Posts about PCB review, diff workflows, and what we've learned building a local-first Gerber diff tool for production teams.
Personal has always been free, but it is a non-commercial license. If you are evaluating GerbDiff for work, there is now a 30-day Commercial trial. No card, no sales call.
Read the release notes →Save both revisions and everything about how you had them set up into a single .gdf, so a colleague opens it and sees exactly what you saw. Diffs are also about 2.5x faster, and academic use is now free.
Read the release notes →Most of the 3.1 line came from suggestions by Reddit user /u/FunDeckHermit: zip import, the command line, and now plain-text diff output and a project list that scrolls.
Read the release notes →The full app, every feature, no time limit. If you are working on your own projects, GerbDiff is yours to keep. Commercial use is licensed for professional work.
Read the announcement →Software engineering has used visual diff tools for production workflows since the 1990s. It's 2026 and hardware engineers still ship production PCBs to fab without this critical verification step. The average PCB respin in production is estimated to cost $28,000. Engineers make mistakes, but it's the release process that fails to catch those errors that is truly to blame.
Read the full post →We fixed a bug in the renderer that was causing certain objects to not draw properly during changes to zoom. They now render reliably at every zoom level.
Read the release notes →Driven directly by user feedback (Kudos to Dominique). When auto-alignment doesn't get your two revisions lined up, you can now type the offset instead of nudging the board across the screen one arrow-key press at a time. Plus support for more file extensions, including .gbx.
Read the release notes →A small follow-up to v2.8.0. Three targeted changes cut Summary Report generation time by roughly 4× on real boards. A report that previously took 35 seconds now finishes in 9.
Read the release notes →Two user-facing improvements to the Summary Report export, both driven by customer feedback this week. The save dialog now appears immediately when you click Export, generation runs behind a full progress overlay, and a single bad layer no longer aborts the whole report.
