# Change detection
|
|
Periodically monitors websites for changes and sends a notification when a change is detected.
|
|
|
|
- can use plain http request (faster option) or playwright (headless chrome) to render websites with javascript
|
|
- can filter a site with css selectors (to e.g. only get notifications when a price changes)
|
|
- many useful options like executing javascript on a site, before detecting changes (useful to eg. login)
|
|
- uses apprise for notifications, so hundreds of options (email, slack, telegram, sms, etc.)
