Important Note
Anchor checks links directly from the browser using standard HTTP requests.
Some websites may return incomplete or misleading results because of:
✗ Login or Authentication Requirements
✗ Bot Protection
✗ Rate Limiting
✗ Cross-Origin Restrictions
✗ Firewall Rules
✗ Temporary Server Errors
✗ Websites That Reject Automated Requests
✗ Restricted Browser Pages
A timeout or network error does not always prove that a URL is permanently broken. Users should manually verify important results before removing or replacing links.
Anchor does not include:
✗ Cloud Report Storage
✗ Scheduled Website Crawling
✗ Multi-Page Website Crawling
✗ User Accounts
✗ Remote Link-Checking Infrastructure
✗ Browser Marketplace Publication
