Replatform WordPress to Astro
Take WordPress headless on Astro — sub-second, secure, and almost nothing left to attack.
Keep the content and editing you know; lose the bloat, the plugins and the attack surface. We re-platform your WordPress site to a fast, static Astro front end on Cloudflare — with or without Sanity as a modern headless CMS — faithful to the design, faster and far safer.
Sentry's WordPress to Astro migration re-platforms your site to a fast, static Astro front end on Cloudflare — with or without Sanity as a headless CMS — keeping the design and content faithful while removing the plugins, the PHP and most of the attack surface.
What actually changes
Your design is carried across exactly as it is. A redesign is a separate project, quoted separately, and only if you want one.
Website replatforming
Off WordPress. Onto Astro, served from Cloudflare's edge.
An ageing content management system costs you three ways at once: maintenance and licences you keep paying, a break-in risk you carry, and slow pages that lose the visitors your ads and search already paid for. Replatforming removes all three, keeps your design, content and addresses, and leaves a site ready for what comes next.
Why replatformWhat staying on WordPress costs you
The valueWhat replatforming returns
Break-in risk you carry
Every plugin runs on your server with reach into your database, maintained on someone else's schedule. Of the WordPress vulnerabilities disclosed in 2025, 91 per cent were in plugins and 9 per cent in themes. Attackers use AI to find unpatched sites within hours. Staying put means out-patching that, every week, forever.
Attack surface removed
The plugin and theme layer stops existing, so effectively every one of those vulnerabilities has nowhere to land. No admin login. No database. No code running on request.
Debt that blocks upgrades
Page builders, child themes and abandoned plugins each pin a version. One core update breaks a plugin, the plugin has no maintainer, and the upgrade stops happening at all.
Nothing to carry forward
Components to keep compatible go from dozens to zero. Content, design and web addresses come across. The debt is written off at migration.
A bill that repeats every month
Plugin licences, hosting that climbs with traffic, monthly patching hours, out-of-hours emergencies. You pay it whether or not anything improved that month.
Maintenance cost removed
Zero plugin licences. Zero patching hours. Static hosting that does not climb with traffic. The line is removed, not trimmed.
Visitors lost before the page loads
A WordPress page loads a theme, a page builder and a stack of plugin scripts before the visitor sees anything. Traffic your advertising and search budget already bought leaves before the page finishes.
Measurably faster pages
At least a 20 per cent improvement in measured performance where the current measurement leaves room for it. Proven on the same test, before and after.
No record, and slow recovery
Changes made in the WordPress admin leave no record of who changed what. When it breaks, recovery is a restore from a backup of unknown age, by whoever still remembers the setup.
Versioned, with one-step rollback
Every change versioned, reviewed and tested before release. Rollback to any previous version in one step. Recovery in minutes.
AI cannot reach your content
Your content is locked in a database behind a login, in markup built for a browser and not for an agent. An AI tool cannot act on what it cannot read.
AI and agentic foundations
Content becomes machine-readable and deployment becomes something software can run. Module 01 of the roadmap below, and the prerequisite for every module after it.
Our own site runs on it. Every page sits in Google’s “good” band for speed, on mobile and desktop, measured 17 September 2026.
5 hours
Median time from a WordPress vulnerability being made public to it being exploited at scale, because attackers now use AI to find and exploit them automatically. Of the WordPress vulnerabilities disclosed in 2025, 91 per cent were in plugins and 9 per cent in themes. Only six were in WordPress itself. Patchstack · State of WordPress Security 2026
How we replatform
01
Discovery
We map the current site, its content, integrations and traffic, and agree what must be preserved.
02
Plan
A written migration plan: scope, page-by-page mapping, redirects, risks, and the measured baseline.
03
Approval
You approve the plan and the agreed targets. No build starts without it.
04
Replatform
Build, test and launch, then re-run the same tests and hand you the before-and-after.
Typical outcome: at least a 20 per cent improvement in measured performance where the current measurement leaves room for it, and the plugin and theme attack surface removed entirely. Proven on the same test, before and after.

Replatforming is module 01, deliberately first: a fast, secure, agent-readable website is the asset every later module reads from and acts on. Each module stands alone, and there is no obligation to take the next.
What Replatform WordPress to Astro delivers
Faithful, faster
Pixel-faithful rebuild on Astro — typically sub-second, with SEO and structure preserved and improved.
With or without Sanity
Keep editing in a modern headless CMS (Sanity), or go fully static — your workflow, your call.
Flat & secure
Edge-served on Cloudflare — no PHP, no plugin attack surface, almost nothing left to attack.
Representative stack
KPIs 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 4 · Quantitatively Managed — measured, predictable 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.
Re-platforms a WordPress site to a static, edge-served Astro front end (optionally with Sanity as a headless CMS) — faithful to the design, stripped of plugin bloat and attack surface.
The conversion-and-trust surface, rebuilt: every second of load time and every vulnerability removed is a direct gain in conversion, SEO and reputation — without losing the content you already own.
A plugin-heavy WordPress site is the most-attacked software on the web and a silent tax on speed and SEO. Every month on it is conversion lost to slow pages and a breach waiting on an unpatched plugin.
One data layer · measured & owned
Every service creates data — captured, measured, owned.
Replatform WordPress to Astro 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.
Data warehouse
KPIs, dashboards & apps
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 Replatform WordPress to Astro 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.
FAQ
Common questions
Will the site still look the same after migrating from WordPress?
Yes — the rebuild is pixel-faithful, with SEO and structure preserved and improved rather than recreated. A migration that also redesigns the site makes it impossible to tell which change caused a drop in performance, which is why Sentry keeps the two apart.
How will our team edit the site without WordPress admin?
Either through Sanity, a modern headless CMS that gives editors a clean authoring experience, or fully static if the content rarely changes. It is your workflow and your call — the migration does not force an editing model on a team that already has one that works.
Why move off WordPress at all?
A plugin-heavy WordPress site is the most-attacked software on the web and a silent tax on speed and SEO. Every month on it is conversion lost to slow pages and a breach waiting on an unpatched plugin. Astro on Cloudflare removes the PHP and the plugin surface entirely.
How much faster will the site actually be?
Typically sub-second, because there is no server or database assembling the page when a visitor arrives — the HTML already exists and is served from Cloudflare's edge. The gain comes from the architecture rather than from tuning, which is why it holds under load.
What happens to our search rankings?
Content, structure, redirects and SEO are carried across deliberately as part of the migration, and page speed improves, which search engines reward. The risk in any re-platform is an incomplete redirect map, so that is built from what actually exists rather than from what the sitemap claims.
Do we lose anything by leaving WordPress?
You lose the plugins, which is usually the point — but if a plugin is doing genuine work, that capability is identified in Discovery and rebuilt rather than dropped. Migrating first and discovering the gap afterwards is the failure mode this avoids.
