SEOnaut

An open source SEO audit tool. It scans a domain and produces a report listing identified issues, grouped by severity as critical, high or low. Problems it detects include broken links that lead to missing pages, redirect issues such as temporary, permanent or looping ones, and missing or duplicate meta tags. It is built in Go, runs with Docker Compose and uses a crawler, and a quick start guide walks through setup, with sections on the technology, contributing and the license. MIT licensed and free to use, with topics that include technical SEO and crawling. Issues are sorted by severity and by their potential impact on SEO, so the most damaging problems can be fixed first. The tool is aimed at people who want an audit they can run themselves rather than a hosted service.
