Like EasyEDA, but for learning the logic, not laying out the board

EasyEDA is free online PCB design software: a schematic editor for large designs, PCB layout with 2D and 3D views and a Gerber viewer, in the browser with nothing to download or as a desktop client with offline modes. Its pages link straight to PCB prototyping at JLCPCB and component buying at LCSC, and its Standard Edition supports simple circuit simulation. If that is what brought you here, digiwleea is a free, in-browser alternative with a different angle: you build a computer from the transistor up.

What EasyEDA is good at

For turning a circuit into a real board it is a strong, practical tool: free, quick to start in a browser, with a big parts library and a short path from schematic to manufactured PCB. If your goal is a board you can order, it is the right kind of tool. (digiwleea is an independent project, not affiliated with EasyEDA, JLCPCB or LCSC.)

How digiwleea is different

EasyEDA is about drawing and manufacturing a circuit; digiwleea is about understanding how digital logic works. In digiwleea you build logic from CMOS transistors up, wiring gates into adders, latches, registers and RAM and finishing with an 8-bit CPU that you program in assembly, in a guided 40+ level course with an AI tutor (Wleea). Every circuit runs live on a logic simulator that shows each wire as 0, 1 or floating and checks your parts against their truth tables. It does not lay out PCBs, export Gerbers or simulate analog voltages. EasyEDA is the better pick for designing a board; digiwleea is the better pick for learning the logic that goes on it, and the chip pages here (7400, 74HC595 and more) show what common logic chips do inside before you place them in a schematic.

No sign-up is needed to start: open the lab and place your first transistor, or read the free theory course. The account (and the AI tutor) are optional.

See for yourself: build a logic gate from transistors in the simulator, then follow the path from sand to an 8-bit CPU.

Frequently asked

Is digiwleea a good EasyEDA alternative?

Yes, if you want to understand digital logic from the ground up. digiwleea is a free, in-browser simulator with a guided 40+ level course where you build every gate from CMOS transistors and work up to a real 8-bit CPU, with an AI tutor to help.

Is digiwleea free?

The sandbox lab and the first act of the course are free and need no sign-up. An optional account adds the AI tutor and cross-device sync; the full course and expanded AI tutoring are included in the monthly or annual Premium subscription.

Do I need to install anything?

No. digiwleea runs entirely in your browser, on desktop or mobile, and works offline once loaded.
