What OxideSEO is

OxideSEO is a free desktop application for crawling websites and checking technical SEO. It runs on Linux, macOS, and Windows, with no subscription, URL limit, or external service dependency. Its 21 built-in rules cover meta tags, content, links, images, performance, and security. Crawl settings let users adjust concurrency and depth and filter URLs by pattern. Cross-page checks find duplicate titles, orphan pages, and broken internal links. The crawler respects robots.txt, applies per-domain rate limits and crawl delays, and discovers XML sitemaps. A headless webview can render JavaScript-heavy pages for single-page applications. Results can be exported as CSV, NDJSON, HTML, PDF, or XLSX. Optional AI analysis connects to OpenAI, Anthropic, or local Ollama models using user-provided API keys. Sandboxed WASM and native plugins can add custom rules, export formats, and post-crawl processing. The project says crawling stays on the user's machine without telemetry, analytics, or data leaving the computer. It is dual licensed under MIT and Apache 2.0.
