digiwleea: a free Logic.ly alternative
Logic.ly is a polished logic simulator widely used in classrooms, with a clean drag-and-drop gate interface. 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 Logic.ly is good at
Logic.ly is a smooth, friendly way to wire up gate-level circuits, and many teachers like its simple interface.
How digiwleea is different
Two big differences: digiwleea is completely free with no install, and it teaches from a deeper layer. Rather than starting at pre-made gates, you build the gates themselves from transistors, then compose them into adders, latches, registers and finally a CPU, following a course with hints, checking, and an AI tutor. It is less a drawing tool and more a guided path to really understanding the machine.
| Logic.ly | digiwleea | |
|---|---|---|
| Price | Paid license | Free |
| Install | Download / paid web | In-browser, nothing to install |
| Smallest building block | Pre-built gates | CMOS transistors |
| Guided course to a CPU | No | Yes, 30+ levels |
| AI tutor | No | Yes (Wleea) |
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.

Is digiwleea a good Logic.ly alternative?
Yes, if you want to understand digital logic from the ground up. digiwleea is a free, in-browser simulator and 30+ 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 tutor are a one-time unlock plus an optional subscription.
Do I need to install anything?
No. digiwleea runs entirely in your browser, on desktop or mobile, and works offline once loaded.
