Drupal AI's SearXNG Pivot: Privacy or Just Performance Art?

The Drupal AI initiative has decided the next frontier for AI assistants is... self-hosting a meta-search engine. They're championing SearXNG as a "privacy-first" way for AI agents to search the web, which is a fantastically complicated way to solve a problem most of us don't have.

The Pitch vs. The Reality​

The problem, as framed by the initiative, is that having an AI assistant call out to a commercial search API is a privacy leak. Fair enough. When your Drupal site's agent queries Google for information, a little piece of your operational data is handed over.

The proposed solution is SearXNG. It's an open-source meta-search engine that you host yourself. When your agent needs to search, it queries your local SearXNG instance. SearXNG then queries Google, Bing, DuckDuckGo, and others on your behalf, aggregates the results, and returns them. Your server's IP is exposed, but the user's data isn't directly tied to the search. Privacy achieved, right?

Not so fast. What this actually means is you've just signed up to be the full-time administrator of a search engine.

The Glorious New Problems You've Created​

Let's be brutally honest about what adding this component to your stack entails.

  1. Operational Overhead: You now have another service to deploy, monitor, secure, and update. It's not a simple PHP library; it's a Python application with its own dependencies and failure modes. Who's on call when it breaks at 3 AM?
  2. Performance: You've replaced a highly optimized, globally distributed API endpoint with a single server (or a cluster, if you truly hate yourself) that has to make multiple outbound requests, parse the results, and aggregate them. It will be slower. There is no universe where this is faster than a direct API call.
  3. Getting Blocked: What do you think Google, Bing, and friends do when they see a single IP address firing off thousands of automated queries with a non-browser user-agent? They block it. You will spend a non-trivial amount of time managing proxy pools, rotating user-agents, and solving CAPTCHAs, all to scrape results you could have just gotten through a legitimate API.

This is a classic case of architectural overreach. It's a solution that looks great on a whiteboard but is a nightmare in production. It mistakes adding a complex moving part for adding value.

The Code​

No separate repo—this is an analysis of a proposed architecture, not a build. We have enough moving parts to deal with already.

What I Learned​

This whole exercise is a perfect reminder of a few core truths.

  • Self-hosting a complex service like a meta-search engine is a valid choice only if digital sovereignty is your absolute top priority and you have the operations team and budget of a small nation to back it up. For everyone else, it's a high-cost, low-reward distraction.
  • "Privacy" is not a feature you bolt on with a single component. If your stack is otherwise leaky, adding a "private" search tool is pure performance art for the benefit of no one.
  • Before adding any new service to your architecture, ask the painful question: "What is the total, long-term cost of owning this thing?" The maintenance cost is never zero, and it's often the thing that kills you.
  • For 99% of applications, the "privacy" gained by this Rube Goldberg machine is negligible compared to the massive operational burden. Just use a commercial search API and get on with solving problems that actually affect your users.
