Code Engine is a snippets manager that doesn’t stop at snippets. Yes, it runs your PHP and JavaScript exactly where and when you want — frontend, backend, on a schedule, or inside your content. But its real magic is what happens after you write a function: the same little piece of code instantly becomes a tool your AI chatbots can call, a step you can drag into a visual workflow, and an endpoint the outside world can trigger. One function, three superpowers.
Most “code snippets” plugins stop at a textarea and a toggle. Code Engine treats your functions as first-class building blocks for the whole Meow Apps ecosystem — and for anything that can speak REST. Think out of the box, let your creativity flow, because the possibilities really are endless! ✨

<h3>Quick Intro</h3>
Hello! ☀️ I built Code Engine because I was tired of pasting mystery snippets into <code>functions.php</code> and praying. I wanted a place where small bits of code are organized, safe, AI-assisted — and reusable everywhere.
Here’s the idea. You write a function (or let the AI write it for you from a plain-English description). That function immediately shows up in three places:
<ul>
<li>AI Engine — your chatbots and MCP clients (Claude, ChatGPT, Claude Code) can call it as a tool, with real arguments. Ask “how many orders shipped today?” and your chatbot runs your function to answer.</li>
<li>Workflow Engine — your function appears in the step picker as its very own block. Drag it onto the canvas, wire it between an AI step and a Slack step, done. No glue code.</li>
<li>REST / External tools — give it a secure endpoint and a token, then trigger it from Make.com, n8n, Zapier, a cron job, or a webhook.</li>
</ul>
You never wrote an “integration.” You just wrote a function. Code Engine did the rest. 🤝
<h3>Core Modules</h3>
🧩 Snippets Manager 
Backend, Frontend, Persistent, Scheduled, Functions, and in-content (PHP/JS) snippets — all in one clean dashboard with tags, search, scope filters, and priorities.
🪄 AI-Assisted Coding 
Describe what you want in plain English and let AI Engine write the snippet — code, name, arguments, and scope included. Refine existing code or implement it straight from your comments.
🤖 Functions as AI Tools 
Every Function snippet becomes a function-calling tool and an MCP tool, so your AI Engine chatbots (and external AI agents) can actually do things on your site, not just talk.
🔀 Functions as Workflow Steps 
Workflow Engine surfaces each of your functions as its own draggable step. Your custom logic becomes a first-class citizen on the automation canvas.
🌐 External Access (REST) 
Expose any runnable snippet through a secured REST endpoint with a bearer token. Perfect for Make.com, n8n, webhooks, and scheduled external jobs.
🛡️ Safe Mode 
A snippet that throws a fatal error is automatically caught and disabled before it can take your site down. Code with confidence.
⏰ Scheduling 
Run a snippet daily at a chosen time via WP-Cron — reports, cleanups, syncs — without touching the server crontab.
🧱 Code Blocks & Shortcodes (Pro) 
Drop PHP or JS straight into a post or page with a Gutenberg block or the <code>[code-engine]</code> shortcode, with safety guards.
<h3>🧩 Snippets, the way they should be</h3>
Code Engine organizes your code by scope, so each snippet runs exactly where it belongs:
<ul>
<li>Persistent — runs everywhere (frontend + backend). Your everyday “add this to functions.php” code, but managed.</li>
<li>Frontend — runs only on the public site.</li>
<li>Backend — runs only in the admin.</li>
<li>Function — a named, callable function with typed arguments and defaults. This is the reusable building block (see below).</li>
<li>Scheduled — runs on a WP-Cron schedule, at the hour and minute you pick.</li>
<li>Content (PHP / JS) — runs inside a specific post or page, via a Gutenberg Code Block or the <code>[code-engine]</code> shortcode (Pro).</li>
</ul>
Everything is searchable, taggable, sortable by priority, and importable/exportable. The CodeMirror editor gives you proper syntax highlighting and keyboard shortcuts (<code>Cmd+S</code> to save, <code>Cmd+Enter</code> to run). A <code>nikic/php-parser</code> pass validates your PHP before it ever runs.
<h3>🪄 Let AI write it for you</h3>
Don’t feel like writing the boilerplate? Describe the snippet in plain language and Code Engine — powered by <a href="https://wordpress.org/plugins/ai-engine/" rel="ugc">AI Engine</a> — generates the whole thing: the code, a sensible name, a description, the right scope, and, for functions, the argument list with names, types, and defaults.
Already have code? Ask the AI to modify it from a prompt, or write a few comments describing what you want and let it fill in the implementation. It’s pair programming, right inside your dashboard.
<h3>✨ The big idea: write once, use everywhere</h3>
This is what makes Code Engine different. A Function snippet is not just code you call from other code — it’s a reusable capability that the rest of your stack can plug into. The moment you save it, the same function is available in three places at once:
1. As an AI tool — for chatbots and AI agents 
With <a href="https://wordpress.org/plugins/ai-engine/" rel="ugc">AI Engine</a> active, your functions are exposed through function calling and over MCP (Model Context Protocol). Your on-site chatbot can run them mid-conversation, and external AI agents — Claude, Claude Code, ChatGPT, OpenClaw — can call them too. Want a chatbot that checks stock, looks up a booking, or kicks off a process? Write the function; the chatbot gains the skill.
2. As a workflow step — for automation 
With <a href="https://meowapps.com/workflow-engine/" rel="nofollow ugc">Workflow Engine</a>, every active function shows up in the Add-step picker as its own block, named after your snippet, with one input per argument. Drag it onto the canvas and wire it between other steps — an AI step that summarizes, your function that saves, a Social Engine step that posts. There’s also a generic “Execute snippet (by ID / by name)” step when you want to call one dynamically. You never write integration code; your function is the integration.
3. As a REST endpoint — for the outside world 
Give a snippet a custom endpoint name and a bearer token, and it’s instantly callable from anywhere:
<pre><code>POST /wp-json/code-engine/v1/snippets-endpoint/your-endpoint
</code></pre>
Pass arguments as JSON in the body, secure it with a token, and trigger it from Make.com, n8n, Zapier, GitHub Actions, or a humble cron job. Automation without a middleware bill.
<h3>🛡️ Safe by default</h3>
Running arbitrary code is powerful, so Code Engine takes safety seriously:
<ul>
<li>Safe Mode catches fatal errors and auto-disables the offending snippet, so a typo never white-screens your site.</li>
<li>REST whitelisting means global snippets only run on trusted REST routes by default — you choose what to open up.</li>
<li>Per-snippet tokens secure your external endpoints.</li>
<li>Validation with a real PHP parser before code is saved.</li>
</ul>
For developers who want fewer guardrails, there’s a “Bypass REST Security” option and filters (<code>mwcode_rest_authorized</code>, <code>mwcode_rest_whitelist</code>) to tailor exactly what’s allowed.
<h3>Works beautifully with the Meow Apps family</h3>
Code Engine is one engine in a connected set — each one useful alone, magical together:
<ul>
<li><a href="https://wordpress.org/plugins/ai-engine/" rel="ugc">AI Engine</a> — chatbots, content generation, and MCP. Turns your functions into AI tools.</li>
<li><a href="https://meowapps.com/workflow-engine/" rel="nofollow ugc">Workflow Engine</a> — visual automation. Turns your functions into draggable steps.</li>
<li><a href="https://wordpress.org/plugins/seo-engine/" rel="ugc">SEO Engine</a> — smart, lightweight AI SEO.</li>
<li><a href="https://wordpress.org/plugins/social-engine/" rel="ugc">Social Engine</a> — schedule and automate social posts.</li>
</ul>

Supports: Gutenberg, Elementor, TinyMCE and shortcode
Display your code snippets in a stylish way inside your content. The plugin uses shortcodes and also very intuitive TinyMCE interface.
Starting with v2.0.3, the plugin offers support to be used via a custom Elementor Widget.
Starting with v2.0.1, the plugin offers support to be used via a custom Gutenberg block.
It will continue to support the default way of adding the code snippet via shotcodes.
Code Snippet DM was inspired by the <a href="https://carbon.now.sh" rel="nofollow ugc">Carbon</a> project. 
We created a simple way to display your code snippets but also have control over the way it appears, thus making it more stylish. 
Also, on the front end in the top right you will find a <code>Copy Code</code> button that allows you to copy to clipboard the entired code snippet.
The plugin provides you with a TinyMCE button that will allow you to display the code or an option to use a shortcode.
You can open the shorcode <code>[dm_code_snippet]</code> and in the content inside and close it <code>[/dm_code_snippet]</code>.
<h4>Elementor widget</h4>
The Widget is called “Code Snippet DM” and can be found on the Basic list of Elementor Widget after you activate the plugin. Keywords that can be used to find it: code, snippet, dm.
Once the widget is added in the Elementor editor, it can be customized via the sidebar settings that will appear for each widget. The sidebar will include all the settings that are available for the shortcode. Some of the settings will be applied in real time in your editor.
The code styling (syntax highlight) and line numbers are only available on the front-end, in the editor you will not be able to preview the correct colors for the code or the line numbers.
<h4>Gutenberg block</h4>
The block is called “Code Snippet DM” and can be found in the embed section of Gutenberg blocks. Keywords that can be used to find it: code, snippet, dm.
Once the block is added in the Gutenberg editor, it can be customized via the sidebar settings that will appear for each block. The sidebar will include all the settings that are available for the shortcode. Some of the settings will be applied in real time in your editor.
The code styling (syntax highlight) and line numbers are only available on the front-end, in the editor you will not be able to preview the correct colors for the code or the line numbers.
<h4>Shortcode Options</h4>
There are a number of options that you can use in the shortcode:
<ul>
<li>background with options yes or no will enable/disable the color background (Default yes)</li>
<li>background-mobile with options yes or no will enable/disable the color background for mobile devices (Default yes)</li>
<li>bg-color accepts any HEX, RGB or RGBA value to change the background color (Default #abb8c3)</li>
<li>theme with options light or dark that changes the code editor theme (Default dark)</li>
<li>slim with options yes or no that changes the code editor from default to a slim version, ideal for one-line code (Default no)</li>
<li>line-numbers with options yes or no that will enable a left side line number for columns (Default no)</li>
<li>language with options clike, css, javascript, markup, perl, php, python, ruby, sql, typescript, shell will highlight the syntaxes based on what you select for your code (Default php)</li>
<li>wrap with options yes or no will wrap the code or add a horizontal scroll bar to display it as it is (Default no)</li>
<li>height allows you to input any value and will set the code snippet height to that value. Example: 500px. (Default is empty)</li>
<li>copy-text this is used for the text shown on the copy button. If it’s not added it will use the default option. (Default Copy Code)</li>
<li>copy-confirmed this is used for the text shown after you click the copy button. If it’s not added it will use the default option. (Default Copied)</li>
</ul>
Example of shortcode:
<pre><code>[dm_code_snippet background="yes" background-mobile="yes" slim="no" line-numbers="no" bg-color="#abb8c3" theme="light" language="css" wrapped="no" height="500px" copy-text="Get the Code!" copy-confirmed="You have it!"]<pre>
.dm-code-snippet.dark {
 background: $default-bg;
 padding: 40px 35px 45px 35px;
 margin: 30px 0;
}</pre>
[/dm_code_snippet]
</code></pre>
Important: 
* If you use the shortcode directly, make sure to wrap the code in <code><pre></pre></code> as in the example above. 
* If you want to add HTML using the shortcode, you’ll need to escape the HTML before pasting it in the shortcode. (You can easily find an escape tool online to convert the code) 
* If you have code (not HTML) that uses ‘</’ and you add it with the shortcode and not the and the TinyMCE button, you will need to escape ‘</’ from your code in order to properly display it.
Use the TinyMCE button if you don’t want to add the shortcode yourself. (see Screenshots)
