How Much RAM Does Self-Hosted Supabase Need?
One of the first questions developers ask when self-hosting Supabase is simple: how much RAM do I need?
The answer depends on the workload.
Supabase is a complete backend stack. It can include PostgreSQL, Auth, Storage, Realtime, Studio, API services, connection pooling, and more.
Small Projects
A small project with limited traffic may operate with a smaller resource allocation. However, having some memory headroom is important because several Supabase services run together.
Growing Applications
As users and requests increase, memory usage can also increase. For example, your application may have:
More database connections More realtime subscriptions Larger queries More authenticated users More storage activity More API requests Each workload can contribute to resource usage.
Why More RAM Helps
When the server has enough memory, PostgreSQL and other services have more room to operate without constantly competing for limited resources.
If memory becomes consistently constrained, you may experience slower performance or service instability.
Monitor Before Upgrading
Do not upgrade blindly. Look at memory usage over time and identify whether the application is actually approaching its resource limit.
Hostwares provides dedicated CPU and RAM resources for its self-hosted Supabase offering, with the ability to resize resources as requirements change. The goal is simple: enough RAM for today's workload, plus reasonable room for tomorrow.
