Harp Nextcloud __exclusive__ Official

HaRP is typically deployed via Docker, allowing it to communicate within the nextcloud_network or with external containers.

By bypassing the heavy PHP stack and routing traffic directly from the client to the ExApp, HaRP significantly reduces response times. Security & Simplified Networking:

| Feature | HaRP | Docker Socket Proxy | |---------|------|---------------------| | | Direct routing bypassing Nextcloud PHP stack | Requests pass through Nextcloud instance | | WebSocket Support | ✅ Full support | ❌ Not available | | Protocol Support | HTTP, HTTPS, WebSockets, FRP | Limited to HTTP | | Deployment Complexity | Simplified container-based setup | More complex configuration | | Recommendation Status | ✅ Recommended for Nextcloud 32+ | ⚠️ Deprecated path | | Language Flexibility | ExApps in any language | ExApps in any language |

First, a quick clarification: while you may have searched for "harp," the correct term is , which stands for Nextcloud AppAPI HaProxy Reverse Proxy . It represents a significant leap forward in how Nextcloud interacts with external applications. harp nextcloud

By using a shared key and dedicated certificates, HaRP provides a more robust security model for managing external microservices. How to Install and Configure HaRP

What (Markdown, EJS, Sass) do you plan to use?

Harp is an open-source, cloud-native storage solution that provides a scalable, secure, and highly available storage platform for modern applications. Developed by the Linux Foundation, Harp is designed to work seamlessly with cloud-native applications, providing a robust and flexible storage solution that can adapt to the needs of growing businesses. HaRP is typically deployed via Docker, allowing it

The Nextcloud ecosystem is clearly moving toward HaRP as the standard for external app management. With WebSocket support unlocking real-time capabilities, simplified deployment reducing operational overhead, and the legacy Docker Socket Proxy on the deprecation path, HaRP represents not just an incremental improvement but a fundamental shift in how Nextcloud extensions will be built and deployed.

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

If you are running Docker on a remote host, the recommended setup involves the HaRP container on the local host managing the remote host's socket. HaRP vs. Docker Socket Proxy HaRP (Fast Proxy) Docker Socket Proxy (Old Method) Recommendation Recommended for Nextcloud 32+ Legacy/Alternative Traffic Routing Direct to App (Faster) Through Nextcloud (Slower) Setup Complexity Simple/Automated Complex/Manual Security High (Built-in Auth) Dependent on Configuration WebSockets Conclusion It represents a significant leap forward in how

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

"Harp says 'No direct connection' but Nextcloud works." Fix: Your corporate firewall is blocking UDP. Configure your Harp client to use a relay (TOR or a public STUN server).

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.
