The EU-owned Supabase alternative
Supabase is a US-incorporated, Postgres-centric backend-as-a-service. HostStack is an EU-incorporated PaaS that runs your app and your managed Postgres together — GDPR-native, no US CLOUD Act.

When NOT to choose HostStack
Supabase is the better fit in some cases. Here's when we'd tell you so.
Migrate from Supabase
Open a HostStack account
Sign up at hoststack.dev with an email — no card during migration. Create a project in Nuremberg or Helsinki.
Move your database
Supabase is standard PostgreSQL. Provision a managed Postgres on HostStack and stream a pg_dump from your Supabase project straight into it.
Rehost your application
Connect your GitHub, GitLab, or Bitbucket repo. Anything that ran on Supabase Edge Functions becomes a HostStack web service or worker; framework auto-detection fills in build and start commands.
Replace Supabase-specific services
If you used Supabase Auth, Storage, or Realtime, wire in your own equivalent (a library, your own auth, or an S3 bucket). Your Postgres data and schema come across unchanged.
Cut over DNS
Point your records at HostStack and wait for the Let's Encrypt certificate to provision. Rotate any Supabase keys and decommission the old project.
Frequently asked questions
Is HostStack a good EU alternative to Supabase?
Yes, with one important difference in scope. Supabase is a Postgres-centric backend-as-a-service (managed Postgres plus auth, storage, realtime, and edge functions bolted on) and is a US-incorporated company (Supabase Inc.). HostStack is a general European PaaS: it runs your actual application — web services, workers, cron jobs — alongside managed Postgres, MySQL, MongoDB, and Redis, and it is EU-incorporated (Danish company MICCI) with data in Germany and Finland. If your main need is a managed Postgres you fully control plus somewhere to run your app, on EU-incorporated infrastructure, HostStack fits. If you specifically want Supabase's batteries-included auth/realtime/storage SDKs, Supabase is purpose-built for that.
Is Supabase GDPR-compliant and EU-hosted?
Supabase offers EU data regions (e.g. Frankfurt) and publishes a DPA, so you can keep data physically in the EU. But Supabase Inc. is a US-incorporated company, which means the US CLOUD Act can in principle compel disclosure regardless of where the data sits — the same Schrems II concern that applies to any US-incorporated provider with an EU region. HostStack is incorporated in Denmark (MICCI), so there is no US parent in the chain. For a clean data-residency and legal-incorporation story, EU incorporation is the differentiator.
How much does managed Postgres cost on HostStack vs Supabase?
HostStack managed Postgres starts at €4/month (Micro) and includes automated backups; a 3-node Patroni HA cluster is included on the €15 Standard and €50 Pro tiers with no HA add-on. Supabase's free tier pauses a project after about a week of inactivity, and the Pro plan is $25/month (including a compute credit) with additional compute billed per instance size. HostStack's free Starter Postgres does not expire. Always check current pricing on supabase.com before deciding — plans change.
How do I migrate from Supabase to HostStack?
Provision a managed PostgreSQL on HostStack, then stream a pg_dump of your Supabase database (it is standard Postgres) straight into it. Move any application code that ran on Supabase Edge Functions into a HostStack web service or worker, connect your GitHub/GitLab/Bitbucket repo, copy env vars with the CLI, and cut over DNS once TLS provisions. If you used Supabase Auth/Storage, plan for a replacement (your own auth or a library) since those are Supabase-specific.
