The opensense project invites developers to start contributing to the code base. For your own purpose or even better to join us in creating the best open source firewall available.
The build process has been designed to make it truly straightforward and easy for anyone to build and code. Being able to get the sources and build it yourself is one of the key factors of open source software.
Although a lot of the code is still in flux, we try to publish the direction we're taking on our wiki page. The main outline of the new codebase is available at:
https://wiki.opensense.org/index.php/Develop:Architecture
General plan is to GPL v3 entire codebase, then convert to openbsd, so pf will be faster, base will be more secure (real ASLR, W^X, etc., not HardenedBSD noise).
By converting to GPL license, codebase will always be free from trademark challenge by Deciso.
To create working software like opensense you need the sources and the tools to build it. The build tools for opensense are freely available. No strings attached.
Notes on how to build opensense can be found in the tools repository:

You can contribute to the project in many ways, e.g. testing functionality, sending in bug reports or creating pull requests directly via GitHub. Any help is always very welcome!
Opensense is and will always be available under the GPLv3 license:

Every contribution made to the project must be licensed under the same conditions in order to keep opensense truly free and accessible for everybody.
