WordPress runs more than 43% of the web on PHP and MariaDB, and its plugin ecosystem keeps people on it long after they have outgrown the editor. The software is free under the GPLv2 and self-hostable anywhere, including on European infrastructure. The hosted WordPress.com service is a separate commercial product from Automattic in the United States.

About Kirby
Kirby is a German file-based CMS that stores content in plain files and folders, with no database to install, back up, or break. Sites deploy by copying files, version cleanly in Git, and stay fast under load, which is why designers and developers have made it a quiet favorite since 2012.
The admin Panel is fully customizable through blueprints: editors see exactly the fields their content needs, nothing more. Kirby renders through classic PHP templating or runs headless via its API, and a rich plugin ecosystem extends both. Licensing is refreshingly simple: a one-time payment per site, three years of updates, no subscription.
Key features:
- No database, content lives in files and folders you can version in Git
- Customizable Panel with blueprints shaping the exact editing interface
- Headless or templated output from the same content
- One-time license of 99 euros per site, no subscription lock-in
- Unlimited free local installs for development and staging
- Plugin ecosystem with an official directory and stable APIs
- Free licenses for students, educators, and selected showcase projects
Kirby is developed by Content Folder GmbH & Co. KG near Heidelberg, Germany, and proudly carries its Made in Europe branding. As a self-hosted product your content never touches a third-party cloud, and the source is publicly auditable even though the license is commercial.
Ideal for design studios and developers replacing WordPress on client sites that need speed, clean content modeling, and zero database maintenance.
Why choose Kirby over WordPress?
The decisive argument is data jurisdiction. WordPress is headquartered in the United States, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
Kirby removes that overhead. As a Germany-based provider, it operates under EU GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single jurisdiction that can change the rules without warning.
