# Shippo vs EasyPost vs ShipStation: Shipping API Comparison 2026

## TL;DR

**EasyPost** is the best pure API for developer-built shipping workflows — clean REST API, multi-carrier rate shopping, and carrier-agnostic label generation. **Shippo** is the fastest path to shipping labels with a generous free tier (500 labels/month) and solid discounted carrier rates. **ShipStation** is an order management platform with an API bolted on, not an API-first product — the right choice for operations teams, not developers building custom shipping logic. For most e-commerce or marketplace platforms building shipping into their product, EasyPost or Shippo wins.

---

## Key Takeaways

- **EasyPost:** 100+ carriers; used by Shopify, Etsy, eBay; most developer-friendly API in the category
- **Shippo:** Free tier for 500 labels/month; pre-negotiated USPS/UPS/FedEx rates below retail; best for low-volume or startup use
- **ShipStation:** 40+ carriers; order management UI-first product; API is secondary; not recommended for programmatic-only integrations
- **Webhook support:** All three support shipment tracking webhooks; EasyPost has the most consistent event schema
- **Address validation:** EasyPost and Shippo include address validation APIs; ShipStation does not expose this separately

## EasyPost: The Developer Standard for Shipping APIs

EasyPost has been the go-to choice for developer teams building shipping into platforms since 2012. Its API design is RESTful, consistent, and well-documented — and its scale (powering Shopify's shipping infrastructure, among others) validates reliability at serious volume.

### Core API Flows

**Rate shopping:**
```bash
curl -X POST https://api.easypost.com/v2/shipments \
  -u "your_api_key:" \
  -d "shipment[to_address][street1]=417+Montgomery+St" \
  -d "shipment[to_address][city]=San+Francisco" \
  -d "shipment[to_address][state]=CA" \
  -d "shipment[to_address][zip]=94104" \
  -d "shipment[to_address][country]=US" \
  -d "shipment[from_address][street1]=2+Avenue+de+Lafayeffe" \
  -d "shipment[from_address][city]=New+York" \
  -d "shipment[from_address][state]=NY" \
  -d "shipment[from_address][zip]=10013" \
  -d "shipment[from_address][country]=US" \
  -d "shipment[parcel][length]=20.2" \
  -d "shipment[parcel][width]=10.9" \
  -d "shipment[parcel][height]=5" \
  -d "shipment[parcel][weight]=65.9"
```

Returns rates from all enabled carriers simultaneously, sortable by cost, delivery time, or carrier.

**Address verification:**
```bash
curl -X POST https://api.easypost.com/v2/addresses \
  -u "your_api_key:" \
  -d "address[verify][]=delivery" \
  -d "address[street1]=118+2+Avenue" \
  -d "address[zip]=10003" \
  -d "address[country]=US"
```

EasyPost's address verification is USPS CASS-certified — the API corrects malformed addresses and flags undeliverable ones before you create a label.

### EasyPost Pricing (2026)

EasyPost is **pay-per-label** with no subscription fees at lower volumes:

| Volume | Label fee |
|---|---|
| USPS (all tiers) | $0.05/label |
| UPS/FedEx | $0.05/label |
| Volume discounts | Negotiate at 10K+/month |

Pre-negotiated carrier discounts apply on top of label fees. USPS Commercial Base rates (up to 37% below retail) are available to all EasyPost users from day one.

### EasyPost Limits

- No built-in UI — you build everything yourself
- Customer support is email-based at lower tiers; live support requires Enterprise contract
- International carrier coverage is strong but requires per-carrier setup

---

## Shippo: Best Free Tier and Fastest Start

Shippo targets e-commerce businesses that want discounted rates and simple label generation without building a full shipping abstraction layer. Its developer API is well-designed, and the free tier is genuinely useful for low-volume use.

### Shippo Free Tier

Shippo's **starter plan** gives you:
- 500 labels/month at Shippo discounted rates
- USPS, UPS, DHL Express rates included
- Access to the full API and tracking webhooks
- No credit card required

This makes Shippo the best choice for hackathons, MVPs, and early-stage e-commerce products that don't have the volume to justify per-label EasyPost fees.

### Shippo Discounted Rates (2026)

| Carrier | Shippo discount vs retail |
|---|---|
| USPS Priority Mail | Up to 82% off |
| UPS Ground | Up to 77% off |
| DHL Express Worldwide | Up to 77% off |
| FedEx Ground | Up to 75% off |

Shippo's pre-negotiated rates are competitive with EasyPost's for USPS, and slightly better for DHL on small package volumes.

### Shippo Pricing Beyond Free Tier

| Plan | Monthly cost | What changes |
|---|---|---|
| Starter | $0 | 500 labels/month |
| Professional | $19/month | Unlimited labels, branded tracking |
| Premier | Custom | Dedicated support, custom rates |

The $19/month Professional plan removes the 500-label cap and adds branded tracking pages — worth it as soon as you're at 100+ shipments/month and care about post-purchase experience.

### Shippo API Example

```javascript
import Shippo from 'shippo';

const client = new Shippo({ apiKeyHeader: 'ShippoToken YOUR_KEY' });

const shipment = await client.shipments.create({
  addressFrom: {
    name: 'Shawn Ippotle',
    street1: '215 Clayton St.',
    city: 'San Francisco',
    state: 'CA',
    zip: '94117',
    country: 'US'
  },
  addressTo: {
    name: 'Recipient',
    street1: '965 Mission St.',
    city: 'San Francisco',
    state: 'CA',
    zip: '94105',
    country: 'US'
  },
  parcels: [{
    length: '5',
    width: '5',
    height: '5',
    distanceUnit: 'in',
    weight: '2',
    massUnit: 'lb'
  }],
  async: false
});
```

### Shippo Limits

- 40+ carriers (vs EasyPost's 100+) — international carrier gaps exist for Asia-Pacific
- No USPS address certification (EasyPost and USPS APIs have this, Shippo does not)
- Rate shopping is slightly less granular than EasyPost's response schema

---

## ShipStation: Order Management Platform, Not a Developer API

ShipStation is included here because developers encounter it in job requirements and e-commerce stack discussions, but it's architecturally different from EasyPost and Shippo. It's an **operations tool** with an API, not an API-first product.

### What ShipStation is good at

- **Order import from 100+ sales channels** (Shopify, Amazon, eBay, Etsy, WooCommerce)
- **Batch label printing** via UI
- **Carrier rate rules and automation** configured in-app
- **Team workflows** — pick, pack, ship with role-based access

### ShipStation's API limitations

The ShipStation API lets you create orders, mark them as shipped, and get tracking info — but the rate shopping and label creation flows are UI-driven, not API-driven. You can't programmatically select a carrier and purchase a label the same way you do in EasyPost or Shippo without significant workarounds.

### ShipStation Pricing (2026)

| Plan | Monthly | Shipments/month |
|---|---|---|
| Starter | $9.99 | 50 |
| Bronze | $29.99 | 500 |
| Silver | $59.99 | 1,500 |
| Gold | $99.99 | 3,000 |
| Platinum | $149.99 | 6,000 |
| Enterprise | Custom | 10,000+ |

## Use Case Decision Guide

| Use case | Best choice |
|---|---|
| Building shipping into your SaaS/marketplace | **EasyPost** |
| Early-stage e-commerce, low volume | **Shippo** (free tier) |
| Operations team managing manual shipments | **ShipStation** |
| 100+ carriers required | **EasyPost** |
| Best discounted USPS rates, low volume | **Shippo** |
| Need address validation API | **EasyPost** |
| Want branded tracking page | **Shippo Professional** |
| Enterprise custom carrier negotiation | **EasyPost Enterprise** |

---

## Cost at 1,000 Labels/Month (USPS Priority)

| Platform | Estimated monthly cost | Notes |
|---|---|---|
| EasyPost | ~$50 | $0.05/label fee + discounted carrier rate |
| Shippo Professional | ~$19 + carrier | $19/mo subscription, no per-label fee |
| ShipStation Bronze | ~$29.99 | Plus carrier rate — operations tool |

At 1,000 labels/month, Shippo Professional is the cheapest option. At 10,000+ labels/month, EasyPost's volume discounts and carrier breadth make it the better long-term choice.

---

## Which Shipping API Should You Use?

**Choose EasyPost** if you're building shipping functionality into a platform, marketplace, or SaaS product. The 100+ carrier network, address validation API, and test mode make it the most developer-complete solution.

**Choose Shippo** if you're early-stage, shipping under 500 labels/month, or want the fastest possible setup with pre-negotiated carrier discounts. The free tier is genuinely generous.

**Choose ShipStation** if your team manages shipping operations through a UI, imports orders from multiple sales channels, and doesn't need programmatic label creation.
