Frequently Asked Questions
With concurrency set to 50, you can check approximately 500 URLs per minute. Actual speed depends on target server response times.
We use HEAD requests by default, which are lightweight and have minimal impact. For very large batches, consider using lower concurrency.
The free version checks public URLs only. Pro users can add custom headers including authentication tokens.
4xx (client errors like 404 Not Found) and 5xx (server errors like 500 Internal Server Error) are flagged as issues. 3xx redirects are shown separately.
