GerbDiff

Features

Everything you need to compare Gerber revisions

Compare two Gerber projects with synchronized pan and zoom. Switch between side-by-side and color-coded overlay views.

Pixel-level XOR diff mode instantly reveals every copper change, trace edit, and pad modification between revisions.

Detects and pairs layers across project revisions automatically. Supports copper, soldermask, silkscreen, drill, and more.

Clusters individual pixel differences into meaningful change regions. Navigate between them with N/P hotkeys.

Measure distances directly on the board in mils or millimeters. Click to place measurement points with live readout.

Generate PNG screenshots or self-contained HTML diff reports to share with your team or archive for review.

X1, X2, aperture macros, step-and-repeat, Excellon drill files. Handles real-world production Gerbers from any EDA tool.

All parsing, rendering, and diffing happens locally on your machine. Your Gerber files are never uploaded, transmitted, or stored externally.
