About LogicPlot
A free, open-source digital logic simulator that runs entirely in your browser.
Drag gates, flip-flops, multiplexers, memories and more onto the canvas, wire them up, and watch signals propagate live. Build sub-circuits and reuse them, plot timing diagrams, run testbenches, generate circuits from truth tables, convert to and from Verilog, and export your work as high-resolution images.
Nothing you build leaves your machine. There are no accounts and no server: projects are saved and loaded as files, so you keep full control of your designs.
Inspiration
Inspired by Logisim and CircuitVerse, LogicPlot grew out of the open-source CircuitVerse simulator, whose approachable, education-first design shaped this project. LogicPlot builds on that foundation as an independent, standalone tool. The upstream license notices are kept on the Licenses page.
Get started
Open the simulator and drop your first gate, or start with the Getting Started guide in the documentation.
