Gatehouse
See what each plugin spends on AI, cap it, and see which plugins send personal data to AI providers. A free WordPress plugin.
- Cost per plugin: every AI call Gatehouse sees is traced to the plugin or theme that made it, with model, tokens, estimated cost, forecasts and a request log.
- Stop spending: monthly budgets (per plugin and site-wide), hourly call limits and a pause switch. Calls are stopped before they're sent.
- Alerts: for budgets, hourly limits and unusual activity.
- Personal data: shows which plugins send emails, phone numbers, card numbers, IBANs, US SSNs or your own terms to AI providers. Detection changes nothing; you can turn on redaction (placeholders out, real values back in the answer) per plugin. Pattern-based: it doesn't catch every name or address.
- AI data map: a CSV of which plugins send what to which providers.
What it can and can't see
- Sees: plugins that use the WordPress AI Client, and plugins that call Anthropic, OpenAI, Google, OpenRouter, xAI, Mistral, DeepSeek, Groq or Perplexity directly through WordPress's HTTP functions (for example AI Engine).
- Can't see: plugins that send AI requests to their own service (many SEO, page builder and form plugins), or that bypass WordPress's HTTP functions.
- Streamed answers read by the plugin itself are seen and can be blocked, but have no known cost.
