Notify is a (very stupid) ruby script that will periodically visit a web page and notify you based on changing web content which you specify.

For example - you would like to know when a certain product page no longer displays the text "Not in stock". IE you want a Logitech camera and don't want to spend all your free time refreshing the product page.

{
  "url": "https://www.logitech.com/de-de/product/hd-pro-webcam-c920s",
  "criteria": {
    "js_selector": "#section-product-hero > div.container.product-hero-container-top.js-productContainerTop > div.product-details-ctn.js-productDetailsCtn > div > div.product-details-block.cart.buyAtPartner.black > div > p.product-hero-availability-message",
    "match": {
      "condition": "ne",
      "text": "Nicht auf Lager"
    }
  },
  "interval": 60
},
...
