Fusio is written in PHP and requires at least version 7.4 and a database.

  • PHP >= 7.4
  • Database (supports: MySQL, PostgreSQL, MSSQL, Oracle)


There are two ways of downloading Fusio:

  • Download the latest release from Github
  • Use composer and run the command composer create-project fusio/fusio

Place the script in the www directory of your web server. After successfully downloading Fusio, please continue with the setup process. The setup process will help configure Fusio to work properly on your server.


Manual Setup

  • Adjust the configuration file
    Open the file .env in the Fusio directory and change the key FUSIO_URL to the domain pointing to the public folder. Also insert the database credentials to the FUSIO_DB_* keys.

  • Execute the installation command
    The installation script inserts the Fusio database schema into the provided database. It can be executed with the following command php bin/fusio install.

  • Create administrator user
    After the installation is complete you have to create a new administrator account. Therefor you can use the following command php bin/fusio adduser. Choose as account type "Administrator".

Installation Script

To use the install script instead of the manual setup above, point your browser to public/install.php. The script will help setup Fusio and configure it to work on your server.

Once you are done, for security reasons, remove the public/install.php script.


If the installation is complete you are able to login at the backend at /apps/fusio. In case the fusio folder does not exist you can also manually install the backend app through php bin/fusio marketplace:install fusio.

Please take a look also at our docs regarding a specific platform:


If you dont want to manually install Fusio you can take a look at our cloud platform which you can use to directly run a Fusio instance in the cloud.


Fusio contains two parts which can be updated. The backend system and the backend app. The backend app is the Angular application which connects to the backend api and where you configure the system. The backend system contains the actual backend code providing the backend API.


Fusio makes heavy use of composer. Because of that you can easily upgrade a Fusio system with the following composer command.

.. code-block:: text

composer update fusio/impl

This has also the advantage that the version constraints of installed adapters are checked and in case something is incompatible composer will throw an error. It is also possible to simply replace the vendor folder with the folder from the new release. In either case you have to run the following command after you have updated the vendor folder:

.. code-block:: text

php bin/fusio install

This gives Fusio the chance to adjust the database schema in case something has changed with a new release.


All apps can be updated at the Marketplace panel of the backend app. There you can simply use the update button to receive the latest version of the app. In case the Marketplace is disabled you can also download the app directly from our website at:
