Valencia's Simple Tasker (VSTa) is an operating system with a microkernel architecture, with all device drivers and file systems residing in userspace mode. It mostly complies with the Portable Operating System Interface (POSIX), except where such compliance interferes with extensibility and modularity. It is conceptually inspired by QNX and Plan 9 from Bell Labs. Written by Andy Valencia, and released under a GNU General Public License (GPL). As of 2020, the licensing for VSTa is Copyleft.

VSTa is no longer developed. A fork, named Flexible Microkernel Infrastructure/Operating System (FMI/OS), did not make a release.[1]
