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.

How FluentSnippets Works: Zero Database Queries Every other code snippets plugin keeps your code in the database and queries it on every single page load. FluentSnippets does not. Each snippet is stored as a real PHP file, with its title, description, snippet type and conditional logic recorded in a doc block at the top of that file. Those doc blocks are parsed once and cached into an index, so nothing is re-parsed on later requests. At runtime the plugin simply includes the files you activated, on the action hook you chose, exactly the way WordPress loads a plugin.

The result is zero database queries at runtime. Not “a few”. None at all. There is no snippets table to bloat your database, nothing for a SQL injection in some other plugin to reach, and no query for your host to slow down. It is a native, secure-by-design architecture, and it makes FluentSnippets the fastest code snippets plugin in its category.

Features

File-based Snippets: Your snippets are safely saved in your file system and load natively with zero database queries, so it’s safe, secure, and ultra-fast.

Custom Code Snippets: Write your custom code snippets including PHP, JS, CSS, HTML, and more. Categorize your snippets with groups, tags, etc

Advanced Conditional Logic: Execute code snippets solely under specified conditions like post type, date, URL, user type, and many more.

Automatic Error Handling: If a snippet ever triggers a fatal error, the error handler catches it, deactivates that one snippet, and tells you which line caused it, so a bad snippet never takes your site down.

Safe Mode Recovery: If custom code ever locks you out of wp-admin, a Safe Mode URL switches every snippet off so you can get back in and fix it. No FTP, no database surgery.

Export & Import: Move snippets between sites, or keep a portable backup of them, in a couple of clicks.

Block Editor Support: CSS snippets work inside the WordPress Block Editor (Gutenberg), so styling your site happens in a familiar place.

Custom Shortcode: With custom shortcode of your snippets, you can create custom dynamic content blocks and use them across your site and manage them.

Stand-alone Mode: The most interesting feature is the Stand-alone Mode. With this feature, you can add your snippets, activate the standalone mode, and then you can uninstall and delete the plugin and your snippets will still run via mu-plugins architecture and when you reactivate the plugin you can manage your snippets as before.

Dark Mode: A full dark theme across every screen, switchable from the admin bar and remembered between visits. The setting is shared with the other Fluent plugins, so switching it in one switches it in all of them.

Powerful Smart Conditional Logics We have added smart conditional logic to let you choose precisely where you want to execute your code. These conditional logics include

User’s Login State or Role

Type of Pages

Post Types

Taxonomy or Term-Based Rule

By Page / Post URL

Target Specific Page / Post / CPT

Date Based Conditions

FluentCRM Tag / Lists based rule of the current contact

Conditions are group-based: you can add several groups, each with its own set of rules, and the snippet runs whenever any one group matches.

Snippet Types FluentSnippets has four types of snippets. You can choose the snippet type from the snippet type selection.

Functions – PHP Snippet: This snippet is for all the PHP code that you need to execute in specific areas like you would write in your theme’s functions.php file.

You can use this snippet type to create functions/classes, hook into other actions and filters, and more.
