add New Plugin (or Appearance → Themes → Add New Theme) and install as you would on any WordPress site.
- From the 10Web dashboard — open the site, expand Advanced in the sidebar, and go to Plugins & themes to manage what's installed without leaving the dashboard.
Before you add one, check the not-recommended list
10Web's hosting already includes its own caching, backup, image-optimization, and security systems. Certain categories of third-party plugins — caching, backup, image optimization, speed/performance, and a few others — can conflict with these built-in systems and slow your site down instead of speeding it up. See the full, categorized list in Plugins Not Recommended by 10Web before installing.
The limitation on websites built with the 10Web Agentic Website Builder
If your website was generated with 10Web's AI Website Builder (rather than built manually with a classic WordPress theme), the rule above still applies — you can install any plugin or theme — but with an important caveat specific to that builder:
- The pages you see and edit in the AI Website Builder are not stored as regular WordPress page content. In wp-admin, these pages exist only as placeholders (for example "Home — WVC Editor"); the actual design and content are rendered by 10Web's own front-end application. Editing them directly in the WordPress page editor, or redesigning them with a third-party page builder (Elementor, Divi, Beaver Builder, etc.), will not change what visitors see on the live site.
- Switching the site away from its built-in theme, or editing the theme's files directly in wp-admin, is not recommended on an AI-built site — it can break the layout the AI Website Builder generated. Installing and activating a plugin is generally safe; changing the active theme or editing pages directly in WordPress is not.
A third-party plugin that adds a standalone feature (a form, a chatbot widget, an analytics tag, etc.) is usually fine. A third-party page builder or theme meant to redesign your existing pages will not work as expected on an AI-built site, because that site's design is managed by the AI Website Builder itself, not by the active WordPress theme or page content.
If you're unsure whether a specific plugin, builder, or theme is safe to add to your site, contact 10Web support before installing, and take a backup first from Manage → Backups so you can roll back if needed.
