About XBKit

What is XBKit?

XBKit is a free toolkit for cross-border e-commerce sellers. We build practical tools that help sellers on Amazon FBA, Etsy, Shopify, TikTok Shop, and B2B channels make better business decisions — faster, without juggling spreadsheets.

Who is it for?

XBKit is designed for independent sellers and small teams running international e-commerce businesses. Whether you're calculating FBA profit margins, figuring out Etsy fees, or converting currencies for a supplier quote, our tools give you answers in seconds.

Free forever

Core tools on XBKit are free with no login required. We believe sellers should be able to do quick calculations without signing up for yet another SaaS subscription. Some advanced features (batch processing, API access) may be offered as paid add-ons in the future — but the essential calculators will always be free.

Data and privacy

We don't store any data you enter into our calculators. All calculations happen in your browser. We use PostHog for anonymous analytics to understand which tools are most useful. See our Privacy Policy for details.
