Any news on this?

I expect that website owners will only start to use early hints once a major browser supports it, but server-side support has been added in several servers/frameworks, for example:

• Apache HTTPD: https://httpd.apache.org/docs/2.4/howto/http2.html#earlyhints
• Puma & Rails (Ruby): https://eileencodes.com/posts/http2-early-hints/

nodejs also supports it

The upcoming release of lighttpd 1.4.56 supports 103 Early Hints

Some movement here on the chrome side, intent to prototype:

Dragana, not quite sure if the proposed use of 103 reponse for a chrome trial is a great idea. Any thoughts?

This is on my radar already. The document shows interesting possible performance improvement from the telemetry they have collected (it sounds also a bit high). There is not a good spec for this feature, e.g. integration with fetch spec is missing. In one of the docs they proposed 2 possible implementation, but I would prefer to have some spec or at lease a draft that we can discuss. Anne had similar comment.

I was thinking about adding telemetry to estimate possible performance improvement in Firefox (if you are interested to help :) ).

Is this picking up steam now here due to Cloudflare enabling beta Early Hints on accounts?

This is live in Cloudflare and out of beta, I just toggled it on for my website.

FYI - Chrome already had it, and Safari 17 also mentioned this.

Early Hints is rolled out. This bug still serves as a meta bug for backlog items from now on.
