The short version
- Only Apache Druid has a free tier, so it costs nothing to try first.
- Each has a real cost: PlanetScale eBS High Availability requires 3-node configuration with replication overhead; Apache Druid open-source offering lacks high-availability, distributed architecture, and enterprise security features
- They diverge on capability: PlanetScale covers Database Branching, Apache Druid covers Real-time Ingestion.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
PlanetScale
- EBS High Availability requires 3-node configuration with replication overhead
- EBS Non-HA single-node option lacks redundancy and automatic failover
- Pricing varies by cloud provider and region, requiring queries for specific rates
- ARM64 architecture only available on EBS tier, not Metal deployments
Apache Druid
- Open-source offering lacks high-availability, distributed architecture, and enterprise security features
- Requires native integration with Apache Kafka or Amazon Kinesis for real-time ingestion; custom integrations need development
- High-concurrency query support (hundreds of thousands QPS) requires significant cluster infrastructure investment

Questions people ask
- Is PlanetScale or Apache Druid better?
- Neither clearly leads. PlanetScale starts at $15/month and Apache Druid at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, PlanetScale or Apache Druid?
- Apache Druid has a free tier; the other does not. Paid plans start at $15/month for PlanetScale and Free for Apache Druid.
- Does PlanetScale or Apache Druid run on more platforms?
- PlanetScale runs on Cloud-hosted (AWS, GCP, Azure). Apache Druid runs on Docker, Kubernetes, Native deployment (Java-based).
- Can I use Apache Druid for free?
- Yes. Apache Druid has a free tier, so you can try it without paying. PlanetScale starts at $15/month.
- What is PlanetScale best used for?
- PlanetScale is most often used for mysql database hosting with automatic failover and replication, vitess-based sharding for horizontal scaling across large datasets, cloud provider flexibility across aws, gcp, azure with 60+ regions, cost-effective database clusters using arm64 architecture options. Of those, mysql database hosting with automatic failover and replication and vitess-based sharding for horizontal scaling across large datasets are not what Apache Druid is typically brought in for.
