# Crawlfix AI: JavaScript SEO and AI Visibility Scanner

Crawlfix compares raw HTML to the rendered DOM, finds JavaScript SEO, AI visibility, and accessibility issues, and returns agent-ready fix prompts. Start free, no card required.

## What Crawlfix does

Each scan hits the URL twice. Once as a plain HTTP request with no JavaScript, the way a first-pass crawler sees it. Once in real headless Chromium, after hydration, the way your customer sees it. We diff the two and ship a report of everything that exists in the rendered DOM but is missing from the raw HTML.

Every finding comes with a framework-specific code patch and an acceptance checklist so you know when it is fixed.

## Who it is for

- Frontend developers shipping React, Next.js, Vue, Nuxt, SvelteKit, Remix, Astro, or Angular
- Indie founders losing ranking after deploys
- SEO consultants and small agencies auditing client sites
- Teams running AI coding agents (Claude Code, Cursor, Windsurf, ChatGPT) that need exact fix prompts

## How it works

1. Submit any public URL. No account required for the free preview.
2. Crawlfix fetches the raw HTML and renders the page in headless Chromium.
3. We run checks across indexability, metadata, schema, links, hydration, AI visibility, accessibility, cookies, consent, and security headers.
4. The DigitalOcean GenAI Platform generates a fix recipe and an agent-ready prompt for each issue.
5. Paste the prompt into your AI coding agent, ship the fix, then run a verification scan to confirm the gap closed.

## What gets checked

- Raw HTML vs rendered DOM diff
- Canonicals, titles, descriptions, structured data
- AI visibility across Perplexity, ChatGPT Search, Claude Web, Gemini, Copilot, DuckAssist
- llms.txt presence, FAQ schema, Article schema, citation surface
- Privacy policy, cookie consent, GDPR and CCPA signal coverage
- Security headers (CSP, HSTS, X-Frame-Options)
- Sensitive file probes (.env leaks, exposed .git, source maps)

## Free vs paid

Free scans show the risk score, screenshot, summary, and the top 3 issues. Paid plans unlock every issue, every fix recipe, exports, the REST API, MCP access, scheduled monitoring, compliance readiness, and policy generation. Plans run from Starter through Agency and Enterprise.

## Read-only by default

Crawlfix never touches your repository. We audit from the outside and hand you the fixes. Your developer or AI coding agent makes the code changes. Contact: Michael@faction.chat.
