### REST API server

Start a local REST server with one Docker command. Query any engine from your app, script, or pipeline in seconds.

### Structured output

Consistent JSON with titles, URLs, snippets, ranks, and SERP features such as AI summaries, answer boxes, people-also-ask, and related searches.

### Free to self-host

MIT-licensed, with no API key or vendor lock-in. Run it on infrastructure you already operate. The hosted API is the paid path for teams that prefer not to.

## From solo developers to data-heavy teams

OpenSERP fits workflows that need reliable, programmatic search access: AI grounding, RAG, research, SEO rank tracking, competitor monitoring, and product data pipelines.

-   ### Developers & product teams
    
    Integrate live SERP data into apps, dashboards, or AI agents with a small REST API and minimal setup.
    
-   ### SEO teams & agencies
    
    Track rankings across Google, Yandex, Baidu, and Bing, monitor competitors, and inspect SERP features such as AI summaries, answer boxes, people-also-ask, and related searches.
    
-   ### Research & AI pipelines
    
    Ground LLM responses, RAG retrieval, and agent workflows on live, multi-engine search results, including Yandex and Baidu coverage.

Is OpenSERP really free?

The open-source version is, permanently. It is MIT licensed: self-host it and you pay nothing, with no API key, no per-query fee, and no rate limit beyond what your own machine allows. OpenSERP Cloud is the separate hosted product. Every new account starts with 60 free credits, and past that you pay per successful search with no subscription.

Is OpenSERP a free alternative to SerpApi, Serper, or Scale SERP?

The self-hosted version is a genuinely free alternative: structured results for Google, Bing, Yandex, Baidu, DuckDuckGo, and Ecosia from one REST endpoint, with no subscription and no vendor lock-in. You run the infrastructure. If you would rather not, OpenSERP Cloud is the hosted alternative and it is priced per successful search.

Which search engines does the SERP API support?

Google, Bing, Yandex, Baidu, DuckDuckGo, and Ecosia for web and image search. Cloud also exposes multi-engine megasearch endpoints that query several engines in one call.

How do I self-host OpenSERP?

Use the Docker image or Go binary to start a local REST server. Full installation commands and configuration details live in the docs.

Do I need an API key to use OpenSERP?

No key is needed for the open-source self-hosted version. OpenSERP Cloud uses bearer-token API keys (osk\_live\_…) so we can meter usage and bill credits per successful response.

What output format does OpenSERP return?

JSON by default, with Markdown, TXT, and NDJSON output options when you request them. The JSON shape stays consistent across engines: titles, URLs, snippets, rank, and best-effort SERP features such as AI summaries, answer boxes, people-also-ask, and related searches.
