Our verdict on OpenSERP

OpenSERP is an open-source SERP API and command-line tool for developers, AI and research pipelines, SEO teams, agencies, and rank-monitoring workflows. It queries Google, Bing, Yandex, Baidu, DuckDuckGo, and Ecosia, returning structured results through REST and CLI interfaces. The product supports self-hosting with Docker or a Go binary, while OpenSERP Cloud provides a managed option.

The two plans suit different operating models. Self-hosted OSS is MIT-licensed, runs on your infrastructure, requires no API key, and covers six search engines. OpenSERP Cloud Pay-as-you-go costs $0.009 per credit, includes 60 starter credits, has no subscription, and lets credits remain available without expiration. One credit covers up to 10 returned web results. Cloud also adds managed API keys, usage history, extraction, Search Monitor scheduling, and AI-generated reports.

Its feature set extends beyond basic organic result retrieval. OpenSERP supports image search, URL and batch URL extraction, answer-box and related-search extraction, language, region, date, file-type, and site filters, plus HTTP and SOCKS5 proxy support. JavaScript/TypeScript and Python SDKs, an MCP server, and n8n integration support application and automation workflows. Choose OpenSERP when control over deployment, multi-engine collection, or structured pipeline access matters. Teams that do not want to operate their own infrastructure should use Cloud; teams seeking only a narrow single-purpose SERP endpoint may find this broader toolset unnecessary.
