Use the Basic method (default) where your watched sites don't need Javascript to render.

The Chrome/Javascript method requires a network connection to a running WebDriver+Chrome server, set by the ENV var 'WEBDRIVER_URL'.

If you're having trouble waiting for the page to be fully rendered (text missing etc), try increasing the 'wait' time here.
This will wait n seconds before extracting the text.
{{ render_field(form.application.form.webdriver_delay) }}
{{ render_field(form.requests.form.default_ua) }} Applied to all requests.

Note: Simply changing the User-Agent often does not defeat anti-robot technologies, it's important to consider all of the ways that the browser is detected.
{{ render_checkbox_field(form.application.form.ignore_whitespace) }} Ignore whitespace, tabs and new-lines/line-feeds when considering if a change was detected.
Note: Changing this will change the status of your existing watches, possibly trigger alerts etc.
{{ render_checkbox_field(form.application.form.render_anchor_tag_content) }} Render anchor tag content, default disabled, when enabled renders links as (link text)[https://somesite.com]

  • Note: This is applied globally in addition to the per-watch rules.
  • Each line processed separately, any line matching will be ignored (removed before creating the checksum)
  • Regular Expression support, wrap the entire line in forward slash /regex/
  • Changing this will affect the comparison checksum which may trigger an alert
  • Use the preview/show current tab to see ignores

Your proxy provider may need to whitelist our IP of 204.15.192.195

Tip: "Residential" and "Mobile" proxy type can be more successfull than "Data Center" for blocked websites.

{{ render_field(form.requests.form.extra_proxies) }} "Name" will be used for selecting the proxy in the Watch Edit settings
SOCKS5 proxies with authentication are only supported with 'plain requests' fetcher, for other fetchers you should whitelist the IP access instead

Extra Browsers can be attached to further defeat CAPTCHA's on websites that are particularly hard to scrape.
Simply paste the connection address into the box, More instructions and examples here
