HaRP is the engine that powers some of Nextcloud's most advanced features. Here are three primary use cases where HaRP shines:
HaRP directly addresses both of these issues. By bypassing the Nextcloud instance and handling WebSocket traffic natively, it opens the door to a whole new class of applications that can run inside Nextcloud without compromising on performance or user experience.

For any administrator running Nextcloud 32 or newer and using the AppAPI, the answer is a clear . The benefits are overwhelming: superior performance, built-in security, easier management, and, most importantly, the crucial ability to support real-time WebSocket connections.
HaRP allows clients and the Web UI to communicate directly with ExApps, bypassing the Nextcloud PHP stack. This significantly reduces server load and improves response times. HaRP is the engine that powers some of
Combining and Nextcloud creates a private, automated static site publishing system. It bypasses commercial hosting providers and complex CI/CD build scripts. By mapping Harp directly to your Nextcloud file system, you create a cloud-connected static CMS that respects your data sovereignty.
HaRP is more than just a performance upgrade; it's a foundational piece of Nextcloud's architecture for the years to come. By adopting HaRP, you are not just solving today's problems; you are future-proofing your Nextcloud deployment. Automatically handles routing so about
To make this work, you register a HaRP deploy daemon as a “manual install” type rather than a Docker install. The Nextcloud community has confirmed that this approach works: one user reported running the Context Chat backend on a remote GPU machine while the HaRP container ran on the main Nextcloud server, and the ExApp communicated successfully across the two hosts.
