A desktop app for EasyPost

Why a desktop app for EasyPost?

EasyPost gives you brilliant multi-carrier shipping, but out of the box you either write code against the API or work in the web dashboard. If you are a merchant, an operations person or a warehouse team, neither is what you want for printing labels all day. Easy-Post Desktop is a proper native application (Windows and macOS) that connects to your own EasyPost account and API key and gives you the whole workflow in a fast, focused interface.

It is a front-end, not a reseller: postage is billed by EasyPost directly, and the app never marks anything up or touches your money.

What the app does

• Rate shopping — compare live rates across USPS, FedEx, UPS and every carrier on your account, cheapest first.
• Labels — buy and print in PNG, PDF, ZPL or EPL, at the exact size your printer expects.
• Tracking — monitor parcels with automatic polling or optional real-time push updates.
• Address book & verification — country-aware fields covering 197 countries.
• Customs & HTS lookup — capture full customs data and search live U.S. tariff codes.
• Refunds, insurance, pickups, claims and batch CSV — the whole shipping lifecycle in one place.
• AI-agent access (MCP) — connect an assistant like Claude or Cursor to your shipping data to shop rates, with every purchase approved by you in the app.

Free to try, honest pricing

The app is free to install and runs fully in EasyPost test mode, so you can evaluate your entire workflow against your account before paying anything. A one-time $29.99 unlock enables production labels on your computer — no subscription, no timer. Teams needing multiple computers can license per seat on this site.

Private and open

Your API key is stored in the Windows Credential Manager and sent only to EasyPost's API. Shipping data stays on your machine — no analytics, no telemetry. The app is open source under the MIT licence, so nothing about how it touches your account is hidden.
