Astro Development and Rescue Services for AI-Built Sites

Why Astro Is Winning Content Sites in 2026

Astro ships zero JavaScript by default, making perfect Lighthouse scores — 100/100/100/100 — routine rather than exceptional. When Cloudflare acquired Astro in January 2026, it validated what content teams and product marketers already knew: Astro is now the default choice for sites where performance and SEO are non-negotiable.

For content-heavy sites, Astro almost always outperforms Next.js on load time, Lighthouse scores, and Core Web Vitals — but it gets complicated quickly when an AI tool generated a half-working codebase. Islands architecture, content collections, and Cloudflare Pages deployment have their own failure modes that general-purpose developers don't see often enough to fix reliably. We do.

Common Astro Problems We Fix

These are the failure patterns we see most often in AI-generated and manually built Astro projects.

Hydration mismatches

Client-side islands disagree with server-rendered HTML, causing flickering, console errors, and inconsistent UI state that's hard to reproduce locally.

Build pipeline broken

`astro build` works locally but fails on Vercel, Netlify, or Cloudflare Pages — usually due to environment variables, adapter misconfiguration, or Node version conflicts.

Stuck on a content collection refactor

Migrating between markdown files and a headless CMS like Sanity or Storyblok without breaking existing routes, slugs, and image paths.

Performance lost in a framework mix

React, Vue, or Svelte islands shipping 200 KB+ of JavaScript that wipes out the performance advantage that made Astro the right choice in the first place.

Image and SEO regressions

`astro:assets` generating wrong image sizes or srcsets, broken Open Graph tags, missing canonical URLs, or structured data that fails validation after a content migration.

Integrations that fight Astro

Stripe, Supabase, Sanity, Storyblok, and Decap CMS all have SSR quirks specific to Astro's request model. Getting them to work reliably in server output mode takes experience, not experimentation.

Migrating to Astro From Another Stack

Most Astro migration projects we take on are coming from WordPress, Next.js, or Webflow. The technical lift is predictable once you've done it a few times, but the details are where projects stall.

We handle the full process from start to finish, following four phases on every migration:

Content audit — catalogue every page, asset, and content type before a single file is moved.
URL preservation — map each existing URL to its new destination, and set up 301 redirects for anything that changes.
Incremental cutover — migrate and validate in batches so your existing site stays live and indexed throughout the process.
SEO continuity — verify canonical tags, structured data, Open Graph metadata, and Core Web Vitals before and after DNS cutover.

Typical timelines

Up to 50 pages: approximately 2 weeks
100–200 pages: approximately 3–4 weeks
500+ pages: approximately 6–10 weeks, depending on CMS complexity

How We Work

1

Free assessment in 1 business day

Tell us where your Astro project is stuck or describe the site you want to migrate. We'll review the codebase or scope and send you a written assessment — what's broken, what it will take to fix, and an honest timeline.

2

Fix and finish in 2–6 weeks

We work in focused sprints with daily updates. You have a direct line to the engineer working on your project — not a project manager relaying messages. Scope changes are discussed openly, not billed silently.

3

Ship, handover, optional retainer

We ship to your production environment, document what was done, and hand over clean code. If you want ongoing support, our retainer starts at $1,800/month and covers priority fixes and feature additions.

Recent Work

SaaS marketing site migrated from Webflow to Astro in 18 days

47-page SaaS marketing site on Webflow, with content managed in Sanity. The client needed better Lighthouse scores to compete on Core Web Vitals and wanted out of Webflow's hosting costs. We migrated to Astro 5, wired Sanity as the content source, and deployed to Cloudflare Pages.

Results

Lighthouse: 100/98/100/100
TTFCP: 0.6 s (down from 3.1 s on Webflow)
47 pages migrated with full URL preservation
Zero SEO ranking regressions in 90-day post-launch tracking

Platforms

Platforms using Astro

These AI app platforms output Astro code. We rescue and extend projects built on all of them.

Cursor

Cursor generates .astro components without plugin context, producing broken component scaffolds. We add the Astro plugin config and regenerate correctly.

Astro on Cursor

Claude Code

Claude Code Astro projects pair best with the Astro Docs MCP server for context-aware generation. We configure the MCP integration and build the site.

Frequently Asked Questions

Yes — this is one of the most common things we do. AI tools like Bolt.new, Cursor, and v0 generate valid-looking Astro code that breaks in specific ways: islands that don't hydrate correctly, content collections that work locally but fail in CI, adapters configured for the wrong output mode. We audit the codebase in the first day, identify the specific failure points, and fix them systematically. You keep the code the AI generated — we just make it actually work.

Migration pricing depends on page count and CMS complexity. As a guide: 20–50 pages typically falls in the $4,500–$9,500 range as a fixed-price engagement. 100–200 pages is typically $9,500–$22,000. For projects outside these ranges, or where the source CMS adds significant complexity, we work on a time-and-materials basis at $70/hour with a 5-hour minimum. All projects start with a free written assessment so you know the scope before committing.

Not if the migration is done correctly. We map every existing URL before touching anything, set up 301 redirects for any URL changes, preserve canonical tags, structured data, and Open Graph metadata, and run a post-launch crawl to catch anything missed. We've completed 30+ Astro migrations without a meaningful ranking drop. SEO continuity is a first-class deliverable, not an afterthought.

All of them. Astro's output adapters behave differently depending on the deployment target, and we've shipped to all the major platforms. Cloudflare Pages is our default recommendation for new Astro projects — the edge network is a natural fit for Astro's performance profile — but if you have existing infrastructure on Vercel or Netlify, we work with that too. Self-hosted deployments via Docker or a VPS are also possible.

Hybrid islands are common and usually fine — the problem is when they're over-used. If you have React or Vue islands shipping more JavaScript than the rest of the site, we audit which components genuinely need client-side interactivity and convert the rest to static Astro components. This typically cuts JavaScript payload by 60–80% without changing anything visible to the user. If your islands are scoped correctly already, we leave them alone.
