I Built a Free Browser-Based Digital Logic Simulator for Learning Boolean Algebra

Boolean algebra and digital logic are much easier to understand when you can build and test circuits visually. That idea is exactly why I created Boolflow — a free browser-based digital logic simulator for students, self-learners, and anyone teaching or exploring logic design. What Boolflow is Boolflow is an online simulator where you can build and test digital circuits directly in the browser. It is designed for learning and experimentation, especially for topics like: Boolean algebra logic gates combinational circuits flip-flops counters multiplexers simple digital design workflows The goal was simple: make a tool that opens instantly, requires no installation, and helps users move from abstract formulas to visual understanding. Why I built it A lot of learning materials explain Boolean algebra symbolically, but for many people the real understanding appears only when they can: connect gates toggle inputs observe outputs test small circuit ideas compare theory with behavior I wanted
