The LynxOS RTOS is a real-time operating system from Lynx Software Technologies (formerly "LynuxWorks"). Sometimes known as the Lynx Operating System, LynxOS features full conformance and, more recently, compatibility. LynxOS is mostly used in real-time , in applications for , /ref> and telecommunications. As such, it is compatible with military-grade security protocol such as , a popular TLS/SSL library.

The first versions of LynxOS were written in 1986 in Dallas, Texas, by Mitchell Bunnell and targeted at a custom-built Motorola 68010-based computer. The first platform LynxOS ever ran on was an with cross development done on an Integrated Solutions UNIX machine. In 1988-1989, LynxOS was ported to the Intel 80386 architecture. Around 1989, ABI compatibility with System V.3 was added. Compatibility with other operating systems, including Linux, followed.

Full Memory Management Unit support has been included in the kernel since 1989, for the reliability of protected memory and the performance advantages of virtual addresses. The architecture is also supported, and in February 2015 Lynx announced planned support for the Cortex A-family.

LynxOS components are designed for absolute determinism (hard real-time performance), which means that they respond within a known period of time. Predictable response times are ensured even in the presence of heavy I/O due to the kernel's unique threading model, which allows interrupt routines to be extremely short and fast.

Lynx holds an expired patent on the technology that LynxOS uses to maintain hard real-time performance. was granted to Lynx November 21, 1995: "Operating System Architecture using Multiple Priority Light Weight kernel Task-based Interrupt Handling."

In 2003, Lynx introduced a specialized version of LynxOS called LynxOS-178, especially for use in avionics applications that require certification to industry standards such as DO-178B.

The newsgroup comp.os.lynx is devoted to discussion of LynxOS.
