You should have full control over your data. We help you achieve that: a safe home for all your data. Secure, under your control and developed in an open, transparent and trustworthy way. We are Nextcloud.
Nextcloud, the next generation Enterprise File Sync & Share was started by ownCloud inventor Frank Karlitschek to empower users to take back control over their data and communication. The company was founded as a spin-off from Struktur AG, a leading web conferencing and financial planning software company since 1995, servicing customers like Deutsche Bank, Vodafone, BNP Paribas and many others. Nextcloud gives organizations fine-grained control over data access, facilitates file synchronization and sharing across devices, enables collaboration within and across organizational boundaries and lets users communicate through secure WebRTC audio and video conferencing.
See our features page for more information about what Nextcloud can do for you.

Third-party components are handled as git submodules which have to be initialized first. So aside from the regular git checkout invoking
git submodule update --init or a similar command is needed, for details see Git documentation.
Several apps that are included by default in regular releases such as First run wizard or Activity are missing in
master and have to be installed manually by cloning them into the
Otherwise, git checkouts can be handled the same as release archives, by using the
stable* branches. Note they should never be used on production systems.
Working with front-end code 🏗
We are moving more and more toward using Vue.js in the front-end, starting with Settings. For building the code on changes, use these terminal commands in the root folder:
# install dependencies make dev-setup # build for development make build-js # build for development and watch edits make watch-js # build for production with minification make build-js-production
When making changes, also commit the compiled files!
We still use Handlebars templates in some places in Files and Settings. We will replace these step-by-step with Vue.js, but in the meantime, you need to compile them separately.
If you don’t have Handlebars installed yet, you can do it with this terminal command:
sudo npm install -g handlebars
Then inside the root folder of your local Nextcloud development installation, run this command in the terminal every time you changed a
.handlebars file to compile it:
Before checking in JS changes, make sure to also build for production:
Then add the compiled files for committing.
To save some time, to only rebuild for a specific app, use the following and replace the module with the app name:
MODULE=user_status make build-js-production
Please note that if you used
make build-js or
make watch-js before, you'll notice that a lot of files were marked as changed, so might need to clear the workspace first.
Working with back-end code 🏗
When changing back-end PHP code, in general, no additional steps are needed before checking in.
However, if new files were created, you will need to run the following command to update the autoloader files:
After that, please also include the autoloader file changes in your commits.
Tools we use 🛠
- 👀 BrowserStack for cross-browser testing
- 🌊 WAVE for accessibility testing
- 🚨 Lighthouse for testing performance, accessibility, and more
