Head-to-Head Comparison

SearXNG vs SerpAPI

SearXNG is a free, open-source meta-search engine you host yourself that aggregates results from 70+ search engines. SerpAPI is a managed SERP API that handles proxy rotation, CAPTCHA solving, and structured parsing for you. The decision comes down to how much ops time you can sink into maintaining scrapers versus how much you will pay for hosted infrastructure.

The verdict

SearXNG is the right call if you already have an ops team that can babysit scrapers and you value privacy above structured SERP features. For everyone else -- especially teams shipping agents into production -- the hours you save by not maintaining 70 engine adapters are worth more than the monthly API bill. SearXNG shines for internal search, not agent-facing workflows.

Consider Scavio instead

Scavio gives you structured Google, YouTube, Amazon, Walmart, and Reddit data in a single API at $30/mo for 7,000 credits. No proxy pool to maintain, no HTML parsing to write, and no AGPL license to worry about in your commercial product.
