We’re excited to announce public beta support for HTTP/2 on both Heroku Common Runtime and Private Spaces. HTTP/2 support is one of the most requested and desired improvements for the Heroku platform. HTTP/2 is significantly faster than HTTP 1.1 by introducing features like multiplexing and header compression to reduce latency and therefore improve the end-user experience of Heroku apps.

Since 2023, we’ve been working on a large platform modernization of our Common Runtime router. This project will allow us to start delivering more modern networking for Heroku. With the majority of that work now complete, we’re excited to focus more on the future and new features.

Upgrading to HTTP/2, the next-generation HTTP protocol, significantly improves web app performance for our customers. Here's how:

Faster loading times: HTTP/2 uses header compression and multiplexing to deliver content quicker and more efficiently. This improvement translates to faster page loads, especially for content-heavy applications with many images or videos.
