There is a **[demo site](https://demo.firefly-iii.org)** with an example financial administration already present. You can use Docker, Heroku or Sandstorm.io (see below) to quickly setup your own instance.
You can use docker-compose to [set up your personal secure](https://firefly-iii.org/using-docker.html) Firefly III environment. Advanced users can use the Dockerfile directly.
You can install Firefly III on any Linux or Windows machine. You'll need a web server (preferrably on Linux) and access to the command line. Please read the [installation guide](https://firefly-iii.org/using-installing.html).
You can find Firefly III in [the Sandstorm.io marketplace](https://apps.sandstorm.io/app/uws252ya9mep4t77tevn85333xzsgrpgth8q4y1rhknn1hammw70). You can run it on your own installation or on Oasis.
- Firefly runs on your own server, so you are fully in control of your data. Remember, there is no such thing as "the cloud", it’s just somebody else’s computer!
