In their own words
LibreCrawl
LibreCrawl is a web-based SEO crawler for auditing and analyzing websites. It checks technical areas such as meta tags, schema markup, hreflang, social tags and PageSpeed metrics. Playwright rendering lets it crawl JavaScript sites built with React, Vue, Angular or Next.js, in headed or headless mode. The maker says memory profiling and virtual scrolling support stable crawls of more than one million URLs. Results can be exported as CSV, JSON or XML, with custom field selection and no stated export restrictions. LibreCrawl is MIT-licensed and can be self-hosted. Its REST API supports crawl control, settings and exports, and uses session-based authentication for every endpoint. Guest API users are limited to three crawls per 24 hours, tracked by IP address. The maker says the software does not track users, collect analytics or send crawl data back to itself, and encourages self-hosting for privacy. It is free, with no subscriptions or paid tiers. The maker directs bug reports and feature requests to GitHub Issues and discussions to GitHub Discussions.
Screaming Frog SEO Log File Analyser
Screaming Frog SEO Log File Analyser is a desktop application for examining access logs and understanding search engine and AI bot activity. It installs locally and keeps log event data in a local database. It accepts Apache, W3C Extended, and Amazon Elastic Load Balancing logs, and can verify supported bots to identify spoofed requests. Reports cover crawled URLs, crawl frequency, response errors, redirects, bytes downloaded, and response times. Users can match imported data containing a URLs column against log activity, including crawls, directives, or external link data. Log files can be added by drag and drop, with analysis exported to CSV or Excel. The software can process millions of events, though capacity depends on hard drive space. It runs on Linux, macOS, and Windows. The free plan allows 1,000 log event lines and one project. The paid licence costs $139 per year and includes unlimited events and projects, subject to storage capacity. Free technical support is listed for both versions.
