# Open SEO Crawler

Open SEO Crawler is a free, open-source SEO crawler you run locally: a self-hosted website SEO crawler and site audit tool that crawls any website for technical SEO issues. Fast, concurrent, and CMS-aware, it’s a drop-in alternative to Screaming Frog, Sitebulb, and Ahrefs Site Audit, with no accounts, no API keys, no cloud and no per-URL limits.
