OpenStation vs SpamAnvil – AI Anti-Spam & Comment Spam Protection

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. Data files The Inkfall game’s word list (assets/games/inkfall/words.txt) is generated from the following sources (attribution also ships in the file’s header): FrequencyWords by Hermit Dave (CC-BY-SA 4.0) — English word-frequency ranking derived from the OpenSubtitles corpus. english-words by dwyl (Unlicense) — used as a validity filter. LDNOOBW English list (CC-BY 4.0) — used as an exclusion filter.

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.
