PlanetScale vs CouchDB
The short version
- Only CouchDB 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; CouchDB append-only storage model may have performance implications for certain workloads with high update rates
- They diverge on capability: PlanetScale covers Database Branching, CouchDB covers Multi-master Replication.

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
CouchDB
- Append-only storage model may have performance implications for certain workloads with high update rates
- Requires network synchronisation for cluster data consistency; can introduce latency in multi-master scenarios
- No explicit support for complex joins; MapReduce queries may be inefficient compared to relational databases

Questions people ask
- Is PlanetScale or CouchDB better?
- Neither clearly leads. PlanetScale starts at $15/month and CouchDB at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, PlanetScale or CouchDB?
- CouchDB has a free tier; the other does not. Paid plans start at $15/month for PlanetScale and Free for CouchDB.
- Does PlanetScale or CouchDB run on more platforms?
- PlanetScale runs on Cloud-hosted (AWS, GCP, Azure). CouchDB runs on Docker, Windows (x64), macOS, Linux (Debian, Ubuntu, RHEL, CentOS), Raspberry Pi.
- Can I use CouchDB for free?
- Yes. CouchDB 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 CouchDB is typically brought in for.
- What can PlanetScale do that CouchDB cannot?
- PlanetScale covers Database Branching, Non-blocking Schema Changes, Insights, Horizontal Scaling. CouchDB covers Multi-master Replication, HTTP/JSON API, MapReduce Views, ACID Semantics.
