Plugin Check is an essential tool designed for WordPress developers to ensure their plugins meet the stringent standards required by the WordPress.org plugin directory. This free plugin allows users to run comprehensive checks that cover various aspects of plugin development, including internationalization, accessibility, performance, and security best practices. With an intuitive user interface available in the WP Admin, developers can easily navigate to the Tools > Plugin Check menu to initiate tests on their plugins.

In addition to the WP Admin interface, Plugin Check supports command-line operations through WP-CLI, offering flexibility for advanced users. Users can perform static and runtime checks by employing specific commands, ensuring thorough testing before submission. While Plugin Check is not a substitute for manual reviews, it serves as a valuable resource for streamlining the approval process and minimizing common development errors, making it a recommended tool for both new and experienced WordPress developers.
