    The SEO Problem with SPAs

    JavaScript-heavy Single Page Applications create a fundamental challenge: search engine bots don't always execute scripts, meaning your carefully crafted content becomes invisible to the very systems that determine your site's discoverability.

    DataJelly snapshots solve this by prerendering each route in a real browser and serving clean, bot-friendly HTML instantly — with no code changes, no config, fully automated.

    How Snapshots Work

    Route Capture

    Edge crawlers discover routes from your app

    Automated discovery of all public routes and pages

    Headless Rendering

    Each route is loaded in a real headless browser

    Puppeteer/Playwright executes JavaScript fully

    Clean HTML Extraction

    Scripts are executed, and the final DOM is captured

    Complete rendered HTML with all dynamic content

    Snapshot Storage

    Saved in blob storage + cached at the edge

    Cloudflare KV/R2 for global distribution

    Edge Delivery

    Search bots are automatically served fast, prerendered HTML

    Sub-100ms response times globally

    What's Inside a Snapshot

    <title>Amazing Product Page</title>
    <meta name="description" content="...">

    Page Content

    Fully rendered dynamic content...

    ✓ Screenshot captured
    ✓ Timing: 1.2s load
    ✓ Console: No errors

    Structured Data Collected Per Route:

    Final rendered HTML + DOM
    Meta tags (title, description, OG tags)
    Screenshots of the rendered page
    Timing metrics (load time, execution time)
    Console logs & error traces for debugging
    Headers and crawl data
