CircuitLab

CircuitLab is a browser-based circuit simulator allowing quick schematic capture and interactive SPICE analysis. Users can experiment with analog/digital components, adjusting values on the fly to see real-time simulation results (voltages, waveforms). A collaborative environment supports multi-user edits or teacher-student interactions. Though it’s not a full PCB layout tool, CircuitLab excels at educational contexts and prototyping circuit behavior. Premium plans unlock advanced features, larger circuits, and commercial usage. Its convenience, no installation needed, is popular among electronics educators, hobbyists, and small project teams.
