Sample report. Your targets are set in the audit.
Built on Astro 5 · Sanity · Cloudflare
Two ways to start

Start fresh, or bring your site with you.

Same team, same Astro stack, same weekly previews. The only difference is where week one begins.

Starting fresh

4–8 wk

No site yet, or a rebrand that deserves a clean slate.

Design system built from your brand, in Figma and code
A CMS your team picks: Sanity, Storyblok or Markdown
Performance budget agreed in week one
Schema, sitemap and Open Graph wired from day one

Moving to Astro

2–6 wk

On WordPress, Webflow, Next.js or Gatsby, and keeping every ranking.

Every URL inventoried and redirected
Content moved one-to-one, nothing retyped
SEO baseline measured before and after
Zero-downtime cutover on launch day
The problem

Your content is fine. The platform under it isn’t.

Same homepage, weighed twice. Most of the old page is code your visitors download and never use.

Sample transfer sizes for one marketing homepage, mobile.

Every edit waits on a developer

A headline change sits in a ticket queue for a week.

Plugins you’re afraid to update

Each update risks breaking the forms, the checkout, or both.

Slow where it counts

Most visits come from phones, and phones feel every kilobyte.

Rankings that slip

Weak Core Web Vitals hand your position to faster competitors.

Hosting bills that creep

You pay a server to rebuild the same page for every visitor.

Content you can’t take with you

Proprietary builders keep your pages when you decide to leave.

Migrations

Four ways in. One way out.

Each platform has its own traps. These are the playbooks we run, and what your team keeps on the other side.

WordPress to Astro

3–6 wk
What changes

Themes and plugins become typed components. Posts move to Sanity or Markdown.

What you keep

URLs, SEO metadata, the media library

Webflow to Astro

2–4 wk
What changes

Interactions are rebuilt clean. CMS collections become content collections.

What you keep

The design, every slug, every CMS item

Next.js to Astro

2–5 wk
What changes

Client bundles go. React stays only in components that need it.

What you keep

Components, routes, API endpoints

Gatsby to Astro

1–3 wk
What changes

The GraphQL data layer is replaced by content collections.

What you keep

Markdown, images, page structure
