Managed Service 09 / 17
Headless Managed Website
Take the website off life-support. Flat, fast, and almost nothing left to attack.
Go headless on Astro & Cloudflare — authored once, pre-built into flat files, served from the edge with media on R2, so most of the threat surface, maintenance and cost simply disappear. Prefer a familiar CMS? We build and fully manage those too.
What Headless Managed Website delivers
Headless on the edge
Static HTML/CSS/JS, no server or database at runtime, global edge delivery, instant Git rollback.
Or a standard CMS
WordPress, Drupal, Joomla, Wix or Webflow — designed, built, hosted and kept fast, secure and patched.
Fully managed
Secure & patched, SEO-ready, backed up and monitored — surprises engineered out.

SanityKPIs we move — measured, owned, reported
Every KPI is tied to a named owner and a target agreed up front — so this service is accountable to outcomes, not activity, for every stakeholder who consumes the value.
Capability Maturity — we walk you up the five levels
Operated at Level 5 · Optimising — self-improving, measured and owned. We track this rank and raise it over time. See the five levels →
Why this matters
Functional value, value-stream value — and why it can't be ignored.
Designs, builds, hosts and continuously manages a fast, secure, edge-served website — flat architecture with almost nothing left to attack.
The conversion-and-trust surface of the value stream: it is where demand becomes action, so every second of load time and every vulnerability is a direct tax on conversion and reputation.
A slow, fragile or breached site loses customers before they ever speak to you — and a single incident can cost more than years of the saving made by neglecting it. Your shop window is open 24/7; it cannot sit on life-support.
Production pedigree
The architecture we build on is trusted at global scale.
Headless on Astro & Cloudflare powers production sites for some of the world's largest organisations — sub-second, secure and edge-served. This is the proven architecture behind our builds, not a client list.
Served on
CloudflareOne data layer · measured & owned
Every service creates data — captured, measured, owned.
Headless Managed Website doesn’t just run — it generates signal. We land that data in one warehouse and turn it into live KPIs tied to a named owner, so performance is attributable and acted on, never trapped inside a single tool.

Retool
Apache Superset Platform-agnostic — we connect what you already use and add a warehouse only where it earns its place.
How we select technology
We choose technology last — for the outcomes it has to earn.
Never tech for its own sake. A tool joins the stack only where it measurably protects value, cuts cost or unlocks speed — fit to a designed system, owned where it counts, and measurable from day one. How we select technology →
Speed
Modern, edge-served stacks are sub-second. Slow surfaces cost conversion and SEO every single day.
Cost
Cut licence, hosting and per-task SaaS fees — pay for capability, not lock-in or idle enterprise tiers.
Security
Flat, edge architecture with almost nothing left to attack — fewer moving parts, smaller surface.
Ownership & no lock-in
Composable and self-hosted where it counts — you own the system, not rent someone else’s.
Measurability
Clean data and KPIs baked in — you cannot improve, automate or apply AI to what you cannot measure.
Fit to process
The right tool for a designed system — selected against process readiness, so it amplifies, not adds friction.
How we deliver · DMAIC
Every Headless Managed Website engagement runs on DMAIC.
Define the goal and its value, measure the baseline, analyse the real constraint, improve with a proven build, then control the gains — so results are predictable, repeatable and defensible, not down to luck.
Agree the goal, value, budget & timescale up front.
Baseline the KPIs above — current state, not guesswork.
Diagnose the real constraint and the solution needed.
Build the chosen solution; prove the uplift.
Lock in the gains; monitor and sustain them.
