Public beta of HTTP/2 is now available for all runtimes

Change effective on 07 May 2024

HTTP/2 is now available for the Common Runtime and Private and Shield Private Spaces.

For the Common Runtime, we enable HTTP/2 by default on the new public beta router.

To enable HTTP/2 for Common Runtime applications, you must also opt into the Router 2.0 beta by running the following command:

heroku labs:enable http-routing-2-dot-0 -a <app name>

For Private and Shield Space apps, you can enable HTTP/2 for each individual app with a Heroku Labs flag:

heroku labs:enable spaces-http2 -a <app name>
