Show HN: LibreCrawl – Open-source SEO crawler with unlimited URLs (Free SF alt)

Screaming Frog costs $259/year per user, has a 500 URL free limit, and crashes on large sites due to memory issues. For agencies with 5+ team members, that's $1,300+ annually.

LibreCrawl is completely free, handles 1M+ URLs smoothly using virtual scrolling and memory profiling, and includes features even paid tools don't have (multi-session support, custom CSS injection, real-time memory dashboard).

It's MIT licensed and self-hostable for complete data control.

Would love feedback from the HN community!
