Code Engine – PHP Snippets, AI Functions & Automation for WordPress vs SpamAnvil – AI Anti-Spam & Comment Spam Protection

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. Code Engine gives you a place to build capabilities that your AI, your workflows, and your external tools can all use. Native to WordPress Clean, fast, and built the WordPress way. 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. 💕

SpamAnvil is a free, open-source WordPress anti-spam plugin — and a genuine Akismet alternative — that uses artificial intelligence to block comment spam. Unlike Akismet (which requires a paid plan for commercial sites) or simple keyword-based filters, SpamAnvil leverages large language models (LLMs) to actually understand your comments and detect even the most sophisticated spam. It layers a honeypot, a time trap and per-IP rate limiting in front of the AI, so obvious bots are blocked for free. Traditional spam filters rely on static word lists and link counting. Spammers have evolved. SpamAnvil fights back with AI that understands context, intent, and language patterns – catching spam that looks legitimate and approving real comments that others would flag. Why SpamAnvil? Set up in about a minute – Activation opens a wizard that asks for one API key and verifies it before saving. Nothing is stored unless the test passes. 100% Free – No premium tier, no subscription, no hidden costs. Bring your own API key (free options available). Smarter Than Rules – AI understands context. A comment about “buying a new home” won’t be flagged just because it contains “buy”. Defense in Depth – Honeypot, time trap, per-IP rate limit and heuristics block obvious bots for free, so the AI is only spent on the subtle cases. Open Mode – Because the filtering is invisible and automatic, you can drop the usual barriers (name/email, login, moderation) and get more real comments – even anonymous ones – without opening the door to spam. Works With Free AI Models – Use OpenRouter’s free models for $0 cost, or connect premium models for maximum accuracy. Privacy-First – Your data stays between you and your chosen AI provider. IP addresses are stored as salted, keyed hashes (HMAC-SHA-256), not recoverable without your site’s secret. GDPR/LGPD compliant by design. No Cloud Lock-in – Choose from 6+ AI providers. Switch anytime. Your anti-spam, your rules. Supported AI Providers OpenAI (GPT-4o-mini, GPT-4o, etc.) Anthropic Claude (Claude Sonnet, Haiku, etc.) Google Gemini (Gemini 2.0 Flash, Pro, etc.) OpenRouter (100+ models, including FREE ones) Featherless.ai (Open-source models) Any OpenAI-compatible API (LM Studio, Ollama via proxy, vLLM, etc.) A Swiss-Army-Knife of Defenses SpamAnvil layers several spam defenses so cheap, invisible filters catch obvious bots for free and the AI only handles the subtle cases. Every layer is optional and runs before any paid API call: Honeypot – A hidden field bots fill but humans never see. Instant, free block. Time trap – Comments submitted faster than a human could type are flagged. Tamper-proof (signed) and fails open, so it never blocks a real visitor. Per-IP rate limit – Throttles comment floods from a single IP before they even reach the database. Heuristics engine – Regex/statistical pre-analysis (URLs, spam words, gambling/SEO author names, language mismatch, prompt-injection patterns) that auto-spams the obvious cases with no API call. AI verdict – An LLM scores the rest 0-100 in context. Key Features AI-Powered Spam Detection – Each comment is analyzed by an LLM that scores it 0-100 for spam probability. Works with reasoning models (their thinking is parsed correctly). Layered Bot Defense – Honeypot, time trap and per-IP rate limiting block obvious bots for free, before any AI call. Model Picker – Browse and search each provider’s live model list right from the settings page (OpenAI, OpenRouter, Featherless). OpenRouter shows a “free” badge and context size. “Open Mode” – One toggle removes WordPress comment friction (no required name/email, no login, no moderation hold) so leaving a real, even anonymous, comment is effortless. Comments appear instantly and spam is removed in the background. Verdict Cache – Identical repeated spam reuses a recent AI verdict instead of calling the API again, cutting cost during floods. Intelligent Heuristics Engine – Pre-analyzes comments to catch obvious spam without API calls. Async Background Processing – Comments are queued and processed via WP-Cron so your site stays fast. Smart IP Blocking – Automatically blocks repeat offenders with escalating ban durations (24h, 48h, 96h… capped at 30 days). Automatic Retry with Backoff – Failed API calls retry with exponential delays; a real “Test Connection” verifies actual classification, not just the HTTP status. Encrypted API Key Storage – Authenticated AES-256-GCM encryption, or wp-config.php constants for maximum security. Statistics Dashboard & Logs – Track spam caught by each layer, API usage and errors, with the AI’s reasoning for every comment. An admin warning surfaces silent failures (no provider, or a backlog of failed items). Customizable AI Prompts, Fallback Providers, Prompt-Injection Defense, Configurable Threshold, Moderator Bypass. How It Works A visitor submits a comment. Rate limit – too many comments from this IP too fast? Throttled with an HTTP 429 (before anything is stored). IP block – is the IP already banned for repeat spam? Blocked. Form traps – was the hidden honeypot filled, or the comment submitted implausibly fast? Marked as spam instantly, no API call. Heuristics – a quick regex/statistical pre-analysis; obvious spam is auto-marked with no API call. Otherwise the comment is queued for AI analysis (or processed immediately in sync mode). Identical repeated content reuses a cached verdict. The AI analyzes the comment in context (post title, author info, heuristic data) and returns a spam score. Comments above your threshold are marked spam; clean comments are auto-approved. Repeat-offender IPs are escalated. With Open Mode on, comments publish instantly and any spam is removed in the background instead of being held for moderation. Use Cases Blogs receiving hundreds of spam comments per day WooCommerce stores where comment spam affects SEO and credibility Membership sites that need to protect community discussions Multilingual sites – AI understands comments in any language, unlike keyword-based filters High-traffic sites – Async processing handles any volume without slowing down your site Sites tired of Akismet – Free alternative with no cloud dependency and full data control Security SpamAnvil follows WordPress security best practices throughout: Authenticated AES-256-GCM encrypted API key storage wp-config.php constant support for API keys (never touch the database) Configurable trusted IP header (default REMOTE_ADDR) so a forged X-Forwarded-For cannot bypass IP blocking or rate limiting Nonce verification on all forms and AJAX requests Capability checks on all admin actions Prepared SQL statements on every database query Output escaping on all rendered content Prompt injection defense: boundary tags around the comment body AND commenter metadata, system prompt hardening, heuristic injection detection (body and author fields), strict JSON validation, deterministic settings Languages English (default) Translation-ready (.pot file included) Third-Party Services SpamAnvil sends comment data (content, author name, email, and URL) to external AI services for spam analysis.
