The short version

Only MotherDuck has a free tier, so it costs nothing to try first.
Each has a real cost: MotherDuck the free Lite plan caps compute at 10 hours per month, which limits it to light or hobbyist workloads.; PlanetScale eBS High Availability requires 3-node configuration with replication overhead
They diverge on capability: MotherDuck covers Serverless DuckDB instances, PlanetScale covers Database Branching.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

MotherDuck

The free Lite plan caps compute at 10 hours per month, which limits it to light or hobbyist workloads.
Business plan usage charges on top of the $250/month base can make costs less predictable than flat-rate competitors.
There are no academic or non-profit discounts, unlike some competing data platforms.
Annual billing requires going through a sales conversation rather than a self-serve toggle.

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
