What is OSFlash?

OSFlash is a watering hole for open source Flash developers and users to meet, talk about and contribute to new and existing open source projects for the Flash Platform.

OSFlash supports the development community by providing open source projects with free source code hosting and project management tools as well as a web presence on the OSFlash wiki.

As such, we provide a service that is similar to other sites such as SourceForge but perhaps in a smaller, more intimate setting that is focused on open source projects for the Flash Platform.

(We heard some people think that OSFlash is a project to create an Open Source Flash IDE alternative. OSFlash is not an open-source development project but a collection of tools and resources for open source developers who love the Flash Platform and want to expand its horizons! :)

If you are interested in using or developing open source Flash tools, we invite you to join the OSFlash community. You can start by joining the OSFlash Mailing list, looking at the list of existing Open Source Flash Projects and learning Wiki syntax so you can contribute to this site. You can learn more about this Wiki and read its history on the OSFlash History page.

OSFlash Philosophy

Open Source is good for the Flash Platform.

“Open Source” software is software that you’re free to use, modify, and redistribute. More specifically, see the definition of Open Source as championed by the Open Source Initiative.

The OSFlash community is comprised of members of the Flash Community who use and develop open source on the Flash Platform.

A vibrant, healthy and productive open source community is an essential barometer of the health and success of the Flash Platform. Healthy platforms require a full ecosystem of tools, both closed-source and open-source. Open Source tools and projects also bring new developers into the Flash Platform and lead to increase competition and choice for developers.

To ease the creation of open source tools, the community also documents features of the Flash Platform such as protocols and file formats. It is essential for the core protocols and file formats of the Flash Platform to be open if the platform is to see widespread adoption.

The OSFlash website, mailing lists and source control accounts are free tools and services provided for use by the Flash Community. They are designed in order to enable community members to easily share knowledge and collaborate on open source Flash projects.

What is Open Source?

Read the definition of Open Source from the Open Source Initiative (OSI).

Open Source Flash Projects

OSFlash maintains a comprehensive list of Open Source Flash Projects.

This list is constantly being updated. If you are aware of an open source Flash project that is not on the list, please feel free to add to it. Note: Free does not mean Open Source. Free/commercial tools that are closed-source may be listed if absolutely necessary on the Closed Source Flash Tools page (see guidelines on the page for this.)

If you want a certain open source Flash tool/feature/application and you don’t see it on the list, please make an entry on the OSFlash Wishlist. The wishlist helps developers understand the needs of the community and gives developers direction on what to develop.

Packaging osflash projects

There are no established efforts on this front yet.

There is an idea to start doing some osflash Debian Packaging. If you can help this effort or if you use Debian, please add your support to the page.

Join the mailing list

Get involved! Join the OSFlash Mailing list. Please also make sure to read through the OSFlash Mailing List Archives online to see if your questions have already been answered.

For other open source flash mailing lists please refer to the Mailing Lists page.

Come to IRC

There is an IRC channel #osflash


What tools, features, libraries are you missing while using osflash? Make a note at the wishlist so interested developers can pick a project and try to implement what you need.
