About opensourcetools.online
opensourcetools.online is a free collection of technical SEO and web diagnostics tools. We built it for developers, marketers, and agencies who need fast, accurate checks without signing up for another dashboard.
The site focuses on indexation, on-page signals, links and redirects, performance, and domain or server data. Each tool is designed to show clear results and explain limits where third-party data or platform restrictions apply.
What we believe
SEO tooling should be transparent: you should understand what was measured, what was inferred, and what still requires your own judgment or access (for example, Google Search Console).
