Who it suits
Makers who want a quick, private look at a Gerber ZIP and a rendered top and bottom of the board.
Cost
Free and open source (MIT licence).
Place by situation
With the design source: not listed (doesn't open source files) · Gerbers only: #3

Strengths

  • Files stay in your browser: its privacy policy says they are kept client-side and not sent anywhere. Usage tracking is opt-in.
  • Drop in Gerber and drill files, or a ZIP, and see a rendered top and bottom of the board as well as each layer.
  • Open source under the MIT licence; its libraries power other viewers too.

What it can't do

  • No design source files.
  • No measuring tool documented. Check in the app if you need one.
  • It guesses each file's layer from its name. Check every file landed on the right layer.
  • The code repository was last updated in January 2025, so fixes arrive slowly.

VerdictThe best private quick look: nothing leaves your browser, but don't expect measuring or source files.
