Ordinary monitoring pings an address and shows green. Uptimo walks your whole checkout flow in a real browser every five minutes: it logs in, adds to the cart, reaches payment and checks the text you expect to see. When a step fails you get a video, a screenshot of that step and the full HAR file, recorded only on failure. Steps are picked from a list, so no code is involved. Servers and data stay in the EU. Free plan available.
