Do you ever need to check if a website changes? I use an automated site checker for this such as What’s this useful for?:

  • If you’re watching a product’s availability on a site, for example to buy a hard-to-find item such as a popular game console.
  • If you need to see if data or text changes on sites for your job, for whatever information is contained on those pages; this could be for data analysis or competitive research.
  • If you have your own website and want to see if it goes down for any reason.

There are probably many more reasons to check websites. Visualping and other sites make money by having you pay if you need checks more frequently than every day. There used to be many PC-installed software tools for this purpose, but this has largely moved to the cloud, which I think makes sense for simplicity and ease of use.
