Logisim is described as 'Educational tool for designing and simulating digital logic circuits. With its simple toolbar interface and simulation of circuits as you build them, it is simple enough to facilitate learning the most basic concepts related to logic circuits' and is a circuit simulator in the education & reference category. There are more than 10 alternatives to Logisim for a variety of platforms, including Windows, Linux, Mac, Web-based and Self-Hosted apps. The best Logisim alternative is Digital, which is both free and Open Source. Other great apps like Logisim are Flowgorithm, BOOLR, Hradla and Logisim Evolution.


Flowgorithm is a free application that helps you create programs using simple flowcharts.








Logical Network Editor that runs in your browser. Currently supports basic gates using boolean logic, smart wire routing and network simulation. The simplicity allows to quickly understand the principles of binary logic and simple circuit design.

Logisim is an educational tool for designing and simulating digital logic circuits. It has been originally created by Dr. Carl Burch and actively developed until 2011. After this date the author focused on other projects, and recently the development has been officially stopped...



A minimalistic digital logic simulator. You start with an AND and a NOT gate, and from there you can build whatever you want.


Integrated schematic editor and simulator. Dynamic analysis updates waveforms and curves as you edit Native digital simulator Worst Case analysis to find the statistical and extreme limits of performance Smoke Analysis to assess how close the circuit is to violating maximum opera.




Digital Logic Design is a Software tool for designing and simulating digital circuits. A circuit is composed of gates, flip-flops, standard combinational and sequential components and Modules. A number of gates, flip-flops and standard combinational and sequential components are...





Explore Digital circuits online with CircuitVerse. With our easy to use simulator interface, you will be building circuits in no time. CircuitVerse contains most primary circuit elements from both combinational and sequential circuit design.



Atanua is a real-time logic simulator, designed to help in learning of basic boolean logic and electronics. It uses OpenGL hardware-accelerated rendering and a custom UI designed for a fast workflow and a very low learning curve, letting the students concentrate on learning the...





Its interface and concepts are close to Logisim's, so one can directly start to use it. It can also support much faster simulation than what Logisim offers.
