1Best for: Teams storing high-volume timestamped data who want to query it in plain SQL
Open sourceSelf-hostableSelf-hosted, Linux, macOS, Windows
Why switch from InfluxDB
Open-source time-series database that accepts InfluxDB line protocol but is queried in standard SQL.
Pros
- Apache 2.0 licence for the full single-node engine
- Standard SQL with time-series extensions instead of a custom query language
- Postgres wire protocol lets Grafana and Postgres drivers connect directly
- Takes InfluxDB-style line protocol, Kafka and Telegraf for ingestion
Cons
- Replication, high availability and access control need the paid Enterprise edition
- The open-source edition only has basic auth without encryption in transit
- Smaller ecosystem and fewer hosted options than InfluxDB or TimescaleDB

2Best for: Engineers running Kubernetes or microservices who want the de facto standard for metrics
Open sourceSelf-hostableSelf-hosted, Linux, macOS, Windows
Why switch from InfluxDB
Free, pull-based metrics store that is the default choice for monitoring Kubernetes and cloud-native services.
Pros
- Industry-standard metrics format supported almost everywhere
- PromQL is expressive for alerts and analysis
- Simple single-binary deployment
Cons
- No built-in long-term or clustered storage
- Metrics only, so logs and traces need other tools
- Basic UI, so you will want Grafana too

- Hourly billing with a 30-day trial
Cons
- No permanent free cloud tier
