Harp Nextcloud [verified] -

As enterprise data grows, self-hosted collaboration platforms face severe performance bottlenecks. Nextcloud is an excellent open-source alternative to Microsoft 365 or Google Workspace. However, scaling it to thousands of concurrent users requires moving past traditional single-server setups.

Elara learned that the Reykjavik instance was run by a collective of teens in a geothermal-heated garage. They had no idea about the grand history of the Harp Protocol. To them, Nextcloud was just "the shed"—a place to store their field recordings of Icelandic rimur chants and electronic remixes.

HaRP requires Nextcloud (Nextcloud Hub 25 Autumn or newer). You will also need a working Docker installation on the same host where Nextcloud is running (unless you’re using a remote deployment, which we’ll discuss later). harp nextcloud

| Parameter | Explanation | | :--- | :--- | | HP_SHARED_KEY | A strong, secret password used for internal authentication. | | NC_INSTANCE_URL | The full URL of your Nextcloud instance (e.g., https://cloud.example.com ). | | -v /var/run/docker.sock | Mounts the Docker socket so HaRP can manage ExApp containers. | | -p 8780:8780 | Exposes the HTTP frontend for ExApps on port 8780. | | -p 8782:8782 | Exposes the FRP (Fast Reverse Proxy) frontend on port 8782 for internal ExApp communication. |

HaRP is typically deployed via Docker, allowing it to communicate within the nextcloud_network or with external containers. Elara learned that the Reykjavik instance was run

Nextcloud has evolved from a simple file-syncing tool into a powerful, self-hosted application platform. With the release of Nextcloud 32, the focus has shifted heavily toward (External Applications)—sophisticated, containerized apps that run alongside Nextcloud to provide advanced functionality, such as AI services, specialized editors, or real-time communication tools.

If you use a reverse proxy (like Nginx or Caddy) in front of AIO, ensure that the /exapps/ path is correctly handled. Conclusion HaRP requires Nextcloud (Nextcloud Hub 25 Autumn or newer)

Harp is a static site server and build tool that compiles HTML templates, Markdown, and assets into a static site. Nextcloud is a self-hosted file sync and collaboration platform. Integrating Harp with Nextcloud is useful when you want to host or serve a static site from Nextcloud storage (for previews, sharing, or simple hosting behind a Nextcloud-enabled webserver), or use Nextcloud as a source for site content/assets while building with Harp.
