+# 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.)
