OpenSERP gives developers a totally free open-source SERP API they can run on their own infrastructure. Collect structured Google, Bing, Yandex, Baidu, DuckDuckGo and Ecosia results, then move the same search-data workflow to OpenSERP Cloud when you want a managed API.

The free, open-source SERP API for every major engine

OpenSERP handles browser automation, multi-engine parsing, and retry logic so you don't have to. MIT-licensed, production-ready, and a true open-source alternative to paid SERP API providers.

OpenSERP — common questions

Short answers to what developers ask before adopting a SERP API. See the docs for the long version.

Is OpenSERP really free?

Yes. OpenSERP is MIT-licensed open-source software. Self-host it with one Docker command and you pay nothing — no API keys, no per-query fees, no rate limits beyond what your own machine allows. OpenSERP Cloud is the optional managed version with pay-as-you-go pricing.

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

OpenSERP is the open-source alternative to paid SERP API providers. You get structured results for Google, Bing, Yandex, Baidu, DuckDuckGo, and Ecosia from one REST endpoint — without subscription fees or vendor lock-in. Use the OSS version free, or use OpenSERP Cloud when you'd rather not run the infrastructure.

Which search engines does the SERP API support?

Google, Bing, Yandex, Baidu, DuckDuckGo, and Ecosia — web and image search across all of them. 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?

Consistent JSON across every engine: titles, URLs, snippets, rank, and best-effort SERP features such as AI summaries, answer boxes, people-also-ask, and related searches. Same shape whether you self-host OSS or call OpenSERP Cloud.

Start with OSS. Scale with Cloud.

OpenSERP OSS is free and production-ready today. When you'd rather not run the infrastructure — Cloud is the managed path.
