What is Black SEO Analyzer?

Black SEO Analyzer is an SEO audit tool built in Rust that scans websites for technical and content-related issues. It works as both a command-line tool and desktop application, and can crawl traditional websites as well as single-page applications using headless Chrome. The tool runs over 300 checks covering technical SEO, page speed, Web Vitals, accessibility, security, links, and Schema.org validation. It integrates with AI models from Anthropic, OpenAI, DeepSeek, and Google to generate insights about your site's performance. Reports can be exported in multiple formats including HTML, JSON, XML, and CSV, making it useful for sharing results with clients or teams. Because it's a one-time purchase with source code access, it suits agencies, developers, and enterprises who want to own their tools rather than rely on subscriptions.
