# Quasar (QuasarDB)

> QuasarDB is a distributed, high-performance time-series database from Bureau 14, built for the hardest data problems where precision, speed, scale, and accuracy must hold simultaneously. It combines live ingestion, lossless-compressed historical retention, and heavy analytics on a single distributed system, with deployments across aerospace & defense, finance, industrial operations, and scientific research. It exposes a REST API plus native client libraries in Python, Java, Go, .NET, C, PHP, R, Ruby, and (archived) Node.js.
