Going-global tools for independent developers
Free tools for independent developers and global products, covering domains, email, VAT, payment fees, international pricing, UTM, localization and privacy policies.
What can you do with these tools?
This collection follows the practical workflow of launching a product internationally: inspect domains, DNS and email authentication; estimate Stripe fees and VAT; plan international pricing; build UTM links and social metadata; and check hreflang, localization and deployment configuration. Pages that query live DNS, email or network data identify the request destination. Tax rates and platform rules change, so verify official sources before making formal decisions.

Frequently asked questions
Which going-global tools require a network connection?
DNS, email-authentication and other live network checks require a connection. Form generators, UTM builders, pricing planners and some configuration tools generally process in the browser. Each page states its data handling.
Can VAT and payment-fee results be used directly for filing?
No. They are estimates and standard-rate references and do not cover every exemption, local rule or merchant contract. Verify tax-authority and payment-provider information before filing, invoicing or final pricing.
How should I choose tools for a global launch?
Use them in workflow order: check domains, deployment and email authentication; review localization and hreflang; estimate tax and international pricing; then build UTM and social-sharing metadata.
