About ReactiveSearch
ReactiveSearch is a free and open-source search stack that lets developers build and scale AI-powered search experiences. It provides a versatile set of tools to author search pipelines, build search UIs with low-code kits, and unify search and AI backends like Elasticsearch, OpenSearch, and OpenAI.
What problem does it solve?
ReactiveSearch addresses the complexity of building search from scratch. It eliminates the need to wire together disparate search and AI services, offering a composable workflow with JavaScript pipelines, 30+ pre-built UI components, and out-of-the-box analytics to improve relevance and conversion.
Who is it for?
It's ideal for developers and product teams at marketplaces, e-commerce, and content platforms that need to ship fast and iterate on search quality. It's not for teams looking for a fully managed, no-code-only solution without any development involvement.
Real use cases
Use ReactiveSearch to build faceted product search for e-commerce, implement typo-tolerant search for documentation, or create a unified search interface across multiple data sources. With Docker deployment, it can be self-hosted in minutes, and its open-source nature ensures no lock-in.
