EasyPost vs ShipStation API (ShipEngine) (2026): which should you pick?

Pick EasyPost if

• Fits if you build your own checkout or app and need shipping labels from code
• Works for a shop that ships fewer than 3,000 labels and uses its carrier accounts

Look elsewhere if

• Not for you if you want a shipping dashboard with no code, as it is an API
• Watch out: the per-label fee after 3,000 free labels is not on the pricing page
• Pricey if you track a lot, as tracking costs $0.01 to $0.03 a shipment and Advanced Tracking $0.03
• Watch out: insurance costs 1% of shipment value, with a $1.00 minimum

Pick ShipStation API (ShipEngine) if

• Fits if you are a developer adding labels and tracking to a store or platform
• Works for teams that want discounted carrier rates with no monthly fee

Look elsewhere if

• Skip it if nobody on your team writes code
• Tight if you have your own carrier contracts, as those need Advanced at $75 a month
• Pricey if you grow: $325 at 5,000 labels and $600 at 10,000
• Watch out: ShipEngine's own site now redirects to ShipStation, and Enterprise is only for 25,000+ shipments a month through sales
