Links to these domains are skipped during crawling.
In the free plan, crawling runs in your browser, so you need to keep the browser tab open. If you close the page, the crawl stops.
In the paid Standard plan, crawling continues on the server even after you close your browser. Log back in and click the "Reconnect" button to see the latest results from where it left off.
Basic Authentication is a password protection method where your browser shows a dialog asking for a username and password when you visit the page.
With the paid plan, you can enter Basic Auth credentials in the "Advanced Settings" to check password-protected pages.
There is no limit on the number of pages, but there is a time limit per run:
- Free plan: up to 2 hours per run
- Paid plan: up to 24 hours per run

No. This tool collects links via HTTP requests and does not execute JavaScript.
For sites rendered with React, Vue.js, Next.js, or similar frameworks, some links may not be detected correctly.
The tool does not read or follow robots.txt. It sends requests to all discovered links.
If you want to skip specific URLs, use the "Exclude URL Patterns" feature available in the paid plan.
There is no page limit, but there is a time limit per run (free plan: 2 hours / paid plan: 24 hours).
Sites with thousands or tens of thousands of pages are supported, but we recommend setting an appropriate sleep interval to avoid putting excessive load on the target server.
Not exactly. Scheduled checks are evaluated every minute, and a check is triggered when the configured interval (daily, weekly, or monthly) has elapsed.
If the previous check is still running, the next one will wait until the following cycle.
Large services such as Amazon, Google, and YouTube do not accept bulk requests and may block IP addresses or return unreliable results.
For links to these services, we recommend manually verifying them in your browser.
