Apache Druid
Real-time analytics database for sub-second OLAP queries
As of 13 November 2026, Apache Druid is free to use. Apache Druid is a high performance, real-time analytics database that delivers sub-second queries on streaming and batch data at scale. Softwr lists it under Databases. Apache Druid is made by Apache Software Foundation, launched in 1999, available on Self-hosted, API.
Overview
What Apache Druid does
Apache Druid is a high performance, real-time analytics database that delivers sub-second queries on streaming and batch data at scale. It is commonly used for powering use cases where real-time ingest, fast query performance, and high uptime are important.
What people use it for
- Real-time analytics platforms ingesting millions of events per second from streaming sources
- Applications requiring sub-second queries over high-cardinality datasets (billions to trillions of rows)
- Time-series and event analysis at massive scale with columnar storage efficiency
The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Apache Druid.
- Open-source offering lacks high-availability, distributed architecture, and enterprise security features
- Requires native integration with Apache Kafka or Amazon Kinesis for real-time ingestion; custom integrations need development
- High-concurrency query support (hundreds of thousands QPS) requires significant cluster infrastructure investment

Softwr does not host reviews and shows no star rating for Apache Druid, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
