Gnash is a GNU Flash movie player. Previously, it was only possible to play flash movies with proprietary software. While there are some other free flash players, none support anything beyond SWF v4. Gnash is based on GameSWF, and supports many SWF v7 features.

The main developer's web site for Gnash is located on the Free Software Foundation's Savannah project support server. This site allows you to file bugs, or view the sources in CVS.

Gnash can run standalone to play flash movies.
Browser plugin
Gnash can also run as a plugin from within most Mozilla derived browsers, such as Firefox. Gnash also has support for Konqueror.
SWF v7 compliant
Gnash can play many current flash movies.
XML Message server
Gnash also supports an XML based message system as documented in the Flash Format specification.
High Quality Output
Gnash uses OpenGL for rendering the graphics on the desktop, and AntiGrain (AGG) for embedded framebuffer only devices.
Free Software
Gnash is 100% free software. For more information on the GPL, go to the Free Software Foundation web site.
Better Security
Gnash pays extra attention to all network connections, and allows the user to control access.

Downloading Gnash

Gnash is being actively developed at the moment. Therefore, although many features work, not all movies play successfully. The the second alpha release message describes the functionality you can expect.

Gnash releases can be found in the subdirectory /gnu/gnash/ on your favourite GNU mirror. Win32 users can download an executable based on a CVS snapshot. NOTE: these are unsupported executables as they are based on a CVS snapshot! Please DO NOT file bug reports on these executables!

CVS Access to Sources

The latest gnash development sources are available via anonymous CVS. Use the following commands to check them out (just hit return when you are prompted for the password):

export CVS_RSH="ssh"
cvs -z3 co gnash

For more detailed information on CVS usage at, read CVS Usage at You can also browse the sources.

If you cannot use ssh because you only have access to the internet through a proxy, you can still get the latest version from a directory of daily cvs snapshots on the web.

The rough draft of the manual describing the most recent release (0.7.2) is available in a variety of formats.

A snapshot of the current CVS revision of the manual in HTML is also available. Alternately, you may build the documentation from your checkout. Please refer to the instructions in the current manual for instructions on how to do this.
