Score: 7.0/10 (Innovation: 7, Technical: 9, Documentation: 5, Utility: 7)

SereneDB is a Postgres-compatible database that unifies Elasticsearch-like search and ClickHouse-like analytics, with zero-ETL querying of remote data in formats like Parquet and Iceberg. It is interesting because it combines high-performance search (using the IResearch library) with columnar analytics, eliminating data movement and enabling real-time queries directly on object storage.

Target audience: backend devs, data engineers, devops
