Hello everyone,
Today is an important milestone for the project. After many months of work, I'm happy to announce that Open Sim Relay (OpenSR) Early Access is now available for everyone .
OpenSR is the official successor to Ledsmaster and the old SLIMax Manager Pro software . This is not just another version or a simple update; it is a fresh start and a "legacy project" that consolidates everything I have developed for the sim racing community since 2007 into a single, powerful platform .
The philosophy behind OpenSR is simple: "Any Game In. Any Hardware Out."
What makes OpenSR different?
Unlike previous tools, OpenSR is built on a modular, plugin-based architecture . By using IN (Source) plugins to capture telemetry and OUT (Destination) plugins to drive hardware, the system is incredibly lightweight and flexible . Whether you are using digital dashboards, motion platforms, LEDs, or even custom IoT and robotic systems, OpenSR is designed to be the invisible bridge that connects your virtual data to the real world .
Completely Free & Community-Driven
Most importantly, OpenSR is now completely free. There are no licenses, no registration, and no activation process for the core software . Just download it, install it, and enjoy it.
For those who wish to support the project, I have introduced a Pro Performance Mode (PPM). While the free version operates at 30 Hz (which is sufficient for most setups), signing in as a donor unlocks the game’s native telemetry rate, typically between 60 Hz and over 500 Hz . This is my way of rewarding those who have helped this project grow. Obviously, all registered users since 2009 can access PPM by simply signing into the app.
Join the Journey
The Early Access version already supports the majority of previously supported devices and all major sim racing titles . As development continues, more games, plugins, and features will be added.
We've created dedicated forum sections for OpenSR. Whether you have a bug to report, an idea for a feature, or simply want to share your experience, your feedback is essential during this Early Access period .
I’d like to take a moment to thank everyone who has supported our projects since 2009. This community is the reason EKSIMRacing continues to exist. Many of you have been here for years, testing early builds, reporting bugs, and encouraging this evolution. I truly appreciate every one of you.
OpenSR is now a genuine community project. Whether you contribute documentation, write plugins, report bugs, or support the project with a donation, every bit of help makes a difference .
This release is only the beginning. I'm looking forward to building the future of OpenSR together with all of you.
Thank you again. Now, go
download OpenSR, give it a try, and let me know what you think!
Cheers,
z
