Microsoft Azure vs Supabase

• Azure provides a predictable entry at $7.59/mo for 1 GB of RAM, whereas Supabase offers a free tier before jumping to paid plans that scale up to 256 GB of RAM for $7460.00/mo.
• Disk overages are comparable, with Azure charging $0.12/GB and Supabase slightly higher at $0.13/GB.
• Azure includes significantly larger baseline storage volumes up to 250 GB, while Supabase limits base storage to just 8 GB, forcing reliance on add-on storage for large datasets.
• Both providers align on network egress costs, both charging $0.09/GB for data transferred out of the database cluster.

Azure Database for PostgreSQL focuses on enterprise-grade stability, typically running on standard SSD tiers that provide consistent IOPS for traditional relational workloads. Scaling these instances involves predefined tiers that cap out at 16 GB of RAM and 4 vCPU cores. This architecture is built for predictable, steady-state applications that do not require the massive vertical scaling often seen in specialized cloud-native environments. You are paying for the maturity of the underlying infrastructure and integration with the broader Microsoft ecosystem, which feels distinct from the hardware-heavy, high-compute focus of Supabase.

Supabase targets developers who need to scale Postgres far beyond the limitations of standard Azure instances, utilizing massive instances with up to 128 vCPU cores. While Azure offers a safer, more rigid cost structure for mid-sized applications, the storage tax on Supabase becomes significant once you exceed the small 8 GB base allocation. Choosing between these platforms rests on whether your database requires the deep vertical compute capacity of high-end instances or the storage density and managed reliability inherent in Azure’s standard hardware deployments.
