Cost Scale Analysis: When to choose MotherDuck over Supabase
Both MotherDuck and Supabase rely on identical hybrid flat-step pricing curves in this simulator. At equivalent workloads (free tier up to 10,000 MAUs, followed by a flat $25/mo up to 50,000 MAUs), their price trajectories align exactly, meaning the commercial decision pivots strictly on technical fit and compliance footprint.
We recommend evaluating baseline limits like API throughput (MotherDuck: Dynamic vs Supabase: Unlimited) to avoid hitting overage throttles.
Architectural Focus: Supabase
Supabase shines in high-velocity deployments. It prioritizes edge-native database allocations, making it ideal for decentralized serverless architectures.
