Check hardcoding and validation per area
Each locale-sensitive area is checked for whether it is hardcoded to one region's format and whether it validates input using region-aware rules.
Free MVP localization tool
LocaleFlow
Check whether your interface correctly handles regional differences in currency, dates, phone numbers, addresses, and names before you launch internationally.

Your inputs
Audit regional format handling
Enter one format area per line as Area | hardcoded to one locale (yes/no) | validated with regional rules (yes/no). List every locale-sensitive field or display in your product.

How it works
Flag the highest-risk hardcoded areas
Currency and address formatting are weighted as higher risk than cosmetic date display, since getting them wrong can actively break a transaction or delivery.
Score overall locale readiness
A combined score shows how much of your product is genuinely ready for a multi-region audience versus built assuming one locale.
Frequently asked questions
Is a single-locale MVP always wrong?
No — many MVPs correctly launch single-locale first. This tool helps you consciously choose that scope rather than discover locale assumptions baked in by accident later.
What is wrong with a first/last name field?
Many cultures do not use a first/last name structure — a single flexible "full name" field is often safer for an international audience unless you have a specific reason to split it.
Does this validate actual phone number formats?
No — you self-assess whether your validation logic is locale-aware; this does not run live validation against real phone number libraries.
How is this different from LocalizeUI?
LocalizeUI checks text length/translation layout risk; LocaleFlow checks data-format correctness (currency, dates, addresses, names) across regions.
