Frequently asked questions

Quick answers about how GyverNet works.

GyverNet does not show prices - we show verified specifications, location and real supplier reputation. Prices vary by volume and contract; contact is always direct between you and the supplier, with no middlemen and no favouritism.

Yes, searching and comparing specs is always free — no account needed. We plan to monetize later through optional supplier tools, never by charging engineers.

Every submitted catalog is manually reviewed before publication. Suppliers get a "Verified" badge once their company details and specifications are confirmed.

TraceParts hosts CAD models published by individual manufacturers. GyverNet is a neutral comparison across multiple independent suppliers for the same standard part, ranked by verified reputation and location — not by who paid the most.

It's free. Visit /sellers, create an account, and upload your catalog as a CSV — most suppliers are live within a few days after review.
