We list trade-offs explicitly. Browser-based + privacy-first means some features that need a server (cloud sync, named-account workflows) won't ship here.
RS-274X (extended Gerber) and Gerber X2 attributes. Excellon and XNC drill files are auto-detected. Older RS-274D (no embedded apertures) is not supported.
.zip, .tar, .tar.gz, and .tgz. Loose .gbr / .drl / .gtl / .gbl files are also accepted.
Not yet. Gerber RS-274X / X2 plus Excellon are the MVP. ODB++ and IPC-2581 are on the roadmap.
Distances are computed in the file's native coordinate system (typically millimeters at 0.1 µm resolution). Pad-center snap is geometric (centroid of the aperture flash).
