Software
Real-time analytics database for sub-second OLAP queries

- Free
- Rated
- -
The short version
- Only Apache Druid has a free tier, so it costs nothing to try first.
- Each has a real cost: Apache Druid open-source offering lacks high-availability, distributed architecture, and enterprise security features; Cloze four paid tiers run from $17 to $42 per user per month, and each withholds a different set of features rather than simply adding capacity
- They diverge on capability: Apache Druid covers Real-time Ingestion, Cloze covers Contact management.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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
Cloze
- Four paid tiers run from $17 to $42 per user per month, and each withholds a different set of features rather than simply adding capacity
- Campaign automation, marketing mail and generative AI require the Business Platinum plan at $42 per user per month
- Lead routing, sub team hierarchies and enterprise controls are Platinum only
- Even the Business Gold plan at $29 per user excludes the matching engine and lead capture
- The concierge service is an add on at $20 per user per month with a $500 monthly minimum
- Every published rate assumes annual billing
