European-only alternative to Supabase.

Supabase is the open-source Firebase alternative: hosted Postgres + Auth + Storage + Edge Functions + Realtime with a polished developer experience. Supabase Inc. is a Delaware US corporation; the EU regions (Frankfurt, Ireland, London, Paris) run on AWS infrastructure under both Supabase and AWS US-jurisdictional control. The good news: Supabase is open-source. You can self-host the entire stack on EU infrastructure with full feature parity - that is the sovereign alternative we deploy for clients.

"EU region" is not sovereignty. Four questions decide it.

Data residency tells you where the bits sit. Sovereignty tells you which legal system can compel access. The answer must hold on all four - or the stack is not sovereign.

Residency

Where is the data physically stored?

Not "in the cloud" - which datacenter, in which country, under which jurisdiction.

Subprocessors

Who else is in your data path?

Every vendor that touches the data: the CDN, the email relay, the error tracker, the analytics pipe.

Jurisdiction

Whose laws can compel disclosure?

A US-headquartered provider falls under FISA 702 and the CLOUD Act - even when the bits sit in Frankfurt.

Key custody

Who actually holds the encryption keys?

If the cloud provider holds both the data and the keys, the data is readable by them - regardless of any DPA.

Fails AWS · Azure · GCP · EU region

Fails on jurisdiction and key custody.

EU bits, US-headquartered parent, US subprocessors in the default path, provider-managed keys.

Passes Binadit managed stack

Passes on all four.

EU-hosted on EU-headquartered infrastructure. Zero US subprocessors in the default path. Customer-held or EU-KMS keys. Listed by name in your Article 28 DPA.

Why teams are exiting Supabase

Supabase exits we have run come from one consistent trigger: a B2B SaaS that picked Supabase for its DX, grew to enterprise customers, and discovered that "Supabase Frankfurt on AWS Ireland" is two layers of US-jurisdictional processors that fail Schrems II analysis. The Supabase team itself has publicly discussed the data sovereignty constraints on their blog. Self-hosting Supabase on EU infrastructure preserves the full DX (the same supabase-js client works) while moving to full EU jurisdiction.

Supabase services and their EU-only equivalents

A migration is not "swap one box for another". The mapping below is what we run for clients leaving Supabase on Schrems II grounds - full EU jurisdiction, no US parent in the data path.

Postgres (managed)

What we run instead
Binadit Managed Cloud Platform. PostgreSQL or MySQL with Patroni for failover and pgBackRest for point-in-time recovery.
Engineering note
Streaming replication lets us cut over with seconds of downtime rather than a maintenance window, and restores are tested on a schedule instead of assumed.

Auth (GoTrue)

What we run instead
Binadit Managed Cloud Platform. Keycloak or Authentik as the identity provider, with OIDC and SAML.
Engineering note
GoTrue is part of the open Supabase stack; self-hosting preserves the JWT-based auth with social logins, magic links, MFA.

Storage (S3-compatible)

What we run instead
Binadit Managed Cloud Platform. MinIO or Ceph RGW, S3-compatible.
Engineering note
Supabase Storage is a service layer over S3-compatible storage; works with any EU S3 backend.

Edge Functions (Deno)

What we run instead
Binadit Managed Cloud Platform. Knative or OpenFaaS on your Kubernetes cluster.
Engineering note
Edge Functions are Deno runtimes; the self-hosted equivalent runs on any EU container platform.

Realtime (Postgres CDC)

What we run instead
Binadit Managed Cloud Platform. PostgreSQL logical replication into a websocket layer, or NATS for fan-out.
Engineering note
Realtime is open-source; self-hosting preserves the WebSocket-based pub/sub.

Vector embeddings (pgvector)

What we run instead
Binadit Managed Cloud Platform. pgvector on PostgreSQL, or Qdrant for larger embedding sets.
Engineering note
For dedicated vector workloads, Qdrant Cloud EU is a sovereign-by-default alternative.

Studio (admin UI)

What we run instead
Binadit DevOps & Support. pgAdmin or Metabase for data access, with Grafana for operational views.
Engineering note
Studio is part of the self-hosted distribution.

Database backups

What we run instead
Binadit Managed Cloud Platform. restic and pgBackRest for data, Velero for Kubernetes state, to isolated EU storage.
Engineering note
WAL-G with EU object storage backend is the production-grade pattern.

API (PostgREST)

What we run instead
Binadit Managed Cloud Platform. Traefik or Kong, with rate limiting and OIDC at the edge.
Engineering note
PostgREST is open-source; self-hosting preserves the REST API generation.

CLI / Migrations

What we run instead
Binadit DevOps & Support. kubectl, Terraform and GitLab CI, with project-specific wrappers where they help.
Engineering note
The Supabase CLI supports `--db-url` to point at self-hosted instances.

How we migrate off Supabase

A typical mid-market migration runs in three phases. The numbers below assume a 6-10 person engineering team and a moderately complex application stack.

  1. Days 1-5

    Self-hosted Supabase deployment

    Deploy self-hosted Supabase stack on Binadit (Docker Compose or Kubernetes). Configure auth providers, storage backend, Edge Functions runtime. Set up monitoring and backups.

  2. Days 6-14

    Database + auth migration

    Postgres dump+restore to self-hosted instance. User accounts migrated via auth provider data export. Storage buckets mirrored. Edge Functions redeployed.

  3. Weeks 2-3

    Application cutover

    Application config updated to point at self-hosted Supabase URL. Same supabase-js client, same RLS policies, same auth flows. Cutover with a verification window.

Self-hosted Supabase on a single small VM replaces Supabase Pro at $25 per project per month plus per-project usage. For multi-project workloads, savings compound: a typical Supabase team plan ($599/month) becomes €40-100/month in raw infrastructure plus the managed-partner fee if you don't want to operate it yourself. Plus full EU jurisdiction.

Frequently asked questions

View all frequently asked questions

Is Supabase's EU region (Frankfurt, Ireland) sufficient for GDPR?
Residency yes, sovereignty no. Supabase Inc. is US-headquartered, and the Frankfurt/Ireland regions run on AWS - also US-jurisdictional. For Schrems II analyses, both layers are exposed.
Does self-hosted Supabase have full feature parity?
Yes for the core stack: Postgres, Auth (GoTrue), Storage, Edge Functions, Realtime, Studio, PostgREST. The supabase-js client works identically. The features that aren't in self-hosted: paid-tier features like team management UI and integrated logging dashboards (you build those with Loki + Grafana on EU infra).
How operationally complex is self-hosted Supabase?
For single-environment production, a single modest VM with Docker Compose is sufficient and operationally manageable for an experienced engineering team. For multi-environment or HA setups, Kubernetes with Helm chart is the production pattern; we operate this for clients.
Does the supabase-js client need code changes?
Just one: the URL points at your self-hosted instance instead of `*.supabase.co`. RLS policies, auth flows, storage URLs, realtime subscriptions - all unchanged.
What about managed Supabase EU equivalents?
There are emerging EU-headquartered offerings (Supascale, Supafast - both early-stage), but the production-ready answer is self-hosted Supabase managed by an EU partner. We deploy and operate this exact pattern.
How long does a Supabase exit take?
For a single-environment project (one Postgres, basic auth, a few buckets): 1-2 weeks elapsed. For multi-environment or large-data setups: 3-6 weeks. The migration is mechanically clean because everything is open-source upstream.
