The web changes with incredible speed. Hence all the hype around the real-time web, i.e. new content. A startup called Perpetually is looking at the opposite side of the changing web — websites where old content disappears, or which disappear themselves.
It works like a customizable version of the Internet Archive’s Wayback Machine, which stores old versions of many pages on the web. With Perpetually, you tell the site which websites and web pages you want it to store. Later on, you can search for for specific terms in those archives, or see a visual summary of how those pages looked over time.
Perpetually can focus even more closely than web pages — it says it’s already helping the Wall Street Journal highlight specific sections of its site, then see how that area looked at different points in time.
The company launched at the TechCrunch50 conference in the San Francisco today. Pricing depends on how much data you want to store, starting at $99 per year. The expert panel seemed to have reservations about that business model, and encouraged Perpetually to figure out ways to make some parts of its service free, so people can try it out before they need to pay.
