What it is
LibreCrawl is a free, open-source web crawler for technical SEO audits and website analysis. It checks meta tags, schema markup, hreflang, social tags, PageSpeed metrics, and other technical issues. Playwright rendering lets it crawl JavaScript sites, including React, Vue, Angular, and Next.js applications, in headed or headless mode. The maker says memory profiling and virtual scrolling support stable crawling of more than one million URLs. Results can be exported as CSV, JSON, or XML with custom field selection. Its REST API provides crawl-control, settings, and export endpoints, and requires session-based authentication for every endpoint. Guest API users are limited to three crawls per 24 hours, tracked by IP address. LibreCrawl is MIT-licensed and can be self-hosted; supported platforms include web, Linux, macOS, and Windows. The maker says it does not track users, collect analytics, or send crawl data back to itself, and encourages self-hosting for privacy. It is free, with no paid tiers or subscription.

The verdict
LibreCrawl focuses on technical crawling, JavaScript rendering, and exportable audit data. Its API guest limit and lack of keyword, rank, backlink, and competitor tools are worth considering.
