Free PCB design software
Runs in the browser. No install, no licence key, no seat count.
Open the editor →What free actually means here
No install, no licence server, no per-seat cost to open a board. You design in the browser and export Gerbers, drill files and a BOM you can hand to any fab.
Against the desktop tools
KiCad is free and excellent, but it is a desktop install with a real learning curve. Altium is neither free nor cheap. PCBEditor sits where you want a board today without setting up a toolchain first.
Export is not paywalled
Gerber X2, Excellon drill, CPL and BOM. A design you cannot get out of a tool is not a design you own.
