About Qucs-S
Qucs-S is a fork of the Qucs circuit simulator that keeps its schematic editor and result plotting but runs simulations through SPICE engines. The Windows installer bundles Ngspice, so you can draw a circuit, simulate it and view the results in one program.
Releases come regularly, most recently version 26.1.1. It is packaged for Debian, Ubuntu, Fedora and openSUSE, and available as an AppImage, on Flathub, through FreeBSD ports, as a Windows installer or portable zip, and through Homebrew on macOS.
Strengths
- Graphical schematic entry for SPICE simulation
- Windows installer bundles Ngspice
- Packaged for many Linux distributions, Windows and macOS
- Regular releases
Limitations
- Simulation only; no PCB layout
- macOS install goes through Homebrew

Alternatives to Qucs-S
Compare allSoftware that can replace Qucs-S for an important use case, and what changes if you switch.
LTspice
A free SPICE circuit simulator with schematic capture and a waveform viewer, from Analog Devices.
LTspice is a free, closed-source SPICE simulator from Analog Devices with its own schematic capture and waveform viewer, running on Windows only rather than across three platforms.
ngspice
An open-source SPICE simulator for analog, digital and mixed-signal electronic circuits described as netlists.
ngspice is the SPICE engine used directly from the command line with netlists, offering mixed-signal simulation but no graphical schematic entry like Qucs-S provides.
Proteus Design Suite
Electronics design software combining schematic capture, circuit and microcontroller simulation, and PCB layout.
Proteus Design Suite adds microcontroller firmware simulation and PCB layout to schematic capture, but it is commercial, closed source and runs only on Windows.
