Kaleta vs. WordPress.
WordPress can do almost anything – with the right plugins. Kaleta does what a business website needs out of the box, and Claude can build it for you. Here is an honest comparison, including when WordPress is the better choice.
Choose Kaleta if.
you build business websites: services, references, team, news, bookings and enquiries
you want Claude to build the site and help run it – as drafts, within limits you set
you want the essentials built in and tested together, not a stack of plugins and subscriptions
you want the site on your own hosting, free and open source
Stay with WordPress if.
- you need an online shop, memberships or online courses
- you rely on a specific plugin or a large theme library
- your team and your clients already know WordPress well
- you need a large developer and hosting ecosystem around the site
Side by side
Feature by feature.
Kaleta
WordPress + page builder + plugins
Licence and cost
Kaleta
GPL-2.0-or-later, free. No paid tiers or per-site licences.
WordPress
Core is GPL and free. Page builders and many plugins are freemium or paid yearly.
Visual builder
Kaleta
Built in: 46 elements, 40 ready-made sections, styles per screen size and hover.
WordPress
Through a plugin (Elementor, Divi, Breakdance…) or the block editor. Very mature, with large template libraries.
Building with AI
Kaleta
Claude connects over MCP with your account’s permissions or less: drafts, signed previews, guardrails, undo of a whole session, scheduled runs.
WordPress
Depends on the stack: builder-specific AI features or third-party MCP plugins.
Design system
Kaleta
Colours, fonts and spacing as tokens, shared classes and components, W3C Design Tokens export.
WordPress
Global styles in the block theme or the page builder; varies by plugin.
Forms, booking, SEO, statistics
Kaleta
Built in: multi-step forms and quote calculators, online booking, sitemap, structured data, llms.txt, 301 redirects and self-healing links, cookie-free statistics, Google and CRM connections.
WordPress
Usually separate plugins (for example a form plugin, an SEO plugin, a redirect plugin, analytics).
Languages
Kaleta
Language versions built in: around forty site languages, regional versions and Arabic written right to left; visitor texts translated into 12 languages.
WordPress
Through multilingual plugins, often paid, with many languages.
Backups and updates
Kaleta
Automatic database backups, copied off the server once you add an FTPS or S3 target; signed updates on the Latest or Stable channel, security releases install on their own, the old files come back if an update fails.
WordPress
Core updates automatically; plugins, themes and backups depend on what you install and on the host.
Page weight
Kaleta
Clean HTML and CSS only for the elements on the page; the only third-party script, Leaflet for maps, is served from your own site and loads after a click.
WordPress
Depends on the theme, builder and plugins; builder pages are often much heavier.
Extending it
Kaleta
Built-in modules you switch on and off, webhooks, the Claude connection (MCP), and add-ons through a versioned extension API – switched on by an administrator who trusts them.
WordPress
Tens of thousands of plugins and themes for almost any need.
E-commerce, memberships, courses
Kaleta
Not included. Online booking of appointments is built in, without payments.
WordPress
WooCommerce and many membership and LMS plugins.
Hosting
Kaleta
Any hosting with PHP 8.3+ and MySQL 8 / MariaDB 10.6+; install over FTP in about ten minutes.
WordPress

WordPress
One of the largest open-source communities on the web.
Checked in October 2026 against Kaleta 3.31.1. Other systems change quickly – check the current state of the tools you use.
Where WordPress is stronger
An ecosystem for everything.
Tens of thousands of plugins, WooCommerce, memberships and courses, a huge community, a large pool of developers and hosting built around it. If your site depends on any of that, WordPress is the right tool – and that is fine.
Where Kaleta is stronger
One system, no plugin pile.
Builder, design system, forms with calculators, online booking, SEO, redirects, statistics and backups come as one tested whole, updates are signed and security releases install themselves, and Claude can build the site with you – safely, as drafts you approve.
Moving over
Moving from WordPress.
The WordPress importer brings posts, pages, categories, tags, menus and images, the SEO data from Yoast, Rank Math or SmartCrawl, custom post types and fields, WooCommerce products as a product catalogue, and Polylang or WPML translations as linked language versions. A preview shows counts and warnings before anything is imported, and every old address gets a 301 redirect. Comments, user accounts and page-builder layouts do not come across – rebuild those pages in the builder, or ask Claude to do it from the old page. Before you switch the domain, the migration report checks every old address against the new site.
FAQ
Questions from WordPress users.
Will my Elementor or Divi layouts come across?
No. The importer brings the content, but layouts made with a page builder are not converted. Rebuild them from ready-made sections, or give Claude the old page and let it build a draft.
Will I lose my search rankings?
Kaleta creates 301 redirects from every old address to its new page, so links and rankings carry over. The migration report checks every old address against the new site before you switch the domain.
Can I add plugins?
Yes, as add-ons. Since Kaleta 3.0, code from other developers can hook in through a versioned extension API. An administrator switches an add-on on after confirming they trust the code, and an add-on that fails switches itself off. There is no add-on marketplace – most of what a business website needs, such as forms, booking, SEO and backups, is built in and tested as a whole.
Can I take my content elsewhere later?
Yes. The site export packs your pages, news, collections and media in an open format – JSON with a description of every table, plus the media files.
