The best free alternative to Simulink is Circuit JS, which is also Open Source. If that doesn't suit you, our users have ranked more than 25 alternatives to Simulink and many of them is free so hopefully you can find a suitable replacement. Other interesting free alternatives to Simulink are Xcos, SimulIDE, Ktechlab and OpenModelica.
This is a javascript electronic circuit simulator. When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage. The gray color indicates ground. A red color indicates negative voltage.
It may be a good alternative to Spice but not simulink, it is for circuits only
Not all applications can be modeled with circuits
Xcos is a graphical editor to design hybrid dynamical systems models. Models can be designed, loaded, saved, compiled and simulated.
SimulIDE is a simple real time electronic circuit simulator. It's intended for general purpose electronics and microcontroller simulation, supporting PIC and AVR. PIC simulation is provided by gpsim and avr simulation by simavr.
KTechLab is an IDE for microcontrollers and electronics. It supports circuit simulation, program development for microcontrollers and simulating the programmed microcontroller together with its application circuit.
OpenModelica – A Free Modelica Environment! OpenModelica is an open-source Modelica-based modeling and simulation environment intended for industrial and academic usage. Its long-term development is supported by a non-profit organization – the Open Source Modelica Consortium (OS.

Great UI, love the HPC in the cloud.
Educational virtual 3D laboratory simulator helps students, teachers, and tutors conduct electrical circuit experiments by providing realistic equipment access anywhere, avoiding availability issues and safety hazards, and enhancing learning with immediate feedback and...
MyOpenLab is a Java-based software, which contains graphic blocks, each one fulfills a specific function and has properties configurable by the user.
Create circuits using the graphical user interface as a quick way of modelling the dynamic system. After you create a circuit you may load this file and simulate the circuit 'dynamically' by changing parameters during the circuit simulation.
GNU Radio is a free & open-source software development toolkit that provides signal processing blocks to implement software radios. It can be used with readily-available low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like...
