About ReactiveSearch
ReactiveSearch (formerly appbase.io) is an open-source search stack for building relevant, AI-powered search experiences on top of Elasticsearch, OpenSearch, Solr, and MongoDB. It pairs 30+ pre-built UI components for React, Vue, and React Native with composable search pipelines, a no-code UI builder, actionable analytics, and multi-layer access control. Once a commercial cloud service, the entire stack is now free and self-hostable via Docker.
