Website Builder Migrate Skill

Migrate a site built on a website builder (Webflow, Framer, Squarespace, Wix, Carrd, etc.) to a self-hosted static site. Uses wget to mirror the published site, then cleans up assets, URLs, and platform-specific artifacts so it's ready to deploy anywhere.

Installation

Via skills.sh (recommended)

npx skills add stevysmith/website-builder-migrate-skill

Via Claude Code plugin commands

/plugin marketplace add stevysmith/website-builder-migrate-skill
/plugin install website-builder-migrate@website-builder-migrate-skill

After installation, the /website-builder-migrate skill is available in Claude Code.

Usage

/website-builder-migrate https://www.example.com/

Pass the URL of a live, publicly accessible builder-hosted site. The skill will:

1. Mirror the full site including CDN-hosted assets (images, CSS, JS)
2. Consolidate into a clean site/ directory structure
3. Rewrite all asset URLs to local paths
4. Fix common builder-export issues (SRI integrity blocks, missing webpack chunks, mangled inline styles, double-encoded URLs, broken forms)
5. Verify all asset references resolve correctly
6. Deploy to Render, Netlify, Vercel, or any static host

Supported Platforms

The Phase 1–7 workflow is platform-agnostic, with a per-platform notes table for CDN domains, chunk patterns, and common gotchas:

For unfamiliar platforms, the skill includes a diagnostic checklist (CDN domain / SRI tags / chunk map) to drive the workflow.

What It Handles

• Multiple CDN site IDs (site assets vs CMS content)
• Inline background-image:url() assets that wget misses
• Mangled URLs from wget --convert-links in inline styles
• Double-encoded CMS filenames (%2520, %252B, %2526)
• Subdirectory page structures (blog posts, career pages, etc.)
• SRI integrity attribute blocks — the most common cause of a blank-rendered migration; --convert-links modifies CSS bytes so the SHA-384 hash no longer matches
• Dynamically-loaded webpack chunks — webflow.achunk.* and equivalents that wget doesn't catch
• CSS-internal url(../font.ttf) paths that break when assets are reorganized
• Platform metadata attribute cleanup (data-wf-*, data-framer-*, generator meta tags)
• In-browser verification step (catches what static asset checks miss)

Output Structure

site/
  index.html
  about.html
  blog.html
  post/                # blog posts
  careers/             # career pages
  assets/
    css/               # stylesheets
    js/                # builder runtime + chunks
    images/            # all media (images, SVGs, videos)

Prerequisites

• wget must be installed (comes with macOS/Linux)
• The site must be published and publicly accessible
• Optional: agent-browser skill for visual verification

Deploy

Tip: deploy to Stacktree first to verify the migration on a private, unguessable URL before pointing DNS anywhere — anonymous uploads need no signup and last 24 hours.

Limitations

• JavaScript interactions — the builder's runtime continues to work but is monolithic (Webflow ~500KB; Framer per-route bundles)
• CMS content — captured as static HTML at time of mirroring; won't update dynamically
• Forms — builder forms won't work without their backend; use Formspree, Netlify Forms, Basin, etc.
• Site search — native search won't work; use Algolia, Pagefind, or similar
• Wix and other heavily-SPA builders — wget mirroring may produce incomplete output for client-rendered content
