What this tool does

hreflang Validator gives you a fast, focused way to validate pasted locale and URL pairs for duplicate languages and malformed absolute URLs. Everything runs locally in this tab.

The result is produced only after the input is checked. If the value cannot be processed, the workspace reports a specific error instead of guessing.

Example

en-US | https://example.com/us/
en-GB | https://example.com/uk/
x-default | https://example.com/

Limitations
