Neon DB vs Supabase

Neon and Supabase serve different architectural requirements for Postgres hosting, with pricing models that reflect their underlying infrastructure design. Neon operates as a serverless-first platform, capping its base offerings between $0.00 and $69.00/mo, which provides a maximum of 16 GB of RAM and 2 vCPU cores. Supabase scales much further, utilizing AWS-backed hardware to reach up to 256 GB of RAM and 128 vCPU cores, with a price ceiling hitting $7460.00/mo. While Neon provides up to 50 GB of disk storage in its upper tiers, Supabase is more restrictive on base storage, offering only 8 GB despite its massive compute potential.

• Neon charges a premium for storage growth at $0.35/GB, which is significantly more expensive than the $0.13/GB rate found on Supabase.
• Supabase offers a much higher memory ceiling of 256 GB, making it the only viable option for massive datasets that require keeping large indexes in RAM to avoid disk I/O bottlenecks.
• Outbound bandwidth penalties are nearly identical, with Neon charging $0.10/GB for excess egress compared to $0.09/GB at Supabase.
• Neon’s entry-level 0.25 vCPU core allocation is designed for cold-start serverless workloads, whereas Supabase’s minimum 0.5 vCPU provides a more stable baseline for persistent connections.

Neon is built for branching database states and ephemeral environments where compute intensity is bursty but total storage remains modest. Supabase functions as a traditional managed Postgres instance that relies on heavy-duty vertical scaling to handle high-concurrency applications. Choosing between them depends on whether your workload requires the flexibility of serverless storage separation or the raw power of large-instance memory allocations. Supabase is better for long-running, connection-heavy services, while Neon minimizes costs for developers who need to spin up and tear down database environments frequently.
