esmini
A minimalistic simulator for playing and visualizing traffic scenarios defined in the OpenSCENARIO XML format.
What is esmini?
esmini (Environment Simulator Minimalistic) is an open-source player and library for traffic scenarios defined in the OpenSCENARIO XML format. It simulates dynamic traffic maneuvers on static road networks described in OpenDRIVE, providing a lightweight tool for testing and visualizing driving scenarios. It addresses the need for a portable, integrable simulator to explore and standardize automotive simulation data formats.
Automotive software developers, simulation engineers, and researchers working on ADAS testing, driving scenario validation, or virtual testing platforms that utilize OpenSCENARIO and OpenDRIVE standards.
Developers choose esmini for its minimalistic, portable design and straightforward integration into custom applications via its C++ API, Unity plugin, or Python bindings. It offers a focused implementation of OpenSCENARIO XML support with OSI data export, making it a practical tool for scenario playback and simulation prototyping.

Use Cases
Best For
- Prototyping and testing OpenSCENARIO XML driving scenarios
- Integrating a lightweight scenario player into custom simulation frameworks
- Visualizing OpenDRIVE road networks with dummy traffic
- Exporting OSI ground truth data for sensor model testing
- Running driving scenarios in Unity for immersive simulation
- Educational exploration of ASAM OpenSCENARIO and OpenDRIVE standards
Not Ideal For
- Projects requiring full OpenSCENARIO XML v1.0-1.3 compliance, as esmini's feature coverage is limited and slowly evolving.
- High-fidelity simulations with advanced physics or photorealistic graphics, since esmini prioritizes portability over visual fidelity.
- Teams using OpenSCENARIO DSL format, as esmini has no plan to support it and only works with XML.
- Enterprises needing vendor-backed support and frequent updates, given its community-driven, minimalistic development model.
Pros & Cons
Pros
Runs on Windows, Linux, macOS, and Android with pre-built binaries, making it easy to deploy across diverse systems for simulation testing.
Offers a C++ API, Unity plugin, and Python bindings, allowing seamless incorporation into custom applications or frameworks like Unity for immersive simulations.
Populates and exports Open Simulation Interface ground truth data via UDP, files, or API, supporting sensor model testing and co-simulation workflows.
Designed as a minimalistic tool with shared libraries, ensuring low overhead and easy integration into existing simulation platforms without heavy dependencies.
Cons
Only implements a subset of OpenSCENARIO XML features, with coverage growing slowly based on contributions, which limits scenario complexity and compliance.
Excludes OpenSCENARIO DSL format, forcing users to work exclusively with XML, which may not align with modern scripting or editor-based workflows.
The included viewer is minimalistic and lacks advanced graphics or physics, making it unsuitable for high-fidelity simulations requiring realistic rendering.
