Website Checker

A static list of URLs to check for captchas. To be able to add new URLs on the fly, enable the Use request queue option.

For details, see Start URLs in README.

Specifies proxy servers that will be used by the scraper in order to hide its origin.

For details, see Proxy configuration in README.

Crawl with Cheerio

Crawl with Puppeteer

Crawl with Playwright

Will save HTML for Cheerio and HTML + screenshot for Puppeteer/Playwright

Will enqueue any URLs on the domain

A CSS selector saying which links on the page (<a> elements with href attribute) shall be followed and added to the request queue. This setting only applies if Use request queue is enabled. To filter the links added to the queue, use the Pseudo-URLs setting.

If Link selector is empty, the page links are ignored.

For details, see Link selector in README.

Specifies what kind of URLs found by Link selector should be added to the request queue. A pseudo-URL is a URL with regular expressions enclosed in [] brackets, e.g. http://www.example.com/[.*]. This setting only applies if the Use request queue option is enabled.

If Pseudo-URLs are omitted, the actor enqueues all links matched by the Link selector.

For details, see Pseudo-URLs in README.

Will access each URL multiple times. Useful to test the same URL or bypass blocking of the first page.

The maximum number of pages that the checker will load. The checker will stop when this limit is reached. It's always a good idea to set this limit in order to prevent excess platform usage for misconfigured scrapers. Note that the actual number of pages loaded might be slightly higher than this value.

If set to 0, there is no limit.

Specifies the maximum number of pages that can be processed by the checker in parallel for one domain. The checker automatically increases and decreases concurrency based on available system resources. This option enables you to set an upper limit, for example to reduce the load on a target website.

Specifies the maximum number of domains that should be checked at a time. This setting is relevant when passing in more than one URL to check.

How often will the browser itself rotate. Pick a higher number for smaller consumption, pick a lower number to rotate (test) more proxies.

Specifies the maximum time in seconds the request will wait for the page to load. If the page is not loaded within this time, the browser will throw an error and the page will be marked as failed.
