Rebuilding pre-rendering on a solid foundation

As mentioned in the introduction, our goal is to bring instant experiences to the whole web through prefetching and pre-rendering techniques that are privacy and developer friendly. This proof of concept experiment and the follow-up discussions with the community represent small, but nevertheless important, steps toward that goal. Indeed, any pre-rendering feature is inherently built on top of a prefetching capability, which must abide by the same privacy principles. There are a few more challenges that we’ll need to solve to bring back an improved, privacy and developer friendly, pre-rendering feature. To be clear, we see this successful proof of concept experiment as a positive signal for iterating on a viable web platform solution, so that more websites can both benefit from, and take advantage of the approach outlined in this blog post. We are hopeful that what we’ve learned from past efforts, as well as new learnings we’ve gained thanks to this proof-of-concept experiment, will help foster a fruitful collaborative effort with the rest of the community.
