You're not just choosing a shipping API. You're deciding what your engineering team will spend the next six months building.
The Real Question: Are You Buying an API or a Platform?
That question sits underneath every AfterShip API vs EasyPost API evaluation. On paper the two look similar: both expose clean RESTful endpoints, both cover multiple carriers, both fire webhooks. The decision that actually moves your roadmap is not the endpoint signature. It is what you have to build on top of the API yourself versus what ships ready to configure.
EasyPost is API-first, and that is a deliberate design choice, not a gap. It does sell user-facing pieces: Advanced Tracking adds branded tracking and notifications at $0.03 per shipment, and Embeddables provides pre-built UI components. The catch for most teams is access. Embeddables is gated to a Forge-enabled white-label account and aimed at platforms and marketplaces, not the standard merchant signup.
AfterShip runs the same idea in reverse. The Tracking, Shipping, and Returns APIs are the foundation, but a configurable branded tracking page and a full self-service returns portal come with the paid tiers. You still get headless control when you want it. That build-versus-configure choice has its own trade-offs, which we set out in build vs buy.
Quick Verdict: AfterShip vs. EasyPost for Developers in 2026
The Tracking API and webhooks are included from AfterShip's Premium plan ($59/month on annual billing, 6,000 shipments a year). Essentials covers the hosted tracking page without API access, and the Free plan includes no API access. EasyPost's tracking is included with any EasyPost shipment and sold standalone at $0.01–$0.03 per shipment.
Every figure on this page was read on 3 November 2026 from each vendor's own pricing page, product page or developer documentation, and each table cell names its source. We compared documentation, SDKs, webhook behaviour, rate limits, uptime commitments and published prices; we did not run load tests. AfterShip publishes this page, so the AfterShip rows are its own claims, each linked to the page it comes from.

Tracking and shipping are different scopes. AfterShip's 2,000+ Tracking carriers are read-only data integrations. AfterShip's 130+ Shipping carriers are where it generates labels and pulls live rates. Comparing AfterShip's 2,000+ Tracking figure to EasyPost's 100+ Shipping figure would be a category error, so each row is scoped explicitly.

What tracking costs at volume
| Shipments / year | AfterShip (Tracking API, Premium, annual billing) | EasyPost (standalone tracker, $0.01–$0.03) |
|---|---|---|
| 6,000 | $708/yr ($59/mo) | $60–$180/yr |
| 60,000 | $5,748/yr ($479/mo) | $600–$1,800/yr |
| 300,000 | $23,988/yr ($1,999/mo) | $3,000–$9,000/yr |
Read 3 November 2026. AfterShip list prices change on 17 November 2026.
Say it plainly: on the tracking line item alone, EasyPost is cheaper at every volume in that table. If all you need is a status feed, that is the right call and the rest of this article will not change your mind.
What AfterShip's number includes is the part a per-shipment comparison hides: a configurable branded tracking page with a custom domain and 52+ languages, notifications on every status change and revised delivery date, and AI delivery estimates — each of which is a frontend project on the other side.
Developer Experience: Docs, SDKs, and Support
- Documentation: AfterShip's API documentation is the canonical reference, with dated API versioning so a payload change never blindsides you in prod. EasyPost's documentation is similarly thorough. To make a first tracking call, start with the AfterShip Tracking API quick start.
- SDKs: a tie on coverage, seven official languages each.
- API design: both follow RESTful principles.
- Test environments: both provide test keys and a sandbox.
Here is the honest part. EasyPost's client libraries show stronger public GitHub adoption, roughly 700+ stars across its libraries, and EasyPost reports that more than 80% of its API requests come through them. AfterShip's tracking-sdk repositories sit at 0 to 2 stars each. On that one signal, EasyPost wins outright.
Read the signal for what it measures, though. GitHub stars track discoverability, not production usage. AfterShip's developer engagement shows up where people integrate rather than where they bookmark: its public Postman workspace carries 133 forks, 145 watchers, and 4 versioned collections. We applied the same hands-on lens across the market in which courier tracking providers developers actually rate highly.
Core Functionality: A Head-to-Head API Showdown
Labels and rates in the same integration
AfterShip Shipping covers 130+ label carriers and EasyPost covers 100+. Both numbers are label-and-rate scope, so that is a like-for-like count. The label-side endpoints are on the AfterShip multi-carrier shipping API page, and the first rates call is in the Shipping API quick start.
One API key is shared across AfterShip Tracking and Shipping, so a team adding labels later is not opening a second vendor relationship — though each product fires its own webhook, which is worth knowing when you design handlers.
Rate shopping is where the two design philosophies show. EasyPost's SmartRate is compact: one endpoint returns rates plus percentile transit-time predictions, at $0.03 per call after the first 500 free. AfterShip reaches the same outcome with a two-call pattern: the Shipping rates API for live rates, plus AI EDD for predicted transit. It is one more call. The trade is that the EDD model you query is the same one that later drives the estimates on your tracking page and notifications.
The per-label entry point favours EasyPost, and it is worth saying without hedging. AfterShip's Shipping API is gated to the Shipping Pro tier at $69 a month, while EasyPost's BYOCA plan starts at $20 a month plus a per-label fee, with free access up to 3,000 labels on wallet carriers. If the whole requirement is generating a label through an API call, EasyPost's raw-API entry is the lower-cost path and the right call. If labels are the whole job, we weigh AfterShip Shipping as an EasyPost alternative on its own.
Shipment tracking
The decisive difference is webhook reliability, the part of tracking that quietly breaks in production. AfterShip retries a failed webhook up to 14 times with exponential backoff (2^n × 30s), and every event carries an event<em>id (UUID v4) so your handler can dedupe replays safely. EasyPost retries 6 times within a 7-second response window and its payload carries a unique Event ID (evt</em>), with idempotency documented as something it encourages you to implement rather than a guarantee in the payload contract.
With AfterShip, idempotency is handed to you in the payload contract. With EasyPost, you use the Event ID as the basis for a dedupe key you design and store yourself. AfterShip's tracking payload is also richer: estimated delivery dates, geo-coded checkpoints, and multiple event types, instead of a status string you enrich yourself.
What the data looks like
Every tracking record names its carrier with a short slug, such as ups or fedex, and the supported couriers list gives the slug for each carrier AfterShip tracks. If a carrier's slug isn't obvious from its name, see how to find the slug for a carrier.
Status is normalized the same way. Rather than passing a carrier's own wording straight through, AfterShip maps every checkpoint to one of 7 main delivery statuses — InfoReceived, InTransit, OutForDelivery, AttemptFail, Delivered, AvailableForPickup, Exception — and then to one of 33 sub-statuses underneath it, such as InTransit<em>007 for a departure scan or Exception</em>004 for a customs delay. Both enums are versioned in the docs (delivery statuses, sub-statuses). For your code that means one switch statement instead of per-carrier string parsing, and a stable contract to hang notification and exception logic on as you add carriers.
The raw carrier message is carried alongside the normalised tag on the checkpoint object, so you keep the original wording if you need to display or debug it — confirm the exact field in the docs for the API version you pin.
Reliability and uptime
Reliability is a contract question, not a marketing one, so the two numbers belong in separate rows. Measured uptime: AfterShip publishes 99.99%+ and a live record on its status page; EasyPost publishes a status page without a headline figure. Contractual SLA: AfterShip commits to 99.9% monthly uptime with service credits in the Enterprise SLA; EasyPost publishes no SLA percentage publicly.
Rate limits matter the moment you scale. AfterShip publishes a 10 requests-per-second limit on Premium, with custom limits on Enterprise; EasyPost meters by plan tier. Know which limit governs the endpoint you are hammering before you design batching and retries. Throughput ceilings vary widely across the market, as the 2026 verdict on logistics tracking providers sets out.
On compliance, AfterShip carries SOC 2 Type II, ISO 27001, and GDPR, with the documentation collected in the Trust Centre.
Build your own carrier integrations or buy a tracking API?
| Build it yourself | Buy a tracking API | |
|---|---|---|
| Carriers you integrate | Every carrier on your lanes, then every new one | One integration covers 2,000+ |
| Status formats to normalise | One parser per carrier, re-tested when a format changes | 7 main statuses / 33 sub-statuses, versioned |
| Webhooks to maintain | Yours: delivery, retries, signing, dedupe | 14 retries with backoff, HMAC signing, event_id dedupe |
| Who fixes a carrier format change | Your team, usually during peak | The vendor |
| Customer-facing pages | Tracking page, returns portal, notifications — all yours to build and maintain | Configurable, included on the paid tiers |
| Cost line | Engineering time, indefinitely | $708–$23,988/yr depending on volume (table above) |
Where building wins: you ship on a handful of carriers, in one region, at very high volume, and you already run an in-house platform team that owns integrations. At that shape, per-shipment vendor pricing stops being the cheap option and a direct carrier integration pays back.
Where buying wins: every other shape — and especially the moment a customer-facing surface is in scope.
The bigger line item is returns. AfterShip's self-service returns portal is a complete customer-facing flow: select the item, choose a reason, pick a resolution, generate the label. Building that from scratch is a substantially larger project, because returns are not just a UI — they are state, policy, and label logic wired together. EasyPost sells real user-facing products, including Advanced Tracking and Embeddables, but it has no standard self-service returns portal, which means that entire build lands on your team.
The consolidation payoff is measurable. After moving its post-purchase stack onto AfterShip, Aetrex reported 50% lower operational costs, a 141-point NPS increase, an 86% reduction in return-processing time, and a 74% drop in WISMO tickets.
The integration tax is industry-wide, not a one-off. The MuleSoft 2026 Connectivity Benchmark found the average organization runs 957 applications with only 27% of them integrated.
Who runs it after launch
The build is only half the cost. On a raw API, the person running it every day is still an engineer. A Shopify merchant connects the store with a single click and AfterShip syncs shipment data into one dashboard. Carrier auto-detection identifies the right carrier from the tracking number, and from Essentials up, carrier auto-correction switches it automatically when a number gets paired with the wrong carrier. Notifications work the same way: an ops manager sets the trigger in the dashboard — email or SMS when a sub-status changes or the estimated delivery date shifts, from Essentials up — instead of writing handler logic for the same event stream.
The Honest Verdict: When Should You Choose EasyPost?
If you have a deep frontend team, you only need a label-generation engine, and you are committed to building and maintaining every customer-facing component yourself, EasyPost's focused, API-first approach is a clean fit. For a platform or marketplace that wants total control of the experience, that is a feature. If your shortlist runs wider than two names, we ranked which tracking provider holds up under production load.
Credibility cuts both ways, so here are two concerns a skeptical developer will find in AfterShip's own reviews. The first is Klaviyo setup friction: wiring up the native Klaviyo integration, available on Premium, takes more configuration than teams expect, because the work is mapping post-purchase events into Klaviyo flows. Start from the provided flow templates. The second is overage billing: AfterShip uses volume-based pricing and shipments past your quota bill incrementally, so size the volume slider to your peak month rather than your average.
Final Recommendation: Choose the API That Buys You Time
The best shipping API is not the one with the cleanest endpoint. It is the one that buys back the most engineering time. If your only requirement is to generate a label or read a status with a single API call, and you will never show a customer a tracking page or a returns flow, EasyPost is cheaper and simpler — the numbers above say so.
For any scaling eCommerce business, that view ignores the total cost of building and maintaining the full post-purchase experience. AfterShip's API-led platform removes that cost: your team spends its months on core product instead of rebuilding a tracking page and a returns portal that already exist, configurable, on the standard tiers.
Frequently Asked Questions
Which AfterShip plan includes the Tracking API?
Premium and above. The Tracking API and webhooks unlock on AfterShip Tracking Premium, which is $59 a month on annual billing for 6,000 shipments a year, with $0.12 per extra shipment and a published 10 requests-per-second rate limit. Essentials covers the hosted branded tracking page, notifications and carrier auto-correction but no API access, and the Free plan includes no API access. Enterprise is a custom quote based on annual shipment volume and scope, with custom rate limits. Prices read 3 November 2026; AfterShip list prices change on 17 November 2026.
How many carriers do AfterShip and EasyPost track?
AfterShip tracks 2,000+ carriers as of November 2026 — older AfterShip pages and third-party comparisons still quote 1,000+, so check the date on any figure you find. EasyPost tracks across 100+ shipping carriers, reusing the carrier integrations behind its label product and adding its Advanced Tracking layer on top. The two numbers measure different things and are worth separating: AfterShip's 130+ label carriers is the figure that compares like-for-like with EasyPost's 100+.
Is AfterShip more expensive than EasyPost?
On the tracking line item alone, yes, at every volume. EasyPost sells standalone trackers at $0.01–$0.03 per shipment, which works out at roughly $60–$180 a year at 6,000 shipments and $600–$1,800 at 60,000, against AfterShip Tracking Premium at $708 and $5,748 for the same volumes. The per-label entry point favours EasyPost too — BYOCA from $20 a month against AfterShip Shipping Pro at $69. What AfterShip's price includes is the branded tracking page, the notifications and the AI delivery estimates, each of which is a frontend project on the other side. The more user-facing surfaces you need, the more the math shifts.
What uptime do AfterShip and EasyPost guarantee?
Separate the measured number from the contractual one. AfterShip publishes 99.99%+ measured uptime with a live record on its status page, and commits contractually to 99.9% monthly uptime with service credits in the Enterprise SLA. EasyPost publishes a public status page for visibility but no SLA percentage publicly — if an uptime commitment has to survive a procurement review, that is the question to put to their sales team in writing.
Should I build my own carrier integrations instead?
Sometimes. Building wins when you ship on a handful of carriers, in one region, at very high volume, and you already run an in-house platform team that owns integrations — at that shape, per-shipment vendor pricing stops being the cheap option. Buying wins on every other shape, and decisively the moment a customer-facing surface is in scope. The costs to model are not just the first integration: one parser per carrier, re-tested whenever a carrier changes format, plus webhook delivery, retries, signing and dedupe, and whoever fixes it during peak season.
Can AfterShip create labels as well as track them?
Yes. AfterShip Shipping generates labels and pulls live rates across 130+ carriers through its own API, with Labels, Shipping rates, Cancel labels, End-of-day forms, Carrier accounts and US address validation endpoints, plus webhooks. One API key is shared across AfterShip Tracking and Shipping, though each product fires its own webhook. The label-side APIs are gated to the Shipping Pro tier. If labels are the whole requirement, EasyPost's entry price is lower and we say so above.
Is there a free tracking API?
Not from either vendor as an unlimited free tier. EasyPost includes a free tracker with every EasyPost shipment, so if you are already buying labels there, basic tracking costs nothing extra; standalone trackers are $0.01–$0.03 per shipment. AfterShip's Free plan covers 50 shipments a month with the hosted tracking page and carrier-based delivery estimates, but no API access — the API starts at Premium. For a prototype, EasyPost's free tracker on its own labels is the cheapest way to make a first call.
Can I use the AfterShip API without the pre-built pages?
Yes. The Tracking, Shipping and Returns APIs are usable headless, with plan tiering to account for: the Tracking API and webhooks from Premium, the Shipping API from Shipping Pro, and Returns webhooks and API from Premium. The pre-built tracking page and returns portal are optional accelerators, not prerequisites, so a team can adopt the API now and add the hosted UIs later without re-integrating — which is the part that usually decides it, since the alternative is building those surfaces and maintaining them yourself.
