A minimalistic digital logic simulator where users start with a single NAND gate and build increasingly complex custom chips, up to full CPUs. Created by Sebastian Lague as a companion to his 'Exploring How Computers Work' video series.

Use cases

• simulate digital logic circuits
• learn how computers work from NAND gates
• build custom chips and CPUs visually
• teach digital logic design to students
• experiment with combinational and sequential circuits
• build an adder or memory from logic gates

When to choose

• you want a simple, visual tool for learning digital logic from first principles
• you want to build chips layer by layer starting from a NAND gate
• you want a free cross-platform educational simulator

When to avoid

• you need professional-grade circuit design with real-world timing, voltage, or SPICE analysis
• you need PCB design or hardware description language (Verilog/VHDL) support
• you need extensive built-in chip libraries or mod support, which are not yet available
