Checks the provided website using Playwright. This is a low level runner, most likely you want to use the high level master actor -  https://apify.com/lukaskrivka/website-checker

The web checker actor loads URLs to check and checks for common captchas, status codes returned from crawling, as well as calculates the price a user may pay. TODO: Needs to be more descriptive!!

A CSS selector saying which links on the page (<code>&lt;a&gt;</code> elements with <code>href</code> 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 <a href='https://apify.com/apify/web-scraper#link-selector' target='_blank' rel='noopener'>Link selector</a> in README.

Specific options that are relevant for crawlers

Link Selector

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.

Maximum number of concurrent domains checked

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.

Maximum concurrent pages checked per domain

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 <code>0</code>, there is no limit.

Max number of pages checked per domain

Which type of browser should the checker use

Options passed to playwright when checking

Chrome

Firefox

Headfull browser (XVFB)

Only works for Playwright type! Be careful that Chrome is not guaranteed to work with Playwright.

Use Chrome instead of Chromium

Only works for playwright type. Will wait on each page. You can provide number in ms or a selector.

Wait for

Safari (Webkit)

Specifies proxy servers that will be used by the scraper in order to hide its origin. For details, see <a href='https://apify.com/apify/web-scraper#proxy-configuration' target='_blank' rel='noopener'>Proxy configuration</a> in README.

Proxy Configuration

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 <code>[]</code> brackets, e.g. <code>http://www.example.com/[.*]</code>. 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 <a href='https://apify.com/apify/web-scraper#pseudo-urls' target='_blank' rel='noopener'>Pseudo-URLs</a> in README.

Pseudo-URLs

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

Repeat checks on provided URLs

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

Retire browser instance after request count

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

Enabled

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 <a href='https://apify.com/apify/web-scraper#start-urls' target='_blank' rel='noopener'>Start URLs</a> in README.
