SereneDB

SereneDB is a real-time search analytics database from a Berlin company of the same name, founded in 2025 by Alexander Malandin, Andrey Abramov and Valery Mironov. Its first production-ready release, named Krummelanke, was published on 22 September 2026. The pitch is consolidation: full-text, vector and hybrid search alongside SQL analytics over columnar storage, behind a PostgreSQL-compatible front end, so a team does not run a search cluster beside an analytical warehouse and keep the two in step. The search core is IResearch, a C++ information-retrieval library that members of the team have worked on since 2016, and the company says it outperformed two established search libraries on one of their own public benchmarks — that is the vendor’s own reading of a third-party benchmark, and it is not recorded as a score here. The complete single-node version is under the Apache 2.0 licence and published on a public code host; the company states that the single-node build always will be. What the announcement does not publish is a price list for anything beyond that, so a team sizing a cluster has to ask. For a buyer the interesting question is not the benchmark but the operational one: a single engine means one backup story, one access-control model and one upgrade path, and it also means one thing to be wrong about.
