How much does a project cost, and how long does it take?

We define the scope and estimate the effort. Then we give you a fixed price and timeline. We bill ongoing work such as operations or CTO as a Service by the hour or as a monthly retainer.

Who owns the code, domain and Cloudflare account?

That’s your choice. If you prefer, we manage your domain and Cloudflare account and handle operations for you. Or you keep everything in your own hands and give us the access we need. The code is yours in every case and can be moved at any time.

Where will our data be hosted, and how do you address the GDPR?

We use Cloudflare for hosting. We determine the processing location for the specific services and data involved. Together, we review data flows, access and any required data processing agreements. We don’t make a blanket promise of Germany-only hosting.

What happens after launch?

We can handle operations. Technical updates and new features are also possible. We agree on the scope before launch. If you want to run the project yourself, we plan the handoff with you.

Can you migrate our existing website to Cloudflare?

Yes. We start by reviewing code, content, data and integrations. Then we determine what can move to Workers and Static Assets and what needs to change for the migration.

Do you work remotely?

Yes. We discuss requirements, share progress and review results together over video calls.

Build. Launch. Run.

We build websites, web apps and apps, connect them to your tools and run them after launch. We move existing systems to Cloudflare®. After a security incident, we help with cleanup and hardening.

Cloudflare

Built on Cloudflare

Ruxiom runs on Cloudflare, from hosting and data to DNS and domains in the same account. Internal systems sit behind Cloudflare Access. We run most client projects the same way.

Cloudflare Workers
Backends, APIs and server-rendered pages.
Static Assets
Serving static pages from any framework that runs on Cloudflare, for example Astro or Next.js.
D1
Relational data for admin tools, forms and QA workflows.
Workers KV
Cache for configuration, team settings and processing state.
R2
Storage for screenshots and uploads. Media and test results are stored there too.
Durable Objects
Shared workspaces and QA workflow coordination in real time.
Email Service
Transactional email and application notifications.
Email Routing
It forwards addresses on your domain to existing mailboxes without running a mail server. We use it in production for clients.
Turnstile
Bot protection for public forms.
Cron Triggers
Scheduled cleanup, data reconciliation and billing.
Images
Image optimization for delivery.
DDoS protection
Mitigation of volumetric attacks on websites and APIs, active on every Cloudflare zone.

Rate Limiting
Throttling requests to public endpoints.
Bot protection
Super Bot Fight Mode against automated traffic, configurable on the Pro plan and above.
Cloudflare Access
A sign-in step in front of internal tools and staging environments so that only approved people have access. We use it in production ourselves and for clients.
Cloudflare Tunnel
Connections to servers without open ports.
CDN
Delivery and cache rules for pages, images and fonts.
DNS
DNS zones with DNSSEC and email records (SPF, DKIM, DMARC).
