Best Time-Series Databases 2026
Facts read 28 Sep 2026 – 15 Oct 2026
When your data is organized around time, database choices can hinge on how it arrives, how it is queried, and how long it stays available. Compare deployment and ingestion methods with query languages, horizontal scaling, retention policies, and SQL support. Free-plan availability and paid-from pricing offer further points of comparison. GreptimeDB, InfluxDB, and TimescaleDB lead the ordered entries, with QuestDB and TDengine also near the top. Consider your deployment approach, expected data flow, and querying needs, then weigh the listed scaling and retention capabilities against them.
