The record

Site audit: Yes
Purpose: SiteOne Crawler crawls websites and analyzes SEO, performance, accessibility, security, best practices, and content, then produces an interactive HTML report or text and JSON output.
Quality scoring: It assigns a 0.0–10.0 quality score across performance, SEO, security, accessibility, and best practices.
Offline copy: It can export a static copy of a website for offline browsing.
Markdown export: It can convert an entire website to Markdown and generate llms.txt.
JavaScript sites: Optional browser mode uses Chromium to render pages so JavaScript-driven sites can be crawled with their post-render DOM.
AI integrations: Its opt-in AI assistant supports OpenAI, Anthropic, Google Gemini, vLLM, Ollama, LM Studio, and OpenAI-compatible endpoints.
CI/CD: The built-in CI/CD quality gate supports configurable thresholds, JUnit XML, GitHub annotations, and exit code 10 on failure.
Supported systems: The single native binary runs on Windows, macOS, and Linux, with desktop and command-line variants.
Runtime dependencies: The Rust binary has zero runtime dependencies, with no Node, Python, or Docker required.
Report sharing: A free report-sharing service can provide a secure URL with optional expiration and password protection.
Default crawl rate: By default, it uses three workers and no more than 10 requests per second combined.
Audience: The maker identifies website owners, developers, QA engineers, administrators, DevOps practitioners, and consultants as intended users.
Support: The maker lists GitHub Issues for bugs and feature requests and GitHub Discussions for questions and discussion.
