Open source

Name	Language	Type	Last Updated	License	Description
CPN Tools	BETA	Application	February 1, 2015 (v4.0.1)[15]	GPLv2	A tool to analyse logistics/queuing models in all types of applications.
DESMO-J	Java	Library	November 30, 2015 (v2.5.1c)[16]	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.[17]
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.[18] "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."[19] "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." [20]
PowerDEVS	C++	Application	September 18, 2013 (v933)[21]	AFL, GPLv2	An integrated tool for hybrid systems modeling and simulation based on the DEVS formalism.
Ptolemy II	Java	Library	December 17, 2014 (v10.0.1)[22]	BSD	A software framework supporting experimentation with actor-oriented design.[22]
SIM.JS	JavaScript	Library	January 16, 2012 (v0.26)[23]	LGPL	SIM.JS is a general-purpose Discrete Event Simulation library written entirely in JavaScript. Runs in browser and a GUI-based modeling tool is supported.
SimPy	Python	Library	November 12, 2023 (4.1.1)[24]	MIT	SimPy is a process-based discrete-event simulation framework based on standard Python.[25]
Simula	Simula	Language	June 1, 1967		A programming language designed specifically for simulation.
