Check translated resources before testing the interface.

## Choose a check

Compare locale keys and placeholders with Locale File Checker. Generate expanded, accented resource strings with Pseudo-Localizer to expose clipping and hardcoded text. Supported files stay in your browser. Neither tool judges translation quality or replaces testing the rendered interface.
