Nextcloud is a self-hosted file sync and collaboration platform. "Harp Nextcloud" typically refers to deploying Nextcloud on a server managed with Harp (a simple static web server/build tool) or a hosting setup named Harp. Below is a concise, practical blog-style guide for installing Nextcloud on a typical Linux VPS using Apache, PHP, and MariaDB—adapt this to your Harp-based environment by serving PHP/backend appropriately or using Harp for static assets and a separate PHP-FPM/Apache backend.
SSH into your target server:
ssh root@your-server-ip
While Harp will handle most configurations, the server needs to be minimally prepared. Run the following to update the system and install basic tools:
apt update && apt upgrade -y
apt install -y curl git ufw
Firewall Configuration (UFW): Harp will need ports 22 (SSH), 80 (HTTP), and 443 (HTTPS) open.
ufw allow 22/tcp
ufw allow 80/tcp
ufw allow 443/tcp
ufw enable
Now, exit the SSH session and return to your local machine. We will now deploy from local to remote. harp nextcloud install
SSH into your Nextcloud server:
cd /var/www/nextcloud/custom_apps
sudo git clone https://github.com/gabrielbruin/harp.git
Note: Your Nextcloud path might be /var/www/html/nextcloud or /apps/www/nextcloud. Adjust accordingly.
Once you experience the freedom of self-hosted music, you will never go back to a leased, ad-infested service. Harp makes sure of that.

Unlocking High-Performance Microservices: A Guide to Nextcloud HaRP
Nextcloud has evolved from a simple file-sharing tool into a comprehensive productivity suite. With the release of Nextcloud 32, a new architectural component called HaRP (High-performance AppAPI Reverse Proxy)
has become the recommended way to manage "ExApps"—external applications that run as microservices outside the main PHP stack.
This guide explores what HaRP is, why it’s essential for modern Nextcloud deployments, and how to install it. What is HaRP? Historically, Nextcloud used a Docker Socket Proxy (DSP) While Harp will handle most configurations, the server
to manage external apps. However, DSP had limitations, particularly with real-time features like WebSockets.
replaces the old system by acting as a fast reverse proxy that: Enables WebSockets : Allows real-time communication for apps like Nextcloud Talk without passing through the heavy PHP stack. Simplifies Networking
: ExApps no longer need to expose ports to the host; they connect outbound to HaRP using an internal FRP (Fast Reverse Proxy) client. Improves Performance
: Reduces resource overhead by routing traffic directly to the containerized microservices. Prerequisites Before you begin, ensure you have: Nextcloud 32 or higher installed. Docker and Docker Compose set up on your server. app enabled within your Nextcloud instance. Step 1: Deploy the HaRP Container
HaRP is distributed as a Docker image. You can deploy it using a simple docker run command or a Compose file. Essential Environment Variables: HP_SHARED_KEY : A secure password shared between Nextcloud and HaRP. NC_INSTANCE_URL : The URL of your Nextcloud instance (e.g.,
Require Two-Factor Authentication for any user accessing Harp. Go to Nextcloud Settings -> Security -> Two-Factor Authentication and enforce it.
