Elasticsearch is described as 'Unmatched relevance. Real-time insights. Anything is possible — when the precision of search meets the intelligence of AI' and is a popular Search Server in the development category. There are more than 50 alternatives to Elasticsearch for a variety of platforms, including Web-based, Linux, Self-Hosted, Mac and SaaS apps. The best Elasticsearch alternative is Algolia. It's not free, so if you're looking for a free alternative, you could try Algolia or Apache Solr. Other great apps like Elasticsearch are OpenSearch, Manticore search, Vespa and Searchspring.
