MockPL is a free Chrome extension designed for developers, testers, and QA professionals to streamline the process of filling out forms with Polish test data. It eliminates the need for manual data entry by automatically generating and populating fields with relevant information, including PESEL, NIP, REGON, IBAN, and more. With a simple click, users can fill an entire form at once, enhancing productivity and reducing errors associated with manual input.

The extension features three convenient methods for data entry: a popup option, right-click context menu, and smart autofill that intelligently detects field types based on labels. Privacy is prioritized, as all data is generated locally in the browser without any network requests or data collection. MockPL is an ideal solution for testing registration forms, admin panels, e-commerce applications, and any system requiring Polish identification data.
