 ## Platform Services
 
 Horizon is the client-facing RESTful HTTP API server in the platform layer which allows programmatic access to submit transactions and query the network’s historical data. It acts as the interface for applications that want to access the Stellar network. You can communicate with Horizon using an SDK, a web browser, or with simple command tools like cURL.
 
-You do not need to run your own Horizon instance — when you're getting started, you can use the free SDF Horizon instance to access the network — but it is recommended that you do when you’re ready to launch a finished product. Check out how to do so here: [Run Platform Services Tutorial](../run-platform-server)
