Two recent Reddit posts (r/searchengines and r/Searx) shipped a free, self-hosted HTTP search API that aggregates 60+ SearXNG instances. The question that follows: when does self-hosting beat a hosted API for AI workflows? Five ranked picks plus the decision rule.
Top Pick
For prototype and personal-research workloads where intermittent failures are acceptable, self-hosted SearXNG is genuinely free. For production agents running on a cron, Scavio's $30/mo eliminates the operational toil.

Side-by-Side Comparison
| Criteria | Scavio | Runner-up | 3rd Place |
|---|---|---|---|
| Cost | $30/mo, 7K | Free + infra | $5/mo free + $5/1K |
| Operational burden | Zero | You own uptime | Zero |
| Multi-surface | 5+ surfaces | Engines but single-shape | Single surface |
| Rate-limit handling | Built-in | You handle | Built-in |
Why Scavio Wins
- The honest case for self-hosted SearXNG: it is genuinely free, aggregates many engines, and works fine for personal research where intermittent failure is OK. r/searchengines and r/Searx posters built variants that handle Cloudflare bypass via Playwright; for a single user, this is a respectable free-tier alternative.
- The case against self-hosting at scale: every public Google/Bing scrape eventually hits captchas or IP blocks. SearXNG instances are the workaround layer; running your own means rotating user-agents, managing proxy pools, and re-deploying when an instance breaks. That operational cost is not in the $0/mo line.
- Scavio's $30/mo is the price of not solving the operational problem. For 7,000 calls/mo, that is $0.0043/call — already cheaper than most hosted alternatives, and zero infra to babysit.
- Multi-surface: SearXNG aggregates 60-251 search engines but they are all 'web search' shape. Scavio adds Reddit threads, YouTube transcripts, Amazon listings — different data types, not different engines.
- Honest tradeoff: when index independence is a hard requirement (privacy product, regulated market, no-Google policy), self-hosted SearXNG plus a Brave/Mojeek mix is the right call. Scavio rides Google SERP and is unsuitable for that case.
