SiteOne Crawler is a free website crawler and audit tool that examines SEO, performance, accessibility, security, best practices, and content. It produces an interactive HTML report or text and JSON output, and assigns a quality score from 0.0 to 10.0 across five areas: performance, SEO, security, accessibility, and best practices. It can save a static copy of a website for offline browsing, turn a whole site into Markdown, and generate llms.txt. An optional Chromium mode renders JavaScript-driven pages before crawling. The native Rust binary runs on Windows, macOS, and Linux, with desktop and command-line variants; it has no runtime dependencies. API access and self-hosting are also listed. A CI/CD quality gate offers configurable thresholds, JUnit XML, GitHub annotations, and exit code 10 when checks fail. Reports can be shared through a free service using secure URLs with optional expiration and password protection. The default crawl uses three workers and no more than 10 requests per second combined. Plans are listed at free.
