About
GCode Compare is a focused macOS tool for comparing two G-code files side by side. Load `.gcode`, `.nc`, `.tap`, `.cnc`, or text files and quickly see unchanged, changed, inserted, and deleted lines.
Built for CNC, 3D printing, and CAM workflows, the app includes useful G-code-aware comparison options. You can ignore whitespace, comments, `N` line numbers, and letter case to focus on meaningful toolpath differences instead of formatting noise.
The comparison view includes line numbers, color-coded difference states, quick filtering, summary counts, and a plain-text report you can copy or export.
Features:
- Side-by-side G-code comparison
- Support for common G-code and text file extensions
- Ignore whitespace, comments, line numbers, and case
- Filter by changed, inserted, deleted, or unchanged rows
- Difference summary counts
- Copy or export a comparison report
GCode Compare keeps the workflow simple: choose two files, review the differences, and save the report when you need to share or archive the result.
