GRX

GRX is a simple Gerber file viewer. The Gerber format is a vector format for printed circuit board (PCB) designs. GRX uses WebGL for rendering and WebWorkers for parsing using multiple cores.

GRX is a great way to check your Gerber files before production. GRX can display all layers of a PCB, including copper, solder mask, holes and text. GRX can also display a 3D view of your PCB.

GRX is open source software, so you can use it for free.

Here are some of the key features of GRX:

- Display all layers of the PCB

- Display a 3D view of the PCB

- Support for multiple cores

- Open source software
