Kaleta vs. Drupal.
Drupal is built for complex, structured content and large organisations. Kaleta is built for business websites that one person – or Claude – can run. Both are open source; here is where each one fits.
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 Drupal if.
- you model complex content with many types, relations and views
- you need fine-grained roles, editorial workflows and approvals
- you run a large multilingual site with translation workflows
- you have Drupal developers or an agency that maintains the site

Drupal
Contributed AI modules with several providers, also offered in Drupal CMS; MCP through contributed modules.
Design system
Kaleta
Colours, fonts and spacing as tokens, shared classes and components, W3C Design Tokens export.
Drupal
Theme-based; tokens and components depend on the theme and its build tooling.

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.

Drupal
Excellent multilingual support in core, with dozens of languages.
Backups and updates
Kaleta

Drupal
Core and modules are updated with Composer, usually by a developer; automatic updates are available for some setups.
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.
Drupal
Efficient with good caching; depends on the theme and modules.
Extending it
Kaleta

Where Drupal is stronger
Structured content at scale.
Content types, fields, views, permissions and translation workflows make Drupal a platform for large sites with many editors and integrations. With a development team behind it, there is little it cannot model.
Where Kaleta is stronger
A business website without a dev team.
Kaleta installs over FTP, installs security releases by itself and takes new signed versions in one click from the admin, and needs no Composer or command line. Collections cover services, references and team, online booking and forms with calculators are built in, and Claude can build and change pages as drafts you approve.
Moving over
Moving from Drupal.
The Drupal importer reads a Drupal 9, 10 or 11 site through its JSON:API: articles come in as news with their images, tags and authors, basic pages as pages, and every old address gets a 301 redirect. Published content needs no sign-in; for unpublished content you type a token once and it is never stored. A preview shows counts and warnings first. Blocks, menus, views, the theme and comments do not come across – connect Claude and it reworks each page as a draft from Kaleta sections, in your design system. Before you switch the domain, the migration report checks every old address against the new site.
FAQ
Questions from Drupal users.
Can Kaleta replace a large Drupal platform?
Usually not. If you rely on complex content models, editorial workflows or many integrations, stay with Drupal. Kaleta fits business websites with services, references, team, news and enquiries.
Is Kaleta multilingual?
Yes. Each language version has its own pages and addresses, with around forty site languages, regional versions and Arabic written right to left; visitor texts are translated into 12 languages.
Do I need a developer to run Kaleta?
No. Installation, updates and backups are handled in the admin, and the look is set in the design system or by Claude.
