Bolt CMS: sovereignty score and 8 European alternatives

Bolt is an open-source content management system for websites, written in PHP and built on the Symfony framework. The software is installed by the organisation using it; the project website says it can also run in headless mode alongside a static site generator. The source code is available under the MIT licence. The project was founded by an individual developer and is maintained by a core team and a community.

Commercial development is backed by Two Kings, a web agency in The Hague. Because Bolt runs on the organisation's own servers and the project has no provider-operated cloud, the organisation decides where its data is stored. For a European organisation this is an open, auditable option without a US parent company, although hosting, security updates and the Symfony dependencies remain the user's responsibility.

Why digital sovereignty matters with Bolt CMS

Bolt CMS is headquartered in NL and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Bolt CMS scores best on data residency.

Bolt CMS is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Bolt CMS together with your other vendors and gives a total score, a heatmap and the main risk drivers.
