Supabase is the open-source Firebase alternative that gives you a Postgres database, authentication, file storage, realtime subscriptions, and auto-generated APIs in one platform, and one of its biggest draws is that you can self-host the whole thing. Run it yourself and you get the entire Supabase stack on infrastructure you control, with your data in your own environment and no usage-based cloud bill. This guide explains what self-hosting Supabase actually involves, how the setup works, the server you need, where to host it, and when the managed cloud is the smarter call.
Self-hosting Supabase is more involved than running a single app, because Supabase is really a collection of services working together. But it is well-documented and entirely achievable, and for the right project the control and cost savings are worth it. Here is how to do it properly.
The short answer
Supabase self-hosts as a set of Docker containers, Postgres, authentication, the API layer, realtime, storage, and the Studio dashboard, run together with Docker Compose. You clone the official repository, set your configuration and secrets in an environment file, and bring the stack up. It needs a server with enough resources to run several services, so a small VPS or a platform like Railway is the natural home.
What Supabase is and what self-hosting includes
Supabase bundles several open-source components into a coherent backend platform, and when you self-host, you run all of them yourself. Understanding the pieces makes the setup far less intimidating.
PostgreSQL. At the center sits a Postgres database, the source of truth for your data. Everything else in Supabase is built around it, which is part of why developers like it: you get a real, full-featured relational database rather than a proprietary store.
Authentication. A service handles user sign-up, login, and sessions, including email and social logins, so you get a complete auth system without building one.
The API layer. Supabase automatically exposes your database as a REST API, and a GraphQL option, so your app can talk to the database through a clean interface without you writing boilerplate endpoints.
Realtime, storage, and Studio. A realtime service pushes database changes to clients over websockets, a storage service handles file uploads, and Studio is the web dashboard you use to manage everything, the same interface you see in the hosted version. A gateway ties the services together behind a single entry point.
When you self-host, all of these run as containers on your server, coordinated so they behave exactly like the managed product, just on your own infrastructure.
Why self-host Supabase?
Supabase offers an excellent managed cloud, so self-hosting is a deliberate choice with specific benefits.
Cost control. The managed service is usage-based, which is convenient but can grow as your project does. Self-hosting means you pay only for the server, which for a steady workload can be considerably cheaper, with a predictable monthly bill.
Data ownership and residency. Your database and all its data live on infrastructure you control, in the region and environment you choose. For privacy requirements, compliance, or simply a preference to own your data, that is a strong reason.
No limits and full control. You are not bound by a plan’s limits, and you have complete access to the underlying Postgres and every service, which lets you tune, extend, and integrate freely. Because it is all open source, there is no lock-in.
The trade-off is operational responsibility, since you run several services, handle updates, and own backups. For some projects that is well worth it, and for others the managed cloud is the better use of time, which we will come back to.
How to self-host Supabase
The official self-hosting path uses Docker Compose, and the process is methodical rather than difficult. Here is the shape of it.
1. Get the repository. You clone Supabase’s official self-hosting setup, which includes the Docker Compose file defining all the services and a sample environment configuration. This is the blueprint for the whole stack.
2. Configure your environment. You copy the example environment file and set your own values: database passwords, the secret keys and tokens the services use to authenticate with each other, your site URL, and any email or social login settings. Generating strong, unique secrets here is essential, since these protect your entire backend.
3. Bring the stack up. A single Docker Compose command starts all the services together. After a moment, you have Postgres, auth, the API, realtime, storage, and Studio running and talking to each other. You can open Studio in your browser and start working with your database.
4. Put it behind HTTPS. For anything beyond local testing, you place the stack behind a reverse proxy with a valid certificate so it is served securely over HTTPS, and you point your domain at it. Your applications then connect to your self-hosted Supabase exactly as they would to the cloud version, just with your own URL and keys.
From there, you use Supabase as normal: define tables, set up authentication, write row-level security policies, and connect your app with the client libraries. Everything works the same, because it is the same software.
Server requirements: what you need to run it
Because Supabase runs several services at once, it asks more of a server than a single lightweight app. This is the main thing to plan for.
Memory and CPU. Running Postgres plus the auth, API, realtime, storage, and gateway services together needs a server with a reasonable amount of RAM, more than the smallest instances that suit a single-container app. A small but not tiny VPS is the right starting point, with headroom to grow as your usage increases.
Storage. Your database and any uploaded files need disk space, so size storage for your data and choose a host that lets you expand it. Crucially, set up backups of the Postgres data, since that is your application’s heart.
Persistence and networking. The containers use volumes to persist data across restarts, which the official setup configures, and the services communicate over an internal network. You mainly need to ensure the gateway is reachable and secured, and that data volumes are backed up.
None of this is exotic, but it does mean choosing a server with enough resources rather than the cheapest option. Plan for a mid-tier small server rather than the bottom rung.
Where to host self-hosted Supabase
You need a server that can run the Supabase stack reliably and stay online. A few options fit well depending on how much you want to manage.
A managed cloud server on Cloudways gives you a properly sized server without the administration overhead, which suits running a multi-service stack like Supabase with a predictable monthly cost. A VPS from Hostinger is a more affordable route if you are comfortable managing the server yourself and want full control over the Docker setup. For a more hands-off deploy, a platform like Railway can run the containers with less infrastructure work, and it pairs naturally if your application also lives there, with private networking between your app and your backend. Whichever you choose, size it for several services, keep the Postgres data backed up, and serve it over HTTPS.
Host your Supabase stack on Railway
Run the Supabase services with far less infrastructure work, keep your app and backend together with private networking, and scale as your project grows. The simplest way to self-host Supabase.
Security: getting the important parts right
Self-hosting Supabase means you own its security, and a few things matter more than the rest.
Set strong, unique secrets. The keys and tokens in your environment file authenticate the services and protect access to your data. Generate strong, unique values, never reuse the examples, and keep them safe. Weak or default secrets are the most common self-hosting mistake.
Use row-level security. Supabase exposes your database through an API, so row-level security policies in Postgres are what control who can read and write what. Configure them carefully, because without good policies an exposed API can leak or accept data it should not.
Serve over HTTPS and protect the dashboard. Put everything behind HTTPS, and make sure Studio and the database are not openly accessible to the internet without protection. Restrict access to the management interface to people who should have it.
Back up Postgres. Automated, off-server backups of your database protect you against server failure. This is the one safeguard you cannot skip, since your database holds everything.
Self-hosted vs the managed cloud
It is worth being honest about when self-hosting is and is not the right call. Self-host Supabase when you want cost predictability at steady scale, data residency or privacy control, or full access to the underlying services, and you are comfortable running a multi-service stack and maintaining backups and updates.
Use the managed Supabase cloud when you would rather not operate the infrastructure, when you want automatic scaling, backups, and updates handled for you, or when your time is better spent building your product than running a backend. The managed service is genuinely good, and for many teams, especially early on, it is the more sensible choice. There is no wrong answer: self-host for control and cost discipline when you have the capacity, use the cloud when convenience matters more. Many projects even start on the cloud and move to self-hosting later, or the reverse, since it is the same software either way.
One nice detail for AI projects: self-hosted Supabase includes Postgres, which means you can enable the pgvector extension and use it as a vector database alongside your app data. Our pgvector guide covers how that works.
Frequently asked questions
Can you self-host Supabase? Yes. Supabase is open source and provides an official self-hosting setup using Docker Compose. You run the full stack, Postgres, auth, the API, realtime, storage, and the Studio dashboard, on your own server, and it behaves like the managed cloud version.
How hard is it to self-host Supabase? It is more involved than running a single app because Supabase is several services, but the official Docker Compose setup makes it methodical rather than difficult. You clone the repository, set your secrets and configuration, and bring the stack up. The main extra effort is sizing the server, securing it, and maintaining backups.
What server do I need for self-hosted Supabase? One with enough resources to run several services at once, so a small-to-mid VPS rather than the tiniest instance. Plan for a reasonable amount of RAM, disk space for your database and files, and backups. A managed server on Cloudways, a Hostinger VPS, or a platform like Railway all work.
Is self-hosting Supabase cheaper than the cloud? For steady workloads it often is, because you pay a predictable server cost instead of usage-based pricing that grows with your project. For light or highly variable use, the managed cloud can be cheaper and simpler. Factor in the value of your time spent operating it.
Does self-hosted Supabase have all the features? It includes the core platform: database, auth, auto-generated APIs, realtime, storage, and Studio. Some of the newest or most managed-specific features may lag the cloud, and a few conveniences are handled for you only in the managed version, but the essential Supabase experience is fully there.
Can I use self-hosted Supabase as a vector database? Yes. Because it runs real Postgres, you can enable the pgvector extension and store and query embeddings alongside your application data, which is handy for adding AI search or RAG features to a Supabase-backed app.
The bottom line
Self-hosting Supabase gives you the entire open-source backend platform, database, auth, APIs, realtime, and storage, on infrastructure you control, with predictable costs and full ownership of your data. The setup uses Docker Compose and is methodical: clone the repository, set strong secrets, bring the stack up, and serve it securely over HTTPS. The main thing to plan for is a server with enough resources to run several services, hosted somewhere reliable like a Cloudways server or Railway, with automated Postgres backups you have tested. Be honest about whether the operational work is worth it for your project: if it is, self-hosting Supabase is powerful and rewarding, and if it is not, the managed cloud is an excellent alternative.
