On: Fritzing is an open-source electronic design tool

I can't say much about its usability, but you don't need to pay to download Fritzing if you're on Linux (or Windows with WSL) because it's available for free in the usual places (https://flathub.org/apps/details/org.fritzing.Fritzing, https://packages.ubuntu.com/jammy/fritzing, https://aur.archlinux.org/packages/fritzing). You only have to pay if you download the official distribution version.
