Header Footer Code Manager (HFCM) is a simple and effective tool that allows you to add snippets to your head, footer, or any part of your WordPress website without making any edits to your theme or fussing around with code. Nowadays, there are various code snippets provided by services to ensure they work properly and are able to track, measure, or report on data. Rather than inadvertently take down your site due to misplaced code snippets, Header Footer Code Manager does the work brilliantly without editing your theme code.

Effortlessly add tracking codes, pixels or other scripts required for monitoring, analytics, marketing or simply adding a new feature (like a Live Chat app) to your website.

Common problems faced by users
Here are a few common problems faced by users while adding scripts / code to their theme:

Losing the code – One of the main issues faced by manually adding snippets to the theme is that the code added is lost every time the theme is updated, which might cause temporary loss of analytics or functionality provided by the script until it is replaced. HFCM adds these scripts using WordPress Hooks that are independent of the theme codebase so you can update your theme without affecting the scripts that are loaded.
Multiple plugins with the same basic functionality – A number of plugins are used just to add different types of scripts, which increases the load on the server and adds additional risk of plugin conflicts. HFCM supports all script types and can insert them where you need.
Managing a large number of scripts – If the site uses a number of scripts, it becomes very difficult to manually keep a track of them. Using a snippet code manager helps keep them organized and makes it easier to remember what scripts are for a specific purpose.
Targeting specific posts, pages, taxonomies or archives – Many times, when the script needs to be added to a specific page, it is added to the main header of the site, thereby decreasing the efficiency and adding unnecessary code to the rest of the site. HFCM allows targeting of specific elements for scripts as well as excluding the script from specific posts, pages, taxonomies, or archives.
