Unbloater is a simple and minimalist interface for cleaning up your WordPress admin dashboard and site code from unnecessary and not needed items. It mostly uses filters and actions to achieve fast and clean results. The settings screen is clean by itself, no additional styling or branding – that’s what the plugin stands for.
This plugin evolved out of my personal need to clean up sites for clients. The available options, especially for third party plugins, may therefore be biased. They might also be developer-focused in that the results work towards a cleaner site for non-technical users.
