Free Flash Media Server Alternatives

Today, many projects are built around real-time communication (text, voice or video) like collaboration tools, chat applications and much more.

Adobe® Flash® Media Server is probably the most widely used solution for streaming video and real-time communication. It is a stable product that has been experienced for years and used by many companies.

On the other hand, if you're looking for a free solution to stream your media, there are so few alternatives that you can rely on.

And here are 2 of them (if you know any other free and solid ones, please share):


Red5 Flash Server

Red5 is an open source Flash server that is written in Java and supports:

  • streaming audio/video (FLV, MP3, F4V, MP4, AAC, M4A)
  • recording client streams (FLV only)
  • shared objects
  • live stream publishing (Sorenson, VP6, h.264, MP3, AAC and more)

It has installers for OSX and Windows. Also, it can be downloaded as a zip file to be used in any OS.

Mammoth Server

Mammoth Flash Server

Mammoth is also an open source Flash streaming server that is built with C++ and can run on Windows and *nix OSs.

It can stream all Flash codecs like h263, h264, mp3, vp6, speex, nellymoser, etc.

By using FFmpeg it has has container support for most formats: mov, flv, mkv, mp3 and more.

The server is still in alpha phase but very promising.


If you know any other free and solid alternatives, please share and we'll be happy to add them to the list.

  • These work is very useful for many users . Thanks so much…

    We evaluated using Red5 but with our VPS server it just consumed way too many resources. We decided rather to go with SimpleCDN ( to stream the video. Works great with flowplayer, is very simple to setup, and is ridiculously cheap!

  • Not sure how to implement this sort of flash server. It looks promising.

    Red5 last version (0.8) is very hard to use for developing something new from server side, it uses spring and nobody pays attention to write a good tutorial, all tutorials is out-dated.

    There are many rtmp servers, like python rtmpy which I liked but unfortunately nothing is compared with the libraries of the server side actionscript and the ease of use, and these streaming servers can be used only if you pay. I hope one day red5 be a better alternative, but right now you can’t even find how to setup easily with eclispe and write a simple playlist.

    If on the other hand, you only care for client side use and use of streaming abilities, red5 is a good solution.

  • Have a look at these also:

  • iongion

    really strange commenting system, does not tell you anything after submission and the post does not appear

  • Opera has Opera Unite with a application to do this.

  • You could use two mods for apache which allows pseudo streaming, I use them and no problems so far 🙂

    Or you could use cherokee webserver, which has built in pseudo streaming…

  • Red 5 looks promising. Mammoth looks a little bit new, and with Adobe’s recent announcement regarding the future of Flash, I wonder how much time will be put into getting it to Beta.
