SEOnaut

SEOnaut is an open-source SEO auditing tool designed to analyze websites for issues that may impact search engine rankings. It performs a comprehensive site scan and generates a report detailing any identified issues, organized by severity and potential impact on SEO.
SEOnaut categorizes issues into three levels of severity: critical, high, and low. The tool can detect various SEO-related problems, such as broken links (to avoid 404 errors), redirect issues (temporary, permanent, or loops), missing or duplicate meta tags, incorrectly ordered headings, and more.
A hosted version of SEOnaut is available at seonaut.org.

Technology
SEOnaut is a web-based application built with the Go programming language and a MySQL database for data storage. The frontend is designed for simplicity, using custom CSS and minimal vanilla JavaScript. Apache ECharts is used to provide an interactive dashboard experience.
While it is possible to configure a custom database and compile SEOnaut manually, using the provided Docker files is recommended. These files simplify the setup process and eliminate the need for manual configuration, allowing for quicker and easier deployment.
