Production scanner at crawlhound.com, async crawling, PDF reports
Existing SEO scanners are either too expensive for small businesses or too basic to be useful. Tools like Ahrefs and Semrush cost hundreds per month and overwhelm users with data they don't need. I needed a tool that could crawl entire websites, analyze on-page SEO factors, check structured data, validate meta tags, and generate actionable reports — all in a fast, modern web interface that anyone could understand without SEO expertise.
I built CrawlHound as a FastAPI web application with async crawling powered by httpx and BeautifulSoup. The scanner checks 20+ SEO factors per page including title length, meta descriptions, heading structure, Schema.org markup, image alt tags, internal linking, and content word count. Results are displayed in a responsive Jinja2/Tailwind interface with letter grades (A-F) and downloadable PDF reports. The grading system makes it immediately clear which issues are critical versus informational, so business owners can prioritize fixes without hiring an SEO consultant. The app runs on a Vultr VPS with systemd service management and Cloudflare CDN, serving real users in production at crawlhound.com.
