ScaleGrid vs Supabase

• Scalegrid scales storage capacity significantly higher, offering up to 15200 GB of disk compared to Supabase’s 8 GB limit, which forces heavy users onto local NVMe or block storage workarounds.
• Supabase implements a transparent overage model charging $0.13/GB for storage and $0.09/GB for network egress, whereas Scalegrid pricing is largely opaque and bundled into the base instance tiers.
• Memory allocation at the high end favors Scalegrid with 512 GB of RAM, doubling the 256 GB maximum available on Supabase’s managed PostgreSQL infrastructure.
• Base entry points diverge sharply, with Scalegrid requiring $13.00/mo for minimal 1 GB footprints, while Supabase provides a free tier starting at $0.00/mo for 0.5 GB of memory.

Scalegrid functions as a specialized database management layer, often deploying on top of AWS, Azure, or GCP. This allows for massive vertical scaling of compute and storage, making it the preferred choice for enterprise-grade workloads requiring substantial 64 vCPU allocations. You pay for the underlying cloud provider's hardware premiums, but you avoid the aggressive storage constraints found in Supabase. Because Scalegrid provides managed HA and replication settings that are highly configurable, the cost is tied to the provisioned infrastructure rather than per-gigabyte usage spikes.

Supabase operates as a full-stack platform, meaning your database is bundled with other services. Their 0.5 vCPU to 128 vCPU range is impressive, but the limited disk allocation makes it better suited for applications with smaller data footprints but high concurrent connection requirements. When choosing between these two, prioritize Scalegrid if your primary concern is massive disk persistence and high-availability replication control, or select Supabase if your architecture benefits from a platform that packages compute and network egress into a predictable monthly invoice.
