A Practical Guide to Nextcloud App Development

Seminar 2

09:2035 mins14/11/2026

Nextcloud’s extensibility is core to its value as a sovereign, self-hosted platform; but the path from “I have an idea” to “I have a working app” isn’t always obvious.

This talk is a code-first walkthrough of Nextcloud app development as it stands today: app architecture, the bootstrapping and dependency injection model, and a live demo built from the official app-tutorial example. We’ll also cover ExApps, Nextcloud’s newer model for running app logic outside the core PHP process.

Expect concrete gotchas, debugging strategies, and a working mental model, plus a starting point you can clone and extend yourself.
