Comparison based on publicly listed Pirate Ship features as of July 2026.
We are not going to pretend Pirate Ship is bad. It is a good tool, and for plenty of sellers it is the right call.
It is genuinely free
No monthly fee. For low volumes, that is tough to argue with.
The basics are covered
USPS and UPS labels, address verification, eBay syncing, and batch label buying from spreadsheets all work.
A large, established user base
It has been around for years and is a known quantity for sellers.
Once shipping stops being a few orders a week and starts eating your afternoons, the automation is what you are paying for.
One-click buy
Once an order has a weight and box, entered once or set by a rule, buy the label in a single click, with the address and cheapest service already filled in.
If/then automation rules
Set rules once, like "orders under 1 lb ship USPS Ground Advantage in a poly mailer", and flipfox applies them to every matching order. Pirate Ship has no rules engine.
Cheapest rate, picked out automatically
Pirate Ship shows you the rates and you pick. flipfox compares every carrier on your account per package and picks out the lowest rate, so you protect your margin without checking by hand.
Bring your own EasyPost account
flipfox buys labels through your own EasyPost account, so any rates you've negotiated come along. You're never locked into someone else's pricing.
If you ship a handful of orders a week and do not mind a few extra clicks per label, Pirate Ship is hard to beat on price. If you are shipping enough that syncing orders, comparing carriers, and buying labels by hand has become a daily tax on your time, flipfox pays for itself by handing that work to automation rules and one-click buying.
The Free plan needs no credit card, so the honest answer is to connect your eBay store and see how many clicks disappear.
Yes. Both let eBay sellers buy discounted USPS and UPS labels, but flipfox adds one-click buying, if/then automation rules, and the ability to connect your own EasyPost account. Pirate Ship is free and covers the basics; flipfox charges a monthly fee to automate the busywork around them.
Both give you discounted commercial USPS and UPS rates, so raw label costs are broadly similar, though the exact discounts differ by carrier and service. flipfox saves you money differently: it automatically compares every carrier on your EasyPost account for each package and picks out the cheapest rate, so you stop overpaying by defaulting to a single carrier.
If you ship a handful of orders a week, Pirate Ship is hard to beat on price. flipfox earns its fee once shipping becomes a chore: syncing eBay orders, buying labels in one click instead of a multi-step flow, and running rules that pick the box, carrier, and service for you.
Yes. flipfox buys labels through your own EasyPost account, which you connect once during setup. It comes with USPS and UPS, plus any negotiated rates already on your account. Your labels, tracking, and carrier accounts keep working the same way.
Yes. flipfox imports your eBay orders automatically and writes tracking back to eBay once a label is printed, so buyers get their tracking number without any copy-and-paste.
Connect your eBay store and print your first label in minutes.
