Velxio is definitely inspired by Wokwi, and I really like what they’ve built. Parts of Velxio also reuse open-source components , for example, the wokwi elements are used for the visual SVG rendering of boards and peripherals, but they don’t include any emulation logic.

I also integrated a couple of existing open-source emulators, like the Raspberry Pi Pico and Arduino ones. And I even reached out to the creator of Wokwi to share the project.

In terms of differences, one of the biggest ones is that Velxio supports multiple heterogeneous boards in the same circuit: for example, two Arduinos connected over SPI or serial, ESP32 with Arduino, Raspberry Pi 3 with a Pico, etc.

Another major difference is the focus on full emulation, including ESP32 (via QEMU) and a Raspberry Pi 3 running Linux (still in beta).

There are also quite a few other differences, but those are probably the most notable ones
