Stack vs Supabase

This compares self-hosted Supabase and Stack from a workflow point of view.

BenefitStackSupabase (self-hosted)
Deploy anywhereKubernetes-first, runs on any cluster (k3s, k3d, managed, bare metal).Docker Compose friendly, great for single-host setups.
Production parityDevelopment matches production because it is the same operator, CRDs, and manifests.Local dev is simple but can diverge from production Kubernetes.
App definitionOne StackApp manifest that declares services and components.Multiple services wired in docker-compose plus project config.
Secrets handlingSecrets are created and managed as Kubernetes Secrets.You manage env files and compose secrets manually.
Multi-app isolationNamespaces, per-app DBs, per-app services.Typically one project per compose stack.
ExtensibilityAdd services and operators alongside Stack components.Extend compose with extra services.
Gateway routingNGINX routes /auth, /rest, /realtime, /storage in one place.Supabase API gateway handles its internal services.
Operations modelDeclarative, reconciled by the operator.Imperative docker lifecycle.

When Stack is a good fit

  • You want a Kubernetes-first platform that runs the same way locally and in production.
  • You deploy multiple apps or namespaces and want repeatable isolation.
  • You want a single manifest that declares components and services.
  • You want Stack to generate and manage secrets for you.

When Supabase is a good fit

  • You want the fastest possible single-host setup with docker-compose.
  • You want Supabase UI and built-in workflows with minimal Kubernetes knowledge.
  • You are experimenting locally and do not need production parity yet.

If you want a quick migration path, Stack can run Postgres, Auth, REST, Storage, and Realtime equivalents while you keep your application code unchanged.
