Allow JSON, CSV and Other Data File Uploads
Lets administrators upload data files such as JSON, CSV, XML and Markdown to the Media Library, which WordPress blocks by default.
Snippet Library
Developer snippets for WordPress
Snippets for developers: debugging helpers, custom cron schedules, body classes, REST API tweaks and admin tools for checking hooks and queries. Building blocks for people who write code for WordPress every day.
Allow Random Order in REST API Post Lists
Lets REST API clients request posts with orderby=rand, for example to show a few random articles in an app, which WordPress does not allow by default.
Hide Update Notices for a Specific Plugin
Stops WordPress from offering updates for plugins you list, such as a customized plugin that must not be overwritten.
Limit REST API CORS to Your Own Apps
Replaces WordPress's permissive cross-origin (CORS) headers with an allow-list, so only the browser apps you name, such as a headless front end, can call the REST API with credentials.
Load a JavaScript Module Only Where It Is Needed
Registers a native JavaScript module with WordPress's Script Modules API and loads it only on pages that contain a chosen block, so modern ES module code needs no bundler and costs nothing elsewhere.
Log Every Redirect With Its Source
Writes each redirect WordPress makes to the error log, including the target, status code and the file that triggered it, to track down redirect loops.
Registered Image Sizes Under Tools
Adds a Tools > Image Sizes screen listing every image size WordPress creates on upload, with its width, height and crop mode, so you can see what themes and plugins have added.
Serve a humans.txt File
Answers /humans.txt with a plain-text file crediting the people and tools behind the site, generated by WordPress so you do not need to upload anything to the server.
Show Outgoing HTTP Requests in the Admin Bar
Counts the external HTTP requests WordPress, plugins and themes make while building a page, and lists each URL, status and time in an admin bar menu for administrators.
Show PHP Version, Memory and Queries in the Admin Footer
Replaces the WordPress version in the bottom right of admin screens with the PHP version, peak memory use and database query count of the current page.
Site Identity REST Endpoint for Apps and Headless Sites
Adds a public /wp-json/site/v1/identity endpoint with the site name, tagline, logo, site icon, language and home URL, so headless front ends and apps can brand themselves from WordPress.
Uptime Check Endpoint That Tests the Database
Adds a lightweight /wp-json/site/v1/ping endpoint for uptime monitors. It answers 200 only when WordPress can reach the database, and 503 otherwise, without exposing any versions.
