Scaleway vs Supabase

Scaleway and Supabase offer vastly different entry points for managed database hosting. Scaleway’s managed instances start at $0.10/mo and scale up to $1861.50/mo, providing a consistent 20 GB of storage across their tiers, which is useful for predictable development cycles. In contrast, Supabase features a free entry tier and scales up to $7460.00/mo, utilizing AWS-backed infrastructure. While Supabase offers a wider range of vCPU cores, topping out at 128 vCPU compared to Scaleway’s 48 vCPU, their included storage is significantly lower, starting at just 0.5 GB and peaking at 8 GB.

• Scaleway is more cost-effective for egress-heavy workloads, charging $0.01/GB for overages, whereas Supabase hits significantly harder at $0.09/GB.
• Disk storage overages are nearly identical, with Scaleway charging $0.12/GB and Supabase charging $0.13/GB.
• Scaleway guarantees a minimum of 2 GB of RAM at the bottom end, while Supabase starts as low as 0.5 GB for lightweight hobbyist projects.
• Both providers support high-end scaling to 256 GB of RAM for memory-intensive PostgreSQL operations, though Scaleway keeps storage footprints more uniform for their managed instances.

Choosing between these providers depends on your specific traffic patterns and architectural requirements. Scaleway’s managed database environment is designed for engineers who want fixed storage allocations and lower network transfer penalties, often performing well for self-hosted backend services running on European infrastructure. Supabase is better suited for applications that leverage a broader BaaS feature set, provided you can handle the higher egress costs and the restricted disk capacity inherent in their managed instances. You are essentially choosing between Scaleway’s infrastructure-first consistency and the higher-ceiling, feature-rich ecosystem offered by Supabase.
