Cost Scale Analysis: When to choose Clerk over PlanetScale
PlanetScale is built on linear usage-based metrics, while Clerk operates on flat steps.
Under 7.5k MAUs: Both systems are highly efficient, scaling down to a clean $0/mo pricing footprint.
Between 10k and 50k MAUs: Clerk locks in a flat cost of $25/mo. PlanetScale will trigger automatic volume overages ($23 base + $0.007/user), which drives monthly costs to $100+ at 20k MAUs.
At Enterprise Scale (>100k MAUs): The cost advantage for Clerk widens drastically due to its gentle overage factor ($0.0012/user) versus PlanetScale ($0.007/user). Choose Clerk to handle high database volume with lean budgets.
Architectural Focus: PlanetScale
PlanetScale shines in high-velocity deployments. It prioritizes edge-native database allocations, making it ideal for decentralized serverless architectures.
