Inside your Nextcloud apps directory:

Historically, Nextcloud relied on the to manage external integrations. While functional, DSP is being deprecated—with removal scheduled for Nextcloud 35—due to its complexity and inability to support modern protocols like WebSockets. HaRP (Nextcloud AppAPI HaProxy Reverse Proxy) serves as a modern replacement, designed to simplify deployment while significantly boosting performance for real-time features. 2. Key Architectural Components

, HaRP is the successor to the older Docker Socket Proxy (DSP) and is now the recommended way to deploy External Apps (ExApps) What is HaRP?

"Files are duplicating." Fix: Ensure you have disabled Nextcloud's native "Object Store" cache. Harp uses its own versioning. Set 'harp.versioning' => 'server_authoritative' in config.php.

A single HaRP instance can manage multiple Docker engines, facilitating large-scale distributed environments. 4. Conclusion

tunnels to connect ExApp containers. This means apps don't need to expose ports to the host, simplifying networking and NAT traversal. Language Agnostic

is a dedicated proxy system built to streamline how external microservice applications integrate with Nextcloud Hub . Officially introduced as the recommended deployment daemon for Nextcloud 32+ environments , HaRP drastically cuts down networking friction, improves server responsiveness, and brings native support for real-time protocols like WebSockets.

: The local web communication gateway where Nextcloud talks directly to HaRP.

Create a shared network so HaRP can talk to your Nextcloud instance. docker network create nextcloud-network Use code with caution. Copied to clipboard 2. Run the HaRP Container Pull and run the latest HaRP container.

HaRP achieves its performance gains by merging two foundational networking utilities into a single Dockerized container: and Fast Reverse Proxy (FRP) .
