For players
Play without the hassle.
Use a shortcut to open a ready-made session, with no terminal or manual changes. Players can enjoy the result without interacting with OmsiLaunch directly.
OPEN SOURCE FOR OMSI 2 BY THE COMMUNITY
Integration
starts here.
OmsiLaunch is an open-source session control and orchestration layer for OMSI 2.
A flexible infrastructure for defining, preparing, and managing OMSI 2 sessions with more possibilities.

WHO IT IS FOR
For players, creators, and developers.
For creators
Ready-to-share profiles.
Create and distribute Predefined Session Profiles with their own settings, presets, and assets for maps, tools, and other content.
For developers
Integrate and automate.
Use the CLI, DLL/API, launchers, external tools, multiplayer, and automation to control sessions with your existing infrastructure.
PREDEFINED SESSION PROFILES
Session profiles for every need.
Predefined Session Profiles let you save and reuse complete sets of settings, add-ons, and adjustments, making it easier to create and share experiences.
Each profile can include splash screen assets and set policies for internet texture usage during the session.
RMG Leste is an upcoming map that ships with Predefined Session Profiles built in, making different setups and experiences easy from day one.
Available profiles
01Low-end PCLightweight setup, ideal for modest machines.
02Mid-range PCA balance between quality and performance.
03High-end PCMaximum quality for the best experience.
Usage example (command line)
OmsiLaunchW.exe \/predefined-profile:rmg-leste \/predefined-profile-index:1 \/new
Simple, direct, and powerful. The same profile can be used from a shortcut or by your application.
WHAT IS OMSILAUNCH?
A control layer for OMSI 2 sessions.
OmsiLaunch is an open-source control and orchestration layer designed for OMSI 2. It integrates tools, manages processes, handles configuration, and prepares the environment for a consistent, flexible experience.
It is not a graphical launcher. OmsiLaunch can be used by your own interface, scripts, or integrations. Control is the core. Flexibility is the goal.
Open source
Built for the community.
Modular and extensible
Works with different tools and workflows.
More than starting the game
A complete session-orchestration layer.
Built for possibilities
For what exists today — and what comes next.
CORE CAPABILITIES
Session definition
Define the map, entry point, situation, date, time, vehicle, and other parameters in a structured way.
Controlled startup
Prepare the state and start OMSI 2 without relying on UI click automation.
Transparent execution
Run through OmsiLaunchW.exe, shortcuts, launchers, or applications with no visible terminal.
Predefined sessions
Predefined Session Profiles and shareable presets for community content.
Safe configuration
Temporary changes tied to the session, preserving and restoring the environment following the transactional lifecycle.
Recovery and reliability
Diagnostics, lifecycle, recovery, and failure handling are part of the session design.
RUNTIME MODULES
Extensions that live inside the session.
Runtime Modules are optional components that OmsiLaunch loads together with an OMSI 2 session. Each module describes in a manifest what it does and what it needs, and follows the session lifecycle.
Optional and described
Each module comes with a manifest that says what it does, what it needs and how to configure it.
Tied to the session
Activation and settings can come from a profile or the command line, session by session.
Failure under control
Each module defines what happens if it fails: end the session, disable the module or carry on without it.
The first example will be openHUD, planned for the next betas. Read the concept in the documentation.
ARCHITECTURE AND FLOW
Connecting tools, people, and the game.
OmsiLaunch is designed to be an integration point between different ways of using it, serving everyone from players to developers.
