Sken.io

Sken.io watches web pages for you and tells you when they change.

Describe a page and what matters on it in plain language, and Sken.io starts monitoring it: the price on a product listing, a competitor's pricing table, a careers page, a booking calendar, a supplier's terms. You pick how often it looks, from once a minute to once a day.

Every check is a real browser loading the real page, so Sken.io keeps a screenshot of the page before and after each change, with the changed area highlighted. That means you can ask what changed and get an actual answer about the page, instead of a link telling you to go and look yourself.

You can also review recent changes across everything you monitor, pause or retarget a monitor, group monitors by project, and send alerts on to e-mail, Slack, Discord, Google Chat, webhooks or Zapier so your team hears about a change even when you are not in a chat.

Requires a Sken.io account. Monitoring uses the check allowance on that account, and the connector reports how much of it is left when you ask.
