HaRP is designed for . It allows you to run resource-heavy applications—such as AI models requiring high-end GPUs—on separate physical hardware while maintaining a seamless user experience within the main Nextcloud interface. A single HaRP instance can even manage up to 99 different Docker Engines across your network. Why You Should Care

Once registered, click “Test deploy” to verify that everything is working correctly. The test should create a temporary ExApp container, verify that HaRP can reach it, and then clean up after itself. harp nextcloud

Do you have an existing (e.g., SAN, Ceph, S3)?

In a standard setup, if the server goes down, operations halt. HARP eliminates single points of failure (SPOFs) by utilizing stateless application nodes behind a load balancer (such as HAProxy or NGINX Plus). If one Nextcloud application server crashes, traffic is instantly rerouted to healthy nodes without user disruption. 2. Agile Scaling location /exapps/ proxy_pass http://127

When deployed, the HaRP container abstracts network mapping into three distinct, dedicated channels:

If you are a maintainer or power user, the message from the Nextcloud Developer Manual is clear: . It is scheduled for removal in Nextcloud 35. Switching to HaRP now ensures your ecosystem is future-proof, more secure with its built-in brute-force protection, and significantly faster. Why You Should Care Once registered, click “Test

Each hash includes previous hash, so d7e2 commits the entire history.

HaRP shifts the communication paradigm from resource-heavy polling to direct, dynamic routing. The underlying system functions across three specialized communication ports:

To understand the value of HaRP, it helps to understand how the Nextcloud AppAPI ecosystem manages External Apps (). ExApps allow developers to write integrations in any language (Python, Go, Node.js) and package them into containers that attach directly to the Nextcloud user interface. This prevents massive PHP monolithic bloat and facilitates highly intensive features—like local AI processing via the Nextcloud Assistant.

Nextcloud (Nextcloud GmbH, 2025) is a leading on-premises cloud storage platform used by enterprises, research institutions, and individuals seeking data sovereignty. Its core strengths include file versioning, sharing, WebDAV access, and extensible apps. Nevertheless, as deployments scale to multiple geographically distributed nodes (e.g., in a federated or edge-cloud setup), two limitations emerge:
