Haiku WebKit
The Haiku Operating system is an open-source rewrite of BeOS. WebKit is used for the built-in WebPositive browser, and will be soon made available in the BeAPI for other applications willing to embed HTML content or use other Web technologies.
Sourcecode
http://github.com/haiku/haiku-webkit
Status
The port used to be part of the main WebKit sources, but was removed for lack of a build bot and maintainers able to keep it up to date. It is hosted elsewhere until it is updated again and ready for merging.
Building
Follow README.markdown instructions in the source tree root.
Features
Uses the BeAPI (http://www.haiku-os.org/legacy-docs/bebook/ , http://api.haiku-os.org ) for UI and Network. Relies on POSIX for most of the low-level support (threads, etc.)
