Joomla → Astro

There is no Joomla deadline. There is a running cost, and it rises every year.

Joomla 5 upgrades to Joomla 6 in place, and Joomla has published support dates running to 2029. Nothing forces a decision here, and that is the honest starting point. What a Joomla site actually costs is the platform plus every extension bolted to it — each maintained by somebody else, on their schedule, each a separate way into the site and a separate thing that can block the next upgrade. We re-platform the front end to a static Astro build on Cloudflare: the same content, the same URLs, served from the edge. Editors can keep Joomla and author exactly as they do now, or the platform can be retired altogether.

What Joomla → Astro delivers

Editors can keep Joomla

Joomla 4 and later expose a core web services API covering articles, categories, fields and menus. Astro reads that and builds the pages, so the authoring your team already knows is untouched.

Faithful re-platform

Content, structure, URLs and redirects carried across, so rankings and inbound links survive the cutover.

The extension list stops growing

Every third-party extension is a separate maintainer, a separate update and a separate way in. A static build has none of them in the request path, so there is nothing to patch on a Tuesday.

The page arrives faster

A visitor who waits is a visitor who leaves. A page built once and served from the edge starts rendering immediately, with no PHP execution and no database query standing between the click and the content.

We name what is rebuilt

Forms, member logins, search, galleries and anything an extension renders at request time are rebuilt, not converted. You get that list before you commit, not after.

Version support — the published end-of-life dates

What is still supported, and what has already stopped.

Joomla 2.5

Unsupported. No fixes of any kind since end of life.

End of life: 31 December 2014

Joomla 3.x

Unsupported by the project. Continued security cover after this date is a paid third-party arrangement, not part of Joomla.

End of life: 17 August 2023

Joomla 4.x

Unsupported. Regular bug fixes ended in October 2024 and security fixes ended a year later.

End of life: 17 October 2025

Joomla 5.x

Released 17 October 2023. Regular bug-fix support ends 13 October 2026; security fixes continue to the date shown.

End of life: 12 October 2027

Joomla 6.x

Released 14 October 2025. Current. Regular bug-fix support ends 17 October 2028; security fixes continue to the date shown.

End of life: 16 October 2029

Dates are taken from Joomla's own published sources — the project roadmap at developer.joomla.org for Joomla 5 and 6, and the Joomla! CMS versions chart on docs.joomla.org for the earlier releases. Read them as context, not as a threat: Joomla 5 upgrades to Joomla 6 in place, and the published dates run to 2029. Nothing on this page depends on a deadline.

Why this matters

Functional value, value-stream value — and why it can't be ignored.

Functional value

Re-platforms a Joomla site to a static Astro front end on Cloudflare — either headless, with Joomla kept as the editing system and read through its core web services API, or fully extracted so the platform is retired. Content, structure, URLs and redirects are carried across.

Value-stream value

It creates a publishing path with no server in it: every page is built once and served from the edge, so the page arrives before a server-rendered one has finished querying the database. It enhances what the business already owns — the content model, the URLs and the search positions come across intact. And it protects the site by removing the surface that has to be watched: no PHP process in the request path, no per-request database, and no third-party extension facing the internet.

Why you can't ignore it

There is no date on this one, and that is exactly why it goes unexamined. Joomla 5 upgrades to Joomla 6 in place, so nothing arrives to force the decision, and the site keeps serving. What happens instead is slower and harder to see on a budget line. Every extension on the site is maintained by someone else, and they drop out one at a time — a form builder, a gallery, a members area — each one leaving a choice between running code nobody is fixing and paying to replace it. Joomla's own history shows where that ends: moving from Joomla 3 to Joomla 4 was a migration rather than a one-click upgrade, and extensions whose authors did not carry them forward had to be rebuilt or abandoned. Support for the project itself is volunteer-run, and when Joomla 3 reached the end of it in August 2023, continued security cover became a paid arrangement with a third party rather than part of the platform. Meanwhile the server stays in the request path, so PHP versions, database patching and hosting are a standing bill whether the site changes or not. None of this is urgent in any single month. The effect is cumulative: each upgrade costs more than the last, the list of things nobody will touch gets longer, and the day the site becomes cheaper to rebuild than to maintain arrives without anyone having decided it should.

One data layer · measured & owned

Every service creates data — captured, measured, owned.

Joomla → 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

Supabase Snowflake Keboola BigQuery

KPIs, dashboards & apps

Plotly 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 Joomla → 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.

DDefine

Agree the goal, value, budget & timescale up front.

MMeasure

Baseline the KPIs above — current state, not guesswork.

AAnalyse

Diagnose the real constraint and the solution needed.

IImprove

Build the chosen solution; prove the uplift.

CControl

Lock in the gains; monitor and sustain them.
