// ABOUT ELASTICSEARCH

Elasticsearch is an established distributed search and analytics engine (dual-licensed, with AGPL and Elastic License options) offering full-text search, aggregations and vector search, with Elastic Cloud as its managed commercial service.

When to consider Infinity Data

▸You want a lightweight, single-service vector search and analytics layer
▸You want to self-host and keep embeddings on your infrastructure
▸You prefer a simple Apache-2.0 licence with no dual-licensing considerations
▸You want HNSW indexing with cosine, Euclidean and dot-product metrics
▸You want analytics tables (filter, group-by, aggregate) alongside vectors

Infinity Data vs Elasticsearch — at a glance

// AN HONEST NOTE

Elasticsearch is a mature, massively-scalable engine with rich full-text search, aggregations and a huge ecosystem — and it is itself available under open licences. Infinity Data is a much lighter, newer alternative targeting focused vector + analytics workloads, not Elasticsearch-scale cluster deployments.

Elasticsearch alternative — FAQ

Is Infinity Data a full-text search engine like Elasticsearch?
No — Infinity Data focuses on vector similarity search plus analytics tables. For heavy full-text search workloads with complex relevance tuning, Elasticsearch remains the stronger fit.
Is Infinity Data free?
Yes — open source under Apache-2.0 and free to self-host, with a single simple licence.
How mature is Infinity Data?
It is in active development. Benchmark recall, performance and scale against your workload before adopting for production retrieval.
