Why OpenSpindle

Built for automotive buyers

Real quotes, not estimates

Your part is quoted by independent shops set up for automotive work, so the price reflects the real job, not an automated estimate that changes later.

No sales gate

Upload a drawing and request quotes without a sales rep or account manager in the middle. Faster than the login-walled portals.

Prototype and motorsport friendly

Independent shops routinely quote single prototypes, race one-offs, and small aftermarket batches, not just high-volume production runs.

Compare multiple shops

See several independent shops set up for automotive work and compare quotes rather than taking a single price.

Trust

Certifications and standards that matter

For automotive work, the right certification depends on where the part is going. OEM production has strict quality gates, while motorsport, aftermarket, and prototype work is often far less certification-gated. Confirm the specific scope for your part.

IATF 16949

The automotive quality management standard, built on ISO 9001 with additional requirements for production and service parts. The baseline expectation for OEM and tier-one production supply chains.

ISO 9001

The general quality management baseline. Common on shops that do automotive work outside OEM production, and often sufficient for aftermarket, motorsport, and prototype parts.

PPAP

Production Part Approval Process, the automotive workflow for demonstrating that a shop can consistently make a part to print before volume production. Required by most OEM and tier-one customers on new parts.

Motorsport & aftermarket work

Motorsport, aftermarket, and prototype parts are usually less certification-gated than OEM production. Here the priorities are turnaround, material selection, and a shop that can iterate on a design, so judge shops on capability and communication rather than a certificate.

Questions

Frequently asked questions

Yes. Many shops on OpenSpindle focus on motorsport, aftermarket, and restoration work, which is usually less certification-gated than OEM production. For these parts, judge a shop on capability, materials, and turnaround rather than a formal automotive certificate.
