Vrapimit

Vrapimit is an open-source software library designed to emulate virtual reality (VR) hardware interfaces and associated application programming interfaces (APIs) for development, testing, and automation. The project provides a lightweight framework to simulate input devices such as head-mounted displays, motion controllers, and tracking systems, as well as the software APIs used by VR applications. The goal is to enable developers to build and test VR software in environments where physical hardware is unavailable, costly, or impractical to use.

Vrapimit typically offers modular components, including an input device simulator, an API shim layer, and an event-driven emulator, along with configuration tools and scripting support for reproducing complex interaction scenarios. By abstracting hardware specifics, it allows testing of application logic, user interaction flows, and performance characteristics without real devices. It may also support recording and replay of VR sessions for regression testing.

The project adopts an open-source license and welcomes contributions from the community. Typical users include game studios, research teams, and software developers building VR experiences, simulations, training applications, or research prototypes. Integration is usually achieved by wiring the emulator into the development stack and providing mock data streams to VR applications or engines.
