Today we are proud to announce that [HHVM](https://hhvm.com/) is available as an application service on Platform.sh.

<img src="https://mintcdn.com/upsun-c9761871/GmjO2Q50fc4SCexK/images/posts/unknown/release-hhvm/hhvm-logo.webp?fit=max&auto=format&n=GmjO2Q50fc4SCexK&q=85&s=3372e957c2d9d754edaff6791911d9c8" alt="HHVM" width="300" height="150" data-path="images/posts/unknown/release-hhvm/hhvm-logo.webp" />

HHVM is a drop-in replacement for the PHP interpreter which was initially created by engineers at Facebook, but which has evolved into an open-source project with a large community of contributors. It boasts dramatic gains in performance and scalability over PHP and introduces many new features as a dialect of the PHP language called [Hack](https://hacklang.org/). These include scalar typehints and a static type-checker, asynchronous I/O primitives for cooperative multi-tasking, and numerous native data structures (such as shapes and collections) that allow for improvements in developer productivity.

In particular, the HHVM team recently concluded a sprint focused on improving performance for open-source PHP content management systems.

Platform.sh looks forward to being one of the first PaaS hosting solutions to support applications running on HHVM. Check out our [public documentation](https://docs.platform.sh/user%5Fguide/reference/toolstacks/php/hhvm.html) for information on how to use and configure the service.
