ShipEngine is a multi carrier shipping API designed for parcels and small packages. Warp is a freight API for palletized freight: LTL, truckload, box truck, and cargo van. If you are shipping boxes and envelopes, ShipEngine is built for that. If you are shipping pallets, crates, and full trucks, Warp is built for that.

Different APIs for different freight
ShipEngine and Warp are not competitors. They solve different problems. ShipEngine connects to FedEx, UPS, USPS, and DHL to give you parcel rates, label generation, and package tracking for e commerce. It is designed for boxes that fit on a conveyor belt.
Warp is freight infrastructure for everything that does not fit in a parcel box. Palletized LTL routed through cross dock facilities. Full truckload with dedicated 53 foot trailers. 26 foot box trucks with liftgate for mid size deliveries. Cargo vans for urgent, small freight that needs a dedicated vehicle.
The question is not which is better. The question is what you are shipping.

Using ShipEngine and Warp together
Many shippers use both. ShipEngine for parcel. Warp for freight. The two APIs are independent and handle different parts of your shipping program. Your system routes each order to the right API based on weight, dimensions, and delivery requirements.
Under 150 lbs and fits in a box? ShipEngine generates the parcel label. Over 150 lbs, palletized, or needs a dedicated vehicle? Warp quotes and books the freight. Both APIs return tracking data your system can display to customers.

Frequently asked questions
Yes. Many shippers use ShipEngine for their parcel volume (boxes and envelopes via FedEx, UPS, USPS) and Warp for their freight volume (pallets, crates, and full trucks). The two APIs handle different parts of your shipping program.
ShipEngine is designed for parcel shipping. It does not provide LTL rates, cross dock routing, box truck dispatch, or truckload capacity. If you are shipping palletized freight, you need a freight API like Warp.
Warp is built for freight: pallets, crates, and full trucks. For parcel labels and small package shipping, use a parcel API like ShipEngine. Warp does offer cargo van service for urgent small shipments that need dedicated vehicles.
It depends on your volume. If most of your shipping is small packages, start with ShipEngine. If most of your shipping is palletized freight, start with Warp. If you ship both, integrate both. The APIs are independent and do not conflict.
Parcel carriers charge dimensional weight pricing that gets expensive fast for heavy or bulky items. Warp freight rates are based on actual weight and dimensions with all inclusive pricing. For anything over 150 lbs or larger than parcel dimensions, freight is almost always cheaper.
ShipEngine for parcels. Warp for freight. Both in one stack.
When your shipments outgrow parcel carriers, Warp provides the freight infrastructure. LTL, FTL, box truck, cargo van. All inclusive pricing. One API call to quote, book, and track.
