DiffHook is a web monitoring tool that automatically watches any website for you and sends you an alert the moment something changes. Whether it is a competitor updating their prices, a government page publishing new regulations, or a product coming back in stock or even an RSS feed, DiffHook catches it right away so you never miss what matters. You simply tell DiffHook what to watch and how often to check it. It runs quietly in the background, comparing each new version of the page to the previous one. When it spots a difference, it notifies you through the channels you already use: email, Slack, Discord, Telegram, or any other tool in your workflow. DiffHook is used by businesses, researchers, and teams of all sizes to stay on top of external changes without having to manually check websites themselves. It saves time, reduces the risk of missing critical updates, and turns the open web into a reliable source of real-time information for your team.
