Fusio is an open source API management platform which helps to build and manage REST APIs. It can help you with the following use cases:
Fusio provides a developer portal where developers can register to access your API.
Fusio can be used as gateway to your internal API and microservices.
Fusio allows you to build API endpoints without coding knowledge.
For more complex use cases you can use Fusio also as framework to build complete APIs from scratch.
API management and features
Fusio is an API management platform where you can configure routes which execute specific actions. An action triggers your business logic, it is like a controller in a classical framework, you can also think of it like a serverless lambda function, which can be executed on a route call or via RPC. Fusio covers many aspects of the API management life cycle so that you can concentrate on writing the actual business logic of your API. Please take a look at our documentation website for more information. The following feature list gives you a first overview:
- OpenAPI generation
Fusio generates automatically an OpenAPI specification for the defined routes
- SDK generation
Fusio can automatically generate a client SDK for your API based on the defined schema
- Subscription support
Fusio contains a subscription layer which helps to build pub/sub for your API
- Rate limiting
Fusio provides a way to rate limit requests based on the user or app
Fusio uses OAuth2 for API authorization
- RPC support
Fusio provides RPC support, every action which you create can be also called via JsonRPC
Fusio provides a simple payment system to charge for specific routes
Fusio uses the TypeSchema to automatically validate incoming request data
Fusio monitors all API activities and shows them on a dashboard
- User management
Fusio provides a developer app where new users can login or register a new account through GitHub, Google, Facebook or through normal email registration
Since it is difficult to work with an API only app Fusio provides apps which help to work with the API. Mostly apps are
simple JS apps, which work with the internal API of Fusio. You can see a list of all available apps at our
marketplace. You can install such an app either through a CLI command i.e.
php bin/fusio marketplace:install fusio or through the backend app.
All apps are installed to the
apps/ folder. You need to tell Fusio the public url to the apps folder at the
file by defining the
FUSIO_APPS_URL variable. Depending on your setup this can be either a custom sub-domain like
https://apps.acme.com or simply the sub folder
The backend app is the main app to configure and manage your API. The installer automatically installs this app. The app
is located at
Fusio provides a VSCode extension which can be used to simplify action development. This means you can develop every action directly inside the VSCode editor.
APIgen is a code generator tool which allows you to generate code based on Entity or OpenAPI definitions. The tool generates then all routes, schemas and actions. You can then either download or deploy the generated code to a remote instance.
The cloud service allows you to create a Fusio instance in the cloud. It really simplifies the usage of Fusio since you can create and manage an instance through a simple web interface.
It is possible to install Fusio either through composer or manually file download.
composer create-project fusio/fusio
You can either manually install Fusio with the steps below or you can also use the browser based installer at
public/install.php. Note because of security reasons it is highly recommended removing the installer script after the
- Adjust the configuration file
Open the file
.envin the Fusio directory and change the
FUSIO_URLto the domain pointing to the public folder. Also insert the database credentials to the
FUSIO_DB_*keys. Optional adjust
FUSIO_APPS_URLto the public url of the apps folder (in case you want to use apps).
- 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".
- Install backend app
To manage your API through an admin panel you need to install the backend app. The app can be installed with the following command
php bin/fusio marketplace:install fusio
You can verify the installation by visiting the
FUSIO_URL with a browser. You should see an API response that the
installation was successful.
In case you want to install Fusio on a specific database you need to adjust the
driver parameter at the
sqlsrv: Microsoft SQL Server
sqlanywhere: SAP Sybase SQL Anywhere
Alternatively it is also possible to setup Fusio through docker. This has the advantage that you automatically get a complete running Fusio system without configuration. This is especially great for testing and evaluation. To setup the container you have to checkout the repository and run the following command:
docker-compose up -d
This builds the Fusio system with a predefined backend account. The credentials are taken from the env variables
FUSIO_BACKEND_PW in the
docker-compose.yml. If you are planing to
run the container on the internet you must change these credentials.
Please check out our official documentation website where we bundle all documentation resources: https://docs.fusio-project.org/
This should give you a first overview about all important repositories which belong to the Fusio project:
Contains the main Fusio repository where we collect and discuss all ideas and issues
Contains the backend API implementation of Fusio. This is the place if you like to change the internal API of Fusio
Contains the CLI client for Fusio, it is automatically included in every Fusio installation but you can also run the CLI client standalone. It allows you to directly interact with the API and to deploy specific YAML configuration files
Contains all Fusio models automatically generated via TypeSchema. This repository helps if you want to work with the Fusio API since you can use the same model classes which we also use at the backend
Contains mostly interfaces which are also needed by adapters. This repository is very stable and there are few changes
Page which shows all available adapters. An adapter can extend Fusio by providing i.e. custom Actions or Connections to different services. I.e. we have an adapter MongoDB which helps to work with a MongoDB
Contains a Docker-Image to run Fusio, it helps to quickly create a Fusio instance in the cloud. You can find it also directly on DockerHub
Contains the Fusio backend app which you can use to configure your API. This is the place if you like to change or improve the backend app
Contains a developer portal app where external developers can register to use your API
Contributions to the project are always appreciated. There are many options available to improve the project (which is not limited to coding). The following list shows some ways how you can participate:
The backend API is the core of the system developed in PHP, which provides the basic functionality of Fusio. This is the place to develop new core features and improvements.
An adapter is a plugin to the Fusio system which can be used to connect to other remote services. I.e. you could create
a new adapter which speaks to a specific API or other remote service. This is easy to develop since you can build it in
a separate repository. Please use the keyword
fusio-adapter in your
composer.json file so that adapter gets listed
automatically on our website.
This is the AngularJS app which is used as GUI to control the backend. It is the main app to improve the Fusio backend. But you are also free to develop new apps for special use cases which talk to the internal API of Fusio.
We have a high PHPUnit test case coverage and also automatic end-to-end AngularJS tests using protractor and selenium. Beside this it is always great if users checkout the current master version of the project and try to test every aspect of the system. In case you have found an issue please report it through the issue tracker.
We want to create a system which is easy to use also by novice users. To enable everybody to start using Fusio we need a great documentation. We have bundled all documentation at our documentation website please feel free to adjust or contribute new documents in case you think something is missing or wrong.
If you are a blogger or magazine we would be happy if you like to cover Fusio. Please take a look at the Media section of our About Page to download the official icon set. In case you have any questions please write us a message directly so we can help you to create great content.
If you are a company or freelancer and want to get detailed information how you can use Fusio you can contact us for consulting. In the workshop we try to find the best way how you can use/integrate Fusio also we try to explain the functionality and answer your questions.
