Code Engine – PHP Snippets, AI Functions & Automation for WordPress vs OpenStation

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! ✨ For more, check the official website and come say hi on the Discord. Quick Intro Hello! ☀️ I built Code Engine because I was tired of pasting mystery snippets into functions.php 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: 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. 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. 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. You never wrote an “integration.” You just wrote a function. Code Engine did the rest. 🤝 Core Modules 🧩 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-engine] shortcode, with safety guards. 🧩 Snippets, the way they should be Code Engine organizes your code by scope, so each snippet runs exactly where it belongs: Persistent: runs everywhere (frontend and backend). Your everyday “add this to functions.php” code, but managed. Frontend: runs only on the public site. Backend: runs only in the admin. Function: a named, callable function with typed arguments and defaults. This is the reusable building block (see below). Scheduled: runs on a WP-Cron schedule, at the hour and minute you pick. Content (PHP / JS): runs inside a specific post or page, via a Gutenberg Code Block or the [code-engine] shortcode (Pro). Everything is searchable, taggable, sortable by priority, and importable/exportable. The CodeMirror editor gives you proper syntax highlighting and keyboard shortcuts (Cmd+S to save, Cmd+Enter to run). A nikic/php-parser pass validates your PHP before it ever runs. 🪄 Let AI write it for you Don’t feel like writing the boilerplate? Describe the snippet in plain language and Code Engine, powered by AI Engine, 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. ✨ The big idea: write once, use everywhere 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 AI Engine 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 Workflow Engine, 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: POST /wp-json/code-engine/v1/snippets-endpoint/your-endpoint 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. 🛡️ Safe by default Running arbitrary code is powerful, so Code Engine takes safety seriously: Safe Mode catches fatal errors and auto-disables the offending snippet, so a typo never white-screens your site. REST whitelisting means global snippets only run on trusted REST routes by default, so you choose what to open up. Per-snippet tokens secure your external endpoints. Validation with a real PHP parser before code is saved. For developers who want fewer guardrails, there’s a “Bypass REST Security” option and filters (mwcode_rest_authorized, mwcode_rest_whitelist) to tailor exactly what’s allowed. Works beautifully with the Meow Apps family Code Engine is one engine in a connected set, each one useful alone, magical together: AI Engine: chatbots, content generation, and MCP. Turns your functions into AI tools. Workflow Engine: visual automation. Turns your functions into draggable steps. SEO Engine: smart, lightweight AI SEO. Social Engine: schedule and automate social posts. Why Code Engine? Reusable, not throwaway Other snippet plugins give you a place to paste code.

No clunky external dashboards, no bloat. AI-native Write snippets with AI, expose them to AI. The whole loop lives in your wp-admin. Developer friendly REST API, MCP tools, function calling, scheduling, import/export, and plenty of filters to hook into. Cared for Part of the Meow Apps family, with regular updates and a real human behind it. 💕

wp-admin forgets. OpenStation doesn’t. You know the moment. You’re deep in a post and you need one image from the Media Library. You click over, find it, click back, and everything you had going is gone. Your scroll position, your half-typed thought, the three other things you had queued up in your head. That’s not a bug you hit. That’s the design. wp-admin shows you one screen at a time, and every navigation throws the last one away. It has worked this way since 2003, like a fridge that empties itself every time you close the door. WordPress has rebuilt almost everything else. The editor, the site editor, the patterns, the styles. The admin’s one-screen-at-a-time model is the layer nobody touched. OpenStation touches it. Install it and admin screens become draggable, resizable windows. Edit a post while the Media Library sits open next to it. Drag an image from one window straight into the other. Keep comments open in the corner. Reload the browser and your window layout — open pages, positions, sizes, and window states — comes back where you left it. OpenStation itself is free, GPL, and opt-in per user. One click in the admin bar turns it on for you. One click turns it off. Nobody else on your site sees anything change, and deactivating the plugin restores the classic admin exactly. No Core patches and no lock-in. Optional AI providers may charge for their service. Built and maintained by Automattic, the company behind WordPress.com, Jetpack, WooCommerce, and Tumblr. Work on more than one thing at once Admin pages open as windows, including pages added by most other plugins. Drag them, resize them, snap them, tile them, minimize them to a taskbar. The admin menu becomes a dock of icons. Two editors open at once is one click away. Never lose your place Moving between open windows leaves each page in place. Across reloads, OpenStation remembers your open pages, window positions, sizes and states, virtual desktops, and focus. Closing a window with unsaved changes warns you first. A desk you can actually put things on Drop posts, media, and links right onto the wallpaper. Sort them into folders. Trash them to a Trash that actually holds things. The stuff you’re working on this week can just sit out where you can see it. One desktop per job Virtual desktops, the way your operating system does them. One for writing. One for the store. One for comment triage. One for that redesign you keep poking at. Switch between them without closing anything. Find anything with Cmd+K The full WordPress command palette, plus slash commands from your plugins, all under one keystroke. Turn on the optional AI assistant and you can ask it things like “which post had the comment asking for the recipe?” and it searches your own content to answer. (Requires an AI provider configured in Settings → Connectors on WordPress 7.0+. Details under “External services” below.) See how your site fits together The Corkboard is an interactive, zoomable map of how your posts, pages, and products link to each other. Pan around it. Find the orphans. Find the hubs. Running a store? Orders, Products, Coupons, and Customers become browsable folders with stock and sale ribbons. Open a customer to see their lifetime spend and what they buy most. Follow a product to its buyers, or a coupon to who redeemed it. Make it yours Wallpapers, from color presets to animated scenes to your own photo. Live widgets pinned to the desktop: drafts, stats, recent comments, a focus timer. Uploadable desktop themes, including a built-in Legacy theme that brings the old WordPress blue back in one click. And Mio, a soft-body desk companion that drifts across your wallpaper and gets bumped around by your windows. Off by default. You’ll turn it on. For developers Extend OpenStation through documented PHP and JavaScript APIs. Register windows, icons, wallpapers, widgets, commands, and settings tabs through stable openstation_register_* PHP APIs and a typed JavaScript API; customize dock items through documented hooks; add AI tools with the WordPress Abilities API. Copy-paste examples live in the developer docs on GitHub. External services No external service is required for OpenStation’s desktop interface. The optional AI Assistant and two user-initiated enrichment features make the external requests described below. AI Assistant The optional AI Assistant sends data to the AI provider you configure in WordPress’s Settings → Connectors (for example OpenAI, Anthropic, or Google). Generation is routed through WordPress 7.0’s built-in AI Client, which supplies the credentials stored in Connectors. The plugin never handles an API key itself. With no provider configured in Connectors, no external AI requests are made. When the AI Assistant is enabled and a user invokes it (via Cmd+K or the slash-command palette): What is sent: the user’s prompt, the conversation history for the active session, and tool-call metadata. The plugin’s built-in tools (search_posts, search_pages, search_comments) run WordPress’s native keyword search and may include excerpts of the matching posts/pages/comments in tool results, which are then sent back to the provider as part of the agentic loop. When it is sent: on user-initiated AI requests, and (if an administrator enables “Score new comments with AI”) on comment-save hooks for spam analysis. Posts, pages, and taxonomy terms are not sent automatically. Why it is sent: to obtain model completions and tool-call decisions that drive the AI Assistant. Who provides the service: whichever provider you configured in Settings → Connectors. Which provider (and endpoint) receives the data depends entirely on that configuration. Review the chosen provider’s own terms and privacy policy (e.g. OpenAI, Anthropic, or Google). URL shortcut favicons When an authorized user creates a desktop shortcut to an external URL, OpenStation asks that URL for its page HTML and favicon so the shortcut can display the site’s icon. The request is made from your WordPress server and sends the requested URL, the server’s IP address, an OpenStation user-agent string, and normal HTTP request metadata to the operator of that site. This happens only when a user creates the shortcut. The destination site’s terms and privacy policy apply. WordPress.org plugin information When an authorized user opens or refreshes parts of OpenStation’s Plugins window, OpenStation may request public plugin details, update metadata, and review excerpts from WordPress.org. These requests send plugin slugs, the site’s locale, and normal HTTP request metadata to WordPress.org. This information is used only to display and manage plugins. Review the WordPress.org Privacy Policy. OpenStation’s OAuth relay does not contact a service by itself. Third-party plugins that configure the relay may contact their own providers and are responsible for disclosing those services. Credits OpenStation is brought to you by Automattic. The plugin is open source under GPLv2-or-later; contributions are welcome on GitHub. Third-party libraries The plugin bundles the following third-party JavaScript library, loaded on demand only when a feature that needs it is in use: PixiJS (MIT License) — used by the Corkboard window, built-in canvas wallpapers (e.g. the animated WordPress logo), the Mio desk companion, and the Inkfall typing game. PixiJS is loaded from the plugin’s own assets/vendor/ directory; no CDN requests are made.
