Everything a hardware team needs to track prototypes, and nothing it doesn't.
Proto Tracker replaces the prototype spreadsheet, the whiteboard and the 'who has board 7?' chat thread with one shared, permanent record.
Every unit, in one list you can trust
Serial, design, revision, status, location, mods and last change for every prototype you've built, filterable and sortable, with shareable URLs for every view.
- Batch-create units with automatic serial numbering (MC4-009 → MC4-033)
- Status summary chips show the state of the fleet at a glance
- Filter by design, revision, status, location or who has it; search serials, notes and custom fields
- Works on a phone at the bench as well as on a desktop
Each board's whole story on one page
Change status, location and holder inline. See how long it's been that way. Mark mods applied and remove them; each records who and when.
- Printable QR asset label (PNG) for label printers and tags
- Timeline of every change with before and after values
- Notes for test results, failure analysis and hand-over details
- Deleted prototypes keep their history
Model hardware the way it's actually developed
A design has revisions; revisions have mods: the bodge wires, component swaps and ECOs you apply to built units. Each mod shows how many units carry it and links to exactly which ones.
- Revisions named your way: A/B/C, 1.2, P1/P2, EVT/DVT/PVT
- Mods scoped to the revision they fix
- Moving a unit to a new revision is guarded while old-revision mods are applied
- Design-level history of renames and revision changes
Append-only, organisation-wide audit trail
Every create, update, move, status change, mod, invite and role change is recorded with who, what and when. It's written atomically with the change itself and can't be edited.
- Filter by record type, or by a single prototype or mod
- CSV export for audits, design reviews and customer reports
- Full JSON export of everything, any time
- Labels are kept, so history reads correctly after renames
The details that make it stick
Import your spreadsheet
Bring years of prototype tracking across in minutes. Columns are matched for you, every row is checked before anything is saved, and missing designs and revisions are created.
Custom fields
Firmware version, test rig, calibration date: add the fields your team tracks, with every change in the history. Business plan.
Who has it
Each unit can have a holder, so 'who has board 7?' has an answer. Click 'I have it' when you pick one up; every hand-over is recorded.
Two-factor authentication
Authenticator-app codes and recovery codes for every account, on every plan.
Organisations
Everything lives in an organisation. Invite colleagues by email; switch between organisations if you work with several teams or clients.
Roles
Owner, admin, editor and viewer. Viewers are read-only, which makes them ideal for managers, QA and customers, and extra read-only seats cost less.
One simple paid plan
Free for individuals. Business includes 5 people and every feature; add read/write or read-only seats as you grow. Manage it all yourself.
Light and dark
A soldermask-dark theme for the lab and a paper-light 'schematic' theme for the office. It follows your system setting.
Test log
Add timestamped log entries to any prototype: test results, observations, hand-overs. Like all history, they can't be edited afterwards.
Bulk updates
Select a batch and move it to the test house, or mark it passed, in one go. Every unit still gets its own history entry.
Install it anywhere
Add Proto Tracker to your phone's home screen or your desktop. It opens full-screen and starts fast, even on a flaky lab network.
Guided tour
New teammates get a two-minute interactive tour, with optional example data to explore. Run it again whenever you like.
Put every prototype on record.
Free for individual engineers. Business from $19 a month for 5 people, with a 1-month free trial.
