Patchwork is a free, web-based patch tracking system designed to facilitate the contribution and management of contributions to an open-source project. It is intended to make the patch management process easier for both the project's contributors and maintainers.

Patches that have been sent to a mailing list are 'caught' by the system, and appear on a web page. Any comments posted that reference the patch are appended to the patch page too. The project's maintainer can then scan through the list of patches, marking each with a certain state, such as Accepted, Rejected or Under Review. Old patches can be sent to the archive or deleted.

Currently, Patchwork is being used for a number of open-source projects, mostly subsystems of the Linux kernel and FFmpeg. Although Patchwork has been developed with the kernel workflow in mind, the aim is to be flexible enough to suit the majority of community projects.
