Wagtail agency • Brussels
Wagtail agency at the heart of Europe
KernWeb is the web division of KERN-IT, a Belgian agency based in Brussels. We design, migrate and host custom Wagtail websites since 2015, for organisations in Belgium, France, Luxembourg, Switzerland and across Europe.
Why Wagtail
Wagtail is an open source CMS built on Django (Python), the same technical foundation as the business platforms KERN-IT has been building since 2012. It powers organisations that cannot afford to get it wrong.
- Google, NASA (JPL), the UK's NHS and the French State run on Wagtail.
- Security by design: no pile-up of third-party plugins, a smaller attack surface.
- Native multilingual: essential to communicate at European scale.
- You own the code: no licence, no dependency on a vendor.
- Accessibility built in: Wagtail targets WCAG 2.2 AA, designed in from the start rather than bolted on afterwards.
- Scales without pain: from a few pages to thousands, without the growing pains of plugin-based CMSs.
- For developers and editors alike: the StreamField interface keeps editing simple, the Django architecture keeps the code solid.
What our Wagtail agency does
Custom Wagtail websites
A unique design and page templates built for your organisation, on a clean, durable Django architecture.
Migration to Wagtail
Coming from WordPress or an ageing CMS? We migrate your content to Wagtail without losing your search rankings.
Hosting, support & training
Managed hosting, security updates, support and training so your teams can edit content on their own.
And also: audit of an existing Wagtail site, custom integrations (CRM, payment, API), and taking over and maintaining legacy Wagtail projects.
At the heart of Europe
Brussels is the de facto capital of the European Union. Our offices are ten minutes from the European Quarter, at the crossroads of the Belgian, French, Luxembourg and Swiss markets.
The agencies in the Wagtail core team are in the UK, the Netherlands, Sweden, the USA and Iceland. KERN-IT brings that Wagtail expertise to the heart of French-speaking Europe: projects run remotely or on site, with intra-EU reverse-charge invoicing for companies outside Belgium.
The largest French-speaking Wagtail reference is the French State itself: DINUM made it the foundation of Sites Faciles, the CMS for government websites (DSFR design) — around fifty administrations and half a million visits a month. Sites Faciles is reserved for central government: local authorities, universities, associations and companies that want the same solidity can rely on a French-speaking Wagtail agency. That's what we do.
Ten years of engineering behind every site
KernWeb draws on KERN-IT's track record: 10+ years, 50+ clients and 100+ delivered projects, rated 5 stars on Google. Our team has practised Wagtail since 2015 and maintains a glossary and detailed comparisons about it.
Wagtail is not a CMS we discover on your project: it is our specialty, not one option among many. Every site is built 100% custom, no template.
Frequently asked questions about our Wagtail services
A Wagtail agency designs, builds and maintains websites on the Wagtail CMS rather than on template-based solutions. At KernWeb, every page template and content block is custom-built, on a clean and maintainable Wagtail architecture.
