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, updates itself with signed releases and needs no Composer or command line. Collections cover services, references and team, and Claude can build and change pages as drafts you approve.
Moving over
Moving from Drupal.
Kaleta has no importer for Drupal. For a business website the practical route is a rebuild: connect Claude, give it the addresses of your old pages and it builds each one as a draft from Kaleta sections, in your design system. You check the preview, publish, and add 301 redirects from the old addresses so links and rankings carry over.
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 and visitor texts translated into eight.
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.
