Icecast or Shoutcast: what is the difference?
Almost every internet radio station runs on Icecast or Shoutcast. For your listeners it makes little difference: both deliver a stream that plays in browsers, apps and smart speakers. For you as a broadcaster, there are some differences.
Icecast at a glance
Icecast is open source and developed by the Xiph.Org Foundation. You can use it for free, commercially too, and it runs on Linux, Windows and macOS. An Icecast server works with mountpoints: every stream has its own address, such as /live or /hq. That makes it easy to offer a high and a low quality side by side. Besides MP3 and AAC, Icecast also supports open formats such as Ogg and Opus.
Shoutcast at a glance
Shoutcast is the older of the two and is closed software from a commercial company. The server software (DNAS) is a free download; extra services, such as detailed statistics and ways to earn money with advertising, come with paid plans. A Shoutcast server can host several streams using stream IDs and supports MP3 and AAC. A well-known advantage is the Shoutcast directory, where listeners can find your station.
The differences in short
- Cost: Icecast is completely free; with Shoutcast the basics are free and you pay for extras.
- Formats: both do MP3 and AAC; Icecast also handles Ogg and Opus.
- Multiple streams: Icecast via mountpoints, Shoutcast via stream IDs. In practice both work well.
- Statistics: both show the listener count and the current song on a status page. For detailed charts you need extra tools with either.
- Hosting: almost every streaming host offers both, often through a control panel such as AzuraCast or Centova Cast.
Tip: StreamTop works with both. Enter your stream link when you sign up; we read the listener count and current song ourselves and turn them into charts.
Which one should you choose?
If you are just starting and want minimal costs and maximum freedom, Icecast is the logical choice. If you rent a package from a host, simply pick what they offer by default; for a new station the differences are small. More important than the server are a stable connection from your studio, a sensible bitrate and a schedule that keeps listeners coming back.
