OpenBinder is a system for inter-process communication.[http://www.angryredplanet.com/~hackbod/openbinder/docs/html/ OpenBinder] website It was developed at Be Inc. and then Palm, Inc.Eugenia Loli-Queru, [http://www.osnews.com/story.php/13674/Introduction-to-OpenBinder-and-Interview-with-Dianne-Hackborn/ Introduction to OpenBinder and Interview with Dianne Hackborn], OSNews, 14 February 2006. and was the basis for the Binder frameworkAleksandar Gargenta, Deep Dive into Android IPC/Binder Framework, [https://archive.today/20130411080916/http://marakana.com/s/post/1392/Deep_Dive_Into_Binder_Presentation.htm%23slide-4 What is Binder?], 17 February 2013 now used in the Android operating system developed by Google.Ben Leslie, [http://benno.id.au/blog/2007/11/18/android-runtime-strace Android: strace runtime], Benno’s website, 18 November 2007.

OpenBinder allows processes to present interfaces which may be called by other threads. Each process maintains a thread pool which may be used to service such requests. OpenBinder takes care of reference counting, recursion back into the original thread, and the inter-process communication itself. On the Linux version of OpenBinder, the communication is achieved using ioctls on a given file descriptor, communicating with a kernel driver.

The kernel-side component of the Linux version of OpenBinder was merged into the Linux kernel mainline in kernel version 3.19, which was released on February 8, 2015.{{cite web
