Overview

OpenSERP is a SERP API that queries Google, Bing, Yandex, Baidu, DuckDuckGo and Ecosia and returns normalised JSON with titles, URLs, snippets, ranks and SERP features. The MIT-licensed server runs on your own infrastructure via Docker, or you can call the hosted API, which adds page extraction, API keys, usage history and scheduled rank and competitor monitoring with AI reports.

Best for: Developers and SEO teams needing programmatic multi-engine search data for AI grounding or rank tracking
Pricing: Self-hosting is free under an MIT licence; the hosted API is pay-as-you-go at $0.0090 per credit ($0.0078 effective with the +15% founder bonus, and as low as $0.0060 at volume), with 60 free credits topped up each month.
Runs on: Self-hostedCLI
