SEOMicroservicesAILive

Rank Orbit

An advanced SEO Audit and Analysis platform leveraging a microservices architecture to crawl websites, analyze performance metrics (Lighthouse), and generate AI-powered SEO insights.

Tackles the SEO audit problem by combining performance signals (Core Web Vitals, Lighthouse) with AI-driven content analysis. Plug in any URL and get a structured audit in minutes instead of hours of manual review.

Built as a microservices monorepo: a Next.js dashboard for users, a NestJS API gateway for orchestration, and FastAPI workers handling crawling, Puppeteer-based measurement, and analysis. Google Gemini and LangChain power the natural-language summaries on top of the raw signals.
