The LTspice circuit simulator is an educational and reference tool that is a member of the circuit simulators genre. According to the product description, it is a “high performance Spice III simulator, schematic capture and waveform viewer with enhancements and models for easing the simulation of switching regulators.” This is one of the most important selling factors it has. In place of LTspice, there are approximately a dozen alternative applications that are compatible with a range of operating systems. These platforms include of Android, Windows, Linux, and Mac computers, as well as web-based and online platforms. Circuit JS, which is not only free but also open source, is now the most appropriate choice because it can be used by anybody.
In terms of the characteristics they offer, QUCS, OpenModelica, Altium Designer, and Xcos are a few additional exceptional applications that compete favorably with LTspice. However, CAD Software and Electronic Design Automation Tools are additional viable alternatives to LTspice that should be considered as potential replacements. The most common alternative to LTspice is something called a Circuit Simulator. You can use any or all of these as criteria for the filter if you are looking for a particular feature of LTspice or if you want to reduce the number of options available to you.
Why Look for LTspice Alternatives?
Even though LTspice is a strong tool, there are a number of good reasons why you should consider looking into other options. It’s possible that you’re looking for a piece of software that provides a unique user interface, heightened functionality, or compatibility with specific operating systems. In addition, some engineers believe that the best way to meet the many requirements of simulation is to have a toolkit that has a wide variety of tools. In the sections that follow, we will discuss many aspects that should be taken into account while selecting an appropriate alternative for your circuit simulation attempts.

Questions and Answers
Unfortunately, LTspice is not open source, does not support scripting, and does not let users to contribute their own code models to the program. NGSPICE is the way to go if you require these more advanced choices, however not many people do or care about these things.
LTSpice is a piece of software that excels at simulating electronic circuits and power electronics in the shortest amount of time possible. The word OrCAD refers to the entire software package that is used to assist in the design of printed circuit boards (PCBs). Within the OrCAD suite, the tool known as OrCAD capture is the one that enables users to ‘draw’ schematics.
