Extract <title> from document and use as watch title

Send a notification when the filter can no longer be found on the page

Sends a notification when the filter can no longer be seen on the page, good for knowing when the page changed and your filter will not work anymore.

Fetch Method

Basic fast Plaintext/HTTP Client
WebDriver Chrome/Javascript via 'http://browser-selenium-chrome:4444/wd/hub'
System settings default

Use the Basic method (default) where your watched site doesn'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'.

Tip: Connect using Bright Data and Oxylabs Proxies, find out more here.

Error - This watch needs Chrome (with playwright/sockpuppetbrowser), but Chrome based fetching is not enabled. Alternatively try our very affordable subscription based service which has all this setup for you.

You may need to Enable playwright environment variable and uncomment the sockpuppetbrowser in the docker-compose.yml file.

Selenium/Webdriver cant be used here because it wont fetch screenshots reliably.

Notifications Muted / Off

Attach screenshot to notification (where possible)

Use with caution! This will easily fill up your email storage quota or flood other storages.

Use system defaults

Notification URL List

Tip: Use AppRise Notification URLs for notification to just about any service! Please read the notification services wiki here for important configuration notes.

`{{watch_url}}`	The URL being watched.
`{{watch_uuid}}`	The UUID of the watch.
`{{watch_title}}`	The title of the watch.
`{{watch_tag}}`	The watch group / tag
`{{preview_url}}`	The URL of the preview page generated by changedetection.io.
`{{diff_url}}`	The URL of the diff output for the watch.
`{{diff}}`	The diff output - only changes, additions, and removals
`{{diff_added}}`	The diff output - only changes and additions

For JSON payloads, use |tojson without quotes for automatic escaping, for example - { "name": {{ watch_title|tojson }} }

URL encoding, use |urlencode, for example - gets://hook-website.com/test.php?title={{ watch_title|urlencode }}

Notification format

Format for all notifications

Re-stock detection

In Stock only (Out Of Stock -> In Stock only)
Any availability changes
Off, don't follow availability/restock

Follow price changes

Changes in price should trigger a notification

Below price to trigger notification

Minimum amount, Trigger a change/notification when the price drops below this value.

Above price to trigger notification

Maximum amount, Trigger a change/notification when the price rises above this value.

Threshold in % for price changes since the original price

Price must change more than this % to trigger a change since the first check.
For example, If the product is $1,000 USD originally, 2% would mean it has to change more than $20 since the first check.
