Your content. Your team. Your independence.
A custom website with CMS is a site built entirely for your business, with an admin interface designed around your real workflows — not a tweaked WordPress theme or a limited SaaS platform. At Numinam, I work as an independent developer based in Brussels, building these sites on Laravel for teams that want to publish, edit and manage content without relying on a developer. The result: a digital tool your company owns, that scales with you, and makes your team independent from day one. I build these platforms for SaaS companies, real estate agencies, consulting firms and startups that have outgrown off-the-shelf solutions.
Why your current site is slowing you down
You call your agency to change a price.
One line on your pricing page. An email. A wait. An invoice. If every update goes through a developer, it's not your site — it's theirs.
Your marketing team waits 2 weeks to publish.
A new product page, a case study, an article. The content is ready. The decision is made. But the site won't be updated until the next sprint.
The generic CMS doesn't fit your processes.
WordPress, Webflow, Squarespace — these tools are built for everyone. Which means: perfect for no one. You adapt to the tool, not the other way around.
Multiple contributors, zero control.
Who can publish what? Who approves before going live? Who manages which language? Without fine-grained role management, everyone touches everything — or nothing at all.
The SaaS platform charges for every feature.
Multilingual: +X€/month. Extra users: +Y€/month. Storage: +Z€/month. The subscription cost grows with you — in the wrong direction.
You can't evolve the architecture.
Client portal, configurator, partner access, dynamic catalogue — your current platform wasn't built for this. Every new feature is a workaround.
A site built around your organisation.
Bespoke design — every screen validated before a single line of code.
No templates. No €49 theme stretched to fit. I design every page from scratch, for your brand, your users, your goals.
Wireframes, high-fidelity mockups, iterations — your team signs off at each stage. By the time development starts, there are no surprises.
A CMS built for your team — not for developers.
The admin interface is designed around your real processes: how you organise content, who approves what, which fields actually matter. A non-technical person can publish a full page in under 10 minutes.
Role management (editor, contributor, admin, reviewer), multi-level publication workflows, interface in the language your team works in.
Robust architecture — built to grow with you.
SEO baked in from day one (sitemap, structured markup, Core Web Vitals). Native multilingual. API integrations with your CRM, analytics tools, and internal systems. Security by design: access roles, automatic backups, HTTPS, GDPR compliance.
When you want to add a client portal or partner dashboard in 6 months — the architecture is already ready for it.
Training included — 3 sessions, your team takes the wheel.
I don't hand over a site and wish you luck. 3 training sessions included: CMS walkthrough, your team's real use cases, live Q&A. Plus bespoke documentation for your admin interface.
Goal: 3 weeks after launch, your team is fully independent. No exceptions.
9 countries. 1 back-office. Zero dependency on a developer.
Coddy — urban escape games running across 9 countries in Europe — runs on a bespoke back-office I built. Each country manager accesses their own dashboard, updates their adventures, adjusts availability. No developer. No ticket. No waiting.
The results: hundreds of thousands of players served, 90% of customer interactions automated, and page load times under 1 second. That's the logic I apply for every custom web development project: a CMS built around your organisation, not around a generic standard.

Honest comparison: which system for which situation?
No bashing. Just the criteria that matter for making the right call.
| Numinam bespoke | WordPress + plugins | SaaS platform | |
|---|---|---|---|
| Publishing autonomy | Full autonomy from day one | Possible with the right plugins | Limited to your plan's features |
| Role management | Tailored to your organisation | Partial, plugins required | Standard, not very configurable |
| Fits your processes | Yes — built around you | No — you adapt to WP | No — you adapt to the platform |
| Code ownership | 100% yours | Yours, but plugin-dependent | No — locked into the platform |
| 3-year cost | Fixed investment + optional maintenance | Growing (plugins, updates, hosting) | Recurring subscriptions that increase |
| Scalability | Architecture that grows with you | Possible but often expensive | Capped by the platform |

Two approaches. One deciding factor: who manages content?
This isn't a budget question — it's an organisational one. Choose the model that fits your team.
Questions I get asked about custom websites
How much does a custom website with CMS cost at Numinam?
A custom website with CMS starts from €16,000. This covers the full design process (wireframes, mockups, iterations), backend development, bespoke CMS, user role management, required API integrations, 3 training sessions and 3 months of post-launch support. The final price depends on project complexity: number of content types, role levels, advanced features (client portal, partner access, dynamic catalogue, configurator). A free 30-minute audit scopes the project and provides a precise estimate.
How long does it take to deliver a custom website at Numinam?
A custom website is delivered in 10 to 16 weeks depending on complexity. The project runs in 4 phases: audit and scoping (weeks 1-2), design and validation (weeks 3-6), development (weeks 7-14), launch and support (month 4+). This timeline includes client validation sessions and iterations. Projects with complex features — client portals, multi-country dashboards, configurators — may require up to 20 weeks.
Do you need technical skills to use the CMS delivered by Numinam?
No. The CMS I deliver is designed specifically for non-technical users. The admin interface is built around your team's real processes: fields match what the team publishes, labels are clear and jargon-free, workflows match the internal organisation. Someone who has never used a CMS can publish a full page in under 10 minutes after one training session. 3 training sessions are included in every project.
What is the difference between an Astro site and a Laravel site at Numinam?
The model choice comes down to one question: who manages content after launch? An Astro site (high-performance websites offering) is an ultra-fast static site where I handle content updates through a maintenance retainer — you send what you want published, I publish it. A Laravel site (custom website offering) includes a bespoke CMS: your team manages content with complete independence, without going through me. Both offerings include bespoke design, integrated technical SEO and a scalable architecture. The difference is organisational, not technical.
Who owns the code when Numinam delivers a custom website?
You do — entirely. At project delivery, I transfer full ownership of the source code to you. No annual licence, no platform subscription, no imposed hosting constraint. You can host the site wherever you choose, modify the code with your own team or another developer, and evolve the architecture without depending on me. The code is fully documented, and technical documentation is provided at delivery.
Is training included in a Numinam custom website project?
Yes. Every custom website project includes 3 CMS training sessions. These sessions are tailored to your team's real use cases: publishing articles, managing a catalogue, administering users, and so on. Bespoke documentation of the admin interface is also provided at delivery. The goal: 3 weeks after launch, your team is fully independent — without depending on me for day-to-day operations.
How does technical maintenance work after a Numinam custom website is delivered?
3 months of post-launch support are included in every project. During this period, I answer questions, fix any bugs and support the team's onboarding. After these 3 months, a technical maintenance contract is available from €200/month. It covers security updates, automatic backups, uptime monitoring and bug fixes. This contract is optional — you are free to manage maintenance internally or through another provider.
Is it possible to migrate from WordPress to a custom Numinam website?
Yes. I handle migrations from WordPress (and other CMS platforms) to custom websites. Migration includes transferring existing content (pages, posts, media), setting up 301 redirects to preserve existing SEO and verifying technical SEO post-migration. If the current WordPress site has specific features (WooCommerce shop, complex forms, integrations), these are analysed during the audit and rebuilt natively in the new architecture. Existing SEO is fully protected throughout the migration.
Why choose a proprietary CMS over an off-the-shelf solution?
A proprietary CMS is an admin interface built from scratch for a specific business — not a generic tool stretched to fit. Where WordPress imposes its post-and-page logic, and SaaS platforms cap features behind subscription tiers, a proprietary CMS adapts to the organisation that uses it.
The concrete advantages: fields that match exactly what the team publishes, role management mirroring the org chart, approval workflows aligned with internal processes, and zero dependency on third-party plugins or forced updates. The company owns the code, hosts it wherever it wants, and can evolve the architecture without platform constraints.
Your team deserves a tool built for them.
25 minutes. That's all it takes to map your needs, your CMS users and your organisation. You leave with a clear diagnosis: which model fits you, what the scope looks like, what to expect budget-wise.
