BOM History
Commit by Commit

See your entire BOM evolution through git commits. Track what changed, when it changed, and why — just like git blame, but for your bill of materials.

BOM History - Track component changes through git commits

BOM history available for 50+ open hardware projects:

HackRF One • BitaxeGT • OpenMower • xESC2

Full BOM history, automatically tracked

Every git commit becomes a BOM snapshot. Navigate your hardware evolution like you do with code.

Without BOM History With BOMblame
"When did we add this capacitor?" See exact commit, author, and commit message
"What changed between v2.0 and v2.1?" Select any two commits, see component diff instantly
"Why did the BOM cost increase?" Step through commits, see which parts were added/changed
Manual CSV exports for every version Automatic snapshots on every commit — zero manual work

Navigate BOM history like code history

Commit-by-Commit BOM Tracking

Every commit is automatically captured as a BOM snapshot. Browse your history, jump to any commit, and see exactly which components changed — with commit messages, authors, and timestamps.

Visual Diff Between Commits

Select any two commits and see a color-coded diff: green for added components, red for removed, blue for modified. Instantly understand what changed between hardware revisions.

Native EDA Parsing

We read KiCad, Altium, and Eagle files directly. No BOM exports. No column mapping. Just connect your repo and your history is ready.

Component Blame

See when each component was added, who added it, and why — just like git blame for your BOM.

Connect once. Track forever.
