Websites used to be made up of individual HTML files. Every change to the text needed someone who could write code. A CMS separates content from design. The design is set up once as a template, and the content sits in a database. You log in, change some text or upload an image and click “Update”. The system automatically puts the page together in the right design.
The best-known CMS is WordPress. According to W3Techs, it runs on 39.6% of all websites (as of October 2026). The software is open source and free. There are also systems such as TYPO3, Joomla and Drupal. Website builders like Wix or Squarespace work in a similar way, but they're a subscription where the software and hosting are tied together.
For a business, that means independence. New opening hours, a holiday notice or a new team member can be online in a few minutes. You don't have to ask an agency for every little thing. Several people can work with their own logins and permissions, for example a colleague who's only allowed to write blog posts.
What to look out for:
- Ease of use: have someone show you the system before you decide. Anything that's a hassle day to day simply won't get done.
- Maintenance: a CMS needs regular updates, otherwise security vulnerabilities open up.
- Extensibility: a contact form, multiple languages or a shop should be possible later without rebuilding everything.
- Independence: with open-source systems like WordPress, you can switch hosting provider and agency. With website builders, moving is often difficult.
We build WordPress websites so that you can edit the text and images yourself afterwards.
A physiotherapy practice in Zug has a WordPress website. In summer, one of the therapists is off for three weeks. The practice manager logs in one evening, opens the “Team” page and adds a short note. Then she adjusts the opening hours for the holiday weeks in the block editor. Ten minutes later, everything is online, with no email to the agency and no invoice. The design stays exactly as it was, because the CMS only swaps out the content.
