## Open source

| Name | Language | Type | Last Updated | License | Description |
| CPN Tools | BETA | Application | February 1, 2015 (v4.0.1) | GPLv2 | A tool to analyse logistics/queuing models in all types of applications. |
| DESMO-J | Java | Library | November 30, 2015 (v2.5.1c) | Apache 2.0 | A framework for discrete-event simulation in Java, supporting hybrid event/process models and providing animation in 2D and 3D. |
| gem5 | C++ | Application | August 8, 2024 | BSD | The gem5 simulator is a modular platform for computer-system architecture research, encompassing system-level architecture as well as processor microarchitecture. |
| JaamSim | Java | Application | September 18, 2024 (v.2024-07) | Apache 2.0 | JaamSim is a fast and scalable discrete-event simulation software that includes a drag-and-drop user interface, interactive 3D graphics, input and output processing and model development tools and editors. "Out of all the OS DES projects we reviewed, JaamSim is the one with the most impressive 3D user interface that can compete against COTS DES software. (...) The fact that a non-expert user can just download and test the software in a few minutes is something that is a scarce attribute in OS projects and especially in the DES domain. (...) It is the only tool we found that is clearly industry driven (...) and this may have led to more consistent motivation and funding." "JaamSim provides everything which is necessary to model typical planning tasks in production and logistics and proves as a real alternative to commercial DES tools." |
