Siteone Crawler

Website crawling, auditing, offline cloning, and markdown export using SiteOne Crawler (Rust). Trigger when the user asks to: crawl a website, audit/analyze a site for SEO/security/performance/accessibility, generate an HTML audit report, clone a website for offline browsing, export a website to markdown, generate a sitemap, stress/load test a site, or run a CI/CD quality gate check. Binary path: ~/.siteone-crawler/siteone-crawler

Cross-platform website crawler/analyzer written in Rust.

Setup (run once)

Before first use, ensure the binary exists. If not found, install it automatically:

1. Check if binary exists at the paths below (in order of priority):
   • $HOME/.siteone-crawler/siteone-crawler
   • Any siteone-crawler found in $PATH (via which siteone-crawler)
2. If neither exists, download the latest release from GitHub:

   bash

   INSTALL_DIR="$HOME/.siteone-crawler"
   mkdir -p "$INSTALL_DIR"
   # Detect OS/arch
   OS=$(uname -s | tr '[:upper:]' '[:lower:]')
   ARCH=$(uname -m)
   case "$ARCH" in x86_64) ARCH="x64" ;; aarch64|arm64) ARCH="arm64" ;; esac
   # Get latest release URL from GitHub API
   RELEASE_URL=$(curl -sL https://api.github.com/repos/janreges/siteone-crawler/releases/latest \
     | grep -oP "browser_download_url.*?${OS}-${ARCH}\.zip" | head -1 | sed 's/browser_download_url": "//')
   curl -sL "$RELEASE_URL" -o /tmp/siteone-crawler.zip \
     && unzip -o /tmp/siteone-crawler.zip -d /tmp/siteone-crawler \
     && mv /tmp/siteone-crawler/siteone-crawler "$INSTALL_DIR/" \
     && chmod +x "$INSTALL_DIR/siteone-crawler" \
     && rm -rf /tmp/siteone-crawler /tmp/siteone-crawler.zip
   

3. After installation, set CRAWLER to the resolved path and verify with $CRAWLER --version.

Binary

bash

CRAWLER="$HOME/.siteone-crawler/siteone-crawler"

If the above path doesn't exist, fall back to $(which siteone-crawler) after running Setup.

Always use the resolved path. The binary outputs colored text to terminal; use --no-color for script/pipeline usage and --output json for programmatic consumption.

Common Workflows

1. Quick Audit (HTML report)

bash

$CRAWLER --url="https://example.com" --output-html-report="/path/to/report.html"

Generates a self-contained interactive HTML audit report with quality scores (0.0-10.0) across Performance, SEO, Security, Accessibility, Best Practices.

2. Full Audit + JSON + Upload

bash

$CRAWLER --url="https://example.com" \
  --output-html-report="/path/to/report.html" \
  --output-json-file="/path/to/result.json" \
  --upload --upload-retention="7d"

3. Offline Clone

bash

$CRAWLER --url="https://example.com" --offline-export-dir="/path/to/offline-site" --disable-javascript

Use --disable-javascript for SPA/React sites to get a browsable static version. Use --allowed-domain-for-external-files="*" to include CDN assets.

4. Markdown Export

Multi-file (browsable):

bash

$CRAWLER --url="https://example.com" --markdown-export-dir="/path/to/md-export"

Single-file (ideal for AI tools):

bash

$CRAWLER --url="https://example.com" --markdown-export-dir="/tmp/md" --markdown-export-single-file="/path/to/site.md" \
  --markdown-disable-images --markdown-disable-files

5. Sitemap Generation

bash

$CRAWLER --url="https://example.com" --sitemap-xml-file="/path/to/sitemap" --sitemap-txt-file="/path/to/sitemap"

6. CI/CD Quality Gate

bash

$CRAWLER --url="https://example.com" --ci --ci-min-score="7.0" --ci-max-404="0" --ci-max-5xx="0"

Exit code 10 if thresholds not met. See references/cli-params.md for all --ci-* options.

7. Stress/Load Test

bash

$CRAWLER --url="https://example.com" --workers="20" --max-reqs-per-sec="100" --max-depth="1"

Warning: high worker counts can cause DoS. Use with caution.

8. Single Page Crawl

bash

$CRAWLER --url="https://example.com/about" --single-page --output-json-file="/path/to/result.json"

9. HTML-to-Markdown (local file)

bash

$CRAWLER --html-to-markdown="/path/to/page.html" --html-to-markdown-output="/path/to/page.md"

10. Browse Exported Content

bash

$CRAWLER --serve-markdown="/path/to/md-export" --serve-port="8321"
$CRAWLER --serve-offline="/path/to/offline-site" --serve-port="8321"

Script Helpers

scripts/audit.sh — Quick audit wrapper

Runs a full crawl with HTML report and optional JSON output. See script for usage.

scripts/export-markdown.sh — Markdown export wrapper

Exports a website to markdown (single or multi-file). See script for usage.

Tips

• For modern JS frameworks (Next.js, React, Vue), add --disable-javascript when doing offline exports
• Use --output json for programmatic processing; JSON goes to STDOUT, progress to STDERR
• Use --extra-columns="Title,Keywords,Description" to add SEO columns
• Use --timezone="Asia/Shanghai" for local timestamps
• For large sites, increase --memory-limit, --max-visited-urls, and --max-queue-length
• Use --resolve to test local/dev servers (like curl --resolve)
• HTML reports are self-contained — open in any browser, no server needed
