What it does
MergeFix is an autonomous AI agent for website owners. You give it a URL for a free audit, or install its GitHub App on a repository. It then crawls the site, runs checks for each topic and ranks the fixes by impact. The fixes arrive as a pull request with documented changes that you review and merge yourself. Its services cover SEO, GEO (getting cited by AI assistants), Core Web Vitals, accessibility, AI-written content, schema markup, image optimization, internal linking and security headers. Work happens in a fork that you create, so your production code is not touched until you choose to merge. A separate Migrate & Own service moves a project built with tools such as Bolt.new, Lovable, v0 or Replit into your own GitHub repository. It includes an audit and a production-ready pull request, so the project no longer depends on the platform that generated it. The company describes itself as EU-based and GDPR-compliant, and states that it does not sell data or train AI models on customer code.
