Live demo on my website @ https://sysadmincasts.com/ Temporary added it in-line for testing. I was already in the sub 100ms level but this just puts it over the top! Also updated…

Just set this up on guidevinetech.com, injected via tag manager. Works a treat, pages are definitely _fast_

This is very nice idea, but isn't the problem initial liad time most of the time? How could we solve that? Does this also work for all the outgoing links as well? I don't want to…

"49 ms from hover to click" -- I guess I'm not exactly the target audience... However, I find it very good the posted snippets include SRI, which sadly to this day almost every…

If you like to hyper optimize your site like me, and since it doesn't do any good on mobile (Edit: apparently it works on mobile, ignore this), you can have it selectively grab…

Thanks. The only downside is that you can expect twice the number of requests to your pages (only the pages themselves, not their assets).

The downside is that your pages’s HTML are loaded twice as much, this makes for additional load on your server. Client-side analytics like GA aren’t affected.

Why use this script as an include from the instant.page domain? I think if I'm going to use this I'm just going to serve this script up myself from my own servers.

I have just added it to a Shopify store to try it and it does indeed speed things up! However I am a little concerned with adding a script from another website... it requires a…

I wouldn't want to expose my various site's users to third party code execution like this.

This is cool, and the license as shown at https://instant.page/license is the well-known MIT license, already known to be be an open source software license…

Probably doesn't work with an agent that doesn't support hover events. Such as on tablets and smartphones.

I guess nobody has mentioned this yet, but it presumably doesn't work on mobile? I wonder if you could do something similar simply by looking at the viewport and loading all the…

Each time you hover over a link it's doing a GET request bypassing the cache (cache-control: max-age), even if you hove the same multiple times. Also this will make all your…

It seems everybody is missing this but this could actually slow down your experience, and I'd actually guess it will in some scenarios (ie. not only a theoretical situation).…

Make it opt-in (vs opt-out)? As best I can tell, there is only the blacklist functionality (via a markup attribute). I can imagine many use cases where it would be far easier to…

Could this be made as a browser extension?

This should be implemented at the browser level, not in a webpage.

Perhaps this something that a browser should be doing, instead of websites themselves?

Can we see the Cloudflare Worker?

I'm curious how this is better than Google quicklink (https://github.com/GoogleChromeLabs/quicklink) which is something I have active on my site currently. Can someone with more…

Same preloading technique but quicklink preloads more agressively.

How does this work on devices with touch screen? (My apologies if this question has already been raised)

I guess nobody has mentioned this yet, but it presumably doesn't work on mobile? I wonder if you could do something similar simply by looking at the viewport and loading all the…

I looked (quickly) through most of the comments below and couldn't answer these questions: 1) What, if anything, is the downside here? 2) Is (Google) analytics effected by the…

The downside is that your pages’s HTML are loaded twice as much, this makes for additional load on your server. Client-side analytics like GA aren’t affected.

Is this a re-rebranding? I remember using something similar 4-5 years ago (instant.js/instantclick). But quite an interesting little thing, especially useful for older websites…

Kind of. It’s different than InstantClick in that it uses <link rel="prefetch"> and can thus be embedded in one minute, while InstantClick transforms a site into an SPA and…

Is this kind of like turbolinks which Basecamp uses?

What would be the best way to integrate this in an app that already uses Turbolinks?

This is a feature available on most web frameworks today (for example Link's prefetch on Next.js), but still could be very useful for smaller website and other static pages not…
