FreeCrawl is a desktop website crawler for SEO audits, positioned as a free, cross-platform alternative to Screaming Frog. Everything runs locally: per the README, "no telemetry, no cloud, MIT-licensed." It crawls a site and surfaces the usual audit signals so SEO practitioners can inspect structure, links, and on-page issues without sending their crawl data to a third party. Built in TypeScript.
It suits SEO professionals and auditors who want a local, no-cost crawler they fully control. Note it is still pre-1.0, so expect rough edges and verify coverage against your audit checklist before relying on it.
