Visit ReactiveSearch

ReactiveSearch is an open-source search stack for adding AI capabilities to site search incrementally. It combines search pipelines, UI components, relevance controls, analytics and access management in a single platform, with connectors for Elasticsearch, OpenSearch, OpenAI and HTTP-based APIs.

Core capabilities include ReactiveSearch Pipelines for building suggestions, faceted search, geo search, recommendations and personalized feeds with JavaScript or YAML/JSON definitions, plus AI Answers for natural language queries with caching and curation. The platform offers UI components for React, Vue, Flutter and React Native, a dashboard control plane for tuning relevance, synonyms, aggregations, query rules and index settings, and analytics covering searches, filters, CTR and conversions. Access controls include API credentials, role-based access, field-level filtering and JWT/Basic Auth.

It is aimed at developers and business teams building search experiences, with marketplace-specific tooling for merchandising and product discovery. The software is free and open-source, self-hostable via Docker, with community support through GitHub and enterprise support available on request. An early-stage startup program offers discounted access to the full suite of tools for eligible companies.
