Simple for Beginners, Powerful for Developers
Adding a snippet takes seconds: open the editor, paste or write your code, choose where it should run (everywhere, admin only, front-end only, or based on conditional logic), and save. A built-in syntax highlighter and smart error handling guide you along the way. If a snippet ever causes a fatal error, FluentSnippets automatically deactivates it so your site stays online instead of breaking. You can organize snippets with tags, switch them on or off with a single click, and export or import them between sites in seconds.
100% Free & Open Source: No Upsells, No “Pro” Version
FluentSnippets is completely free and fully open source under the GPL. There is no premium version, no locked or “Pro-only” features, no upsells, and no email-gated downloads. Every single feature is included for everyone, on every site, forever. The full source code lives on GitHub , so developers can read the code, audit it for security, request features, report bugs, or contribute directly via pull requests. It is built and actively maintained by the team behind FluentCRM, Fluent Forms, and FluentSMTP.
From Quick Tweaks to Advanced Customizations
From simple tweaks to advanced development, FluentSnippets handles it all. Use it to add Google Tag Manager and tracking pixels, register custom shortcodes, create custom functions, disable comments or emojis, remove unwanted admin notices, add JSON-LD schema markup, or run any PHP snippet you would normally drop into functions.php. CSS snippets even support the WordPress Block Editor (Gutenberg), so you can style your site with a familiar editing experience. Every snippet runs only where you tell it to, thanks to granular conditional logic based on post type, page URL, user role, login status, and more, so your custom code stays fast, targeted, and easy to manage.
