FAQ

Short answers to the questions people ask most. Each answer links to the page with the details.

General

Is Uncoder free?

Yes. Uncoder is free and open source (GPL). There is no account to create and no tracking. Download it from uncoderbuilder.com (opens in a new tab). Optional AI features use your own AI accounts and keys, which you pay to those services directly.

What do I need to run it?

WordPress 6.6 or newer and PHP 8.0 or newer, and a current browser for editing. See Installation & requirements.

Does it work with my theme?

Yes, Uncoder works with any theme. Its pages use your theme's header and footer until you build your own in the Theme Builder. For pages without the theme's header and footer, use the page template Uncoder Canvas (no header/footer). If you need a theme, the download page (opens in a new tab) also offers Uncoder, a free companion theme, but the plugin does not require it.

How do I update Uncoder?

Like any other plugin: new versions appear under Dashboard → Updates and on the Plugins screen, with an Update now link. See Update Uncoder.

Do I need to know how to code?

No. You build pages by dragging widgets onto the canvas and changing settings. If you do know CSS, you can add it to an element, a page or the whole site. See Custom CSS & attributes.

Can I still use the WordPress block editor?

Yes, page by page. Pages you build with Uncoder open in Uncoder; all other pages keep using the block editor or the classic editor. You choose which content types can use Uncoder in General settings, and you can hand a page back with Switch back to the WordPress editor.

What happens if I deactivate Uncoder?

Nothing is deleted. Pages built with Uncoder show a plain version of their text and images, without the design, and the design comes back as soon as you activate Uncoder again. Deleting the plugin also keeps your data, unless you turned on Remove all data on uninstall. See Advanced.

Can I move my site from Elementor?

Yes. Settings → Import & export → Import from Elementor rebuilds Elementor pages and templates as Uncoder designs and can bring over Elementor's global colors and fonts. Elementor's data is left untouched. See Import from Elementor.

AI

Do I need AI to use Uncoder?

No. Everything works by hand. AI is optional.

Do I need an API key to connect Claude or ChatGPT?

No key from Anthropic or OpenAI is needed in WordPress. The AI app works with your own Claude, ChatGPT or Cursor account and connects to your site over MCP. For apps without sign-in, you create an Uncoder API key on your site. See AI & MCP overview.

The AI buttons inside the editor are different: AI writing needs your Anthropic API key, and AI images an OpenAI-compatible key.

Can an AI break my site?

It can only do what you allow: each connection acts as a WordPress user with the permissions you choose, deleting needs a confirmation, and changes to pages, templates and the Design System can be undone from the activity log. You can switch all AI access off with one switch. See Security & privacy.

Does my content go to the AI company?

Only when you use AI. A connected AI app reads the parts of your site it needs for your request and sends them to its provider as part of your conversation. AI writing sends the text of one field when you click an AI action. See What data goes where.

Speed and SEO

Does Uncoder slow down my site?

Uncoder loads only the styles and scripts of the widgets a page uses, loads images lazily, and loads videos and maps only when they are needed. See Performance.

Does it work with caching plugins?

Yes. After changing the Design System or a template, clear your cache. See Caching plugins.

What about SEO?

Uncoder pages use real HTML headings, links and image alt text. Uncoder also adds structured data for your business, blog posts, FAQs and breadcrumbs, and works alongside SEO plugins such as Yoast SEO and Rank Math. Titles and meta descriptions are set in your SEO plugin. See Business & SEO.

Are Uncoder pages accessible?

Uncoder helps: the editor's Checks panel finds missing alt text, empty links and buttons, heading problems, low contrast and more. See Accessibility checks.

Teams and clients

Can clients edit texts without breaking the design?

Yes. Give their role Content only in Settings → Access & roles. They can change texts, images and links, but not add, move or restyle anything. See Roles & access.

Can several people work on the site?

Yes. If two people open the same page, the editor warns that someone else is editing it. You can leave notes on elements for each other, and every save is kept in the page's history.

Sites and content

Can I build a multilingual site?

Yes, with WPML or Polylang. See Multilingual.

How do I move a site to another server or reuse a design?

Export a site kit and import it on the other site. To reuse single templates, export them from the Theme Builder. See Export & import templates.

Where are my pages stored?

In your WordPress database, like any other page. Uncoder also keeps a plain HTML copy of each page's content, which is what shows if Uncoder is ever deactivated.

Where do I get help?

Start with Troubleshooting. If you are still stuck, email avi@uncoder.co and include the System info report.
