Frequently asked questions
Everything you need to know about our crawler.
How fast is the crawler?
Crawl speed depends on your site size and plan. Small sites (< 100 pages) typically complete in 1-5 minutes. Larger sites take longer but our concurrent crawler with up to 10 simultaneous connections ensures fast, efficient scanning without overloading your server.
Does the crawler support JavaScript-rendered sites?
Yes! Our crawler includes headless browser rendering to fully support modern frameworks like React, Vue, Next.js, and single-page applications. We render JavaScript just like a real browser to ensure complete coverage.
Will crawling impact my server performance?
No. Our crawler is designed to be respectful and implements rate limiting, politeness delays, and concurrent connection limits. We honor robots.txt and can adjust crawl speed if needed. Most sites experience no noticeable impact.
What happens if I hit my crawl limits?
If you reach your plan's URL limit, the crawler will stop at that point and analyze what it found. You can upgrade your plan for higher limits or manually configure crawl depth to focus on specific sections of your site.
Can I crawl password-protected pages?
Currently, our crawler only analyzes publicly accessible pages. Support for authenticated crawling (login-protected areas) is on our roadmap. You can crawl staging sites that are public but use DNS verification for security.
How does automated scheduling work?
On Solo, Pro, and Agency plans, you can schedule crawls to run automatically at your chosen frequency (weekly, daily, or hourly). You'll receive email alerts when issues are detected, so you can fix problems proactively without manual monitoring.
What makes your crawler different from free tools?
Unlike basic tools, we provide comprehensive analysis (SSL, redirects, SEO, sitemaps), AI-powered insights, automated scheduling, historical tracking, team collaboration, and agency features like white-label reports. Plus, our crawler respects your server and provides real-time progress updates.
Can I export crawl data?
Yes! All plans can export link data as CSV. Pro and Agency plans can export full page content as markdown files (perfect for content migration). You can also generate PDF reports and use our API (Agency plan) for custom integrations.
