Why OpenSERP

One API for every major search engine

OpenSERP handles browser automation, multi-engine parsing, and retry logic so you don't have to. MIT-licensed, production-ready, and built to be extended.

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, and engine-specific fields - same schema across all 5 engines.

Completely free

MIT-licensed with no API keys, no rate limits, and no vendor lock-in. Deploy on any infrastructure you already run.
