GreptimeDB

GreptimeDB is a cloud-native time-series database for metrics, logs and events. It is developed by Greptime and licensed under Apache-2.0, an open-source licence. It supports OpenTelemetry, Prometheus and InfluxDB protocols, which lets it accept data from tools that already speak those formats, and it is also categorised under observability. It can be run self-managed, and the commercial GreptimeDB Enterprise is offered as a fully managed service or as a Bring Your Own Cloud deployment. The latest release is v1.2.1, dated 16 September 2026. The open-source software is free. The fully managed Enterprise edition is priced from $290 a month. Buyers who currently send metrics to Prometheus or InfluxDB can consider it as a destination that accepts the same protocols, which may reduce the work of changing their collection set-up, although they should test compatibility with their own tools. GreptimeDB suits teams that want to keep metrics, logs and events in one database rather than several, and that want a choice between running the software themselves and paying for a managed edition. The project shows as active, with a release in September 2026.
