Best 10 Supabase Alternatives in 2026: Open Source and Managed Picks

Introduction

Appwrite is the closest all-in-one match among Supabase alternatives, and Neon is the pick if you only need Postgres. This list covers 10 backends and databases, from open-source and self-hosted options to managed and serverless ones.

Why people look for alternatives

Teams leave Supabase (or skip it) for practical reasons, not because it's bad. Common triggers:

• Data model: some want NoSQL, document-style or GraphQL-first instead of Postgres with REST.
• Hosting: some need self-hosted only, some want fully managed, and some are tied to a cloud like AWS.
• Scope: some want more bundled features (auth, functions, storage). Others want a lean database and nothing else.
• Cost and scale: pricing predictability and scaling needs push people to compare options.

Quick comparison table

This table is a starting point. The details are in each entry below.

1. Firebase

Best for: teams building mobile and web apps who are comfortable with NoSQL and Google's ecosystem.

Firebase is Google's backend platform. Supabase is open source and runs on Postgres. Firebase is proprietary and NoSQL.

It offers Firestore and Realtime Database, authentication, hosting and cloud functions. What stands out is the pairing of Firestore and Realtime Database with built-in auth.

2. Appwrite

Best for: teams who want an open-source, Supabase-style all-in-one backend.

Appwrite covers auth, databases, storage, functions and messaging. You can self-host it or use the cloud service.

The big difference from Supabase is the document-style database instead of Postgres. Its standout is messaging, bundled alongside the core backend services.

3. Nhost

Best for: developers who like Postgres but prefer GraphQL.

Nhost is an open-source backend built on Postgres and Hasura, with auth, storage and serverless functions. It is GraphQL-first, while Supabase is REST-first.

The best part is the Hasura GraphQL layer, which sits directly on your Postgres data.

4. PocketBase

Best for: solo developers and small projects that want a tiny, self-hosted backend.

PocketBase ships as a single Go executable with embedded SQLite, auth, file storage and a realtime API.

It is self-hosted only. There is no managed cloud, so you run it yourself. Its standout is the one-file deployment.

5. Neon

Best for: teams who only need serverless Postgres.

Neon focuses on the database layer, with branching and autoscaling to zero. It has fewer bundled backend features than Supabase, so you pair it with your own auth and APIs.

Database branching is the feature to look at.

6. Convex

Best for: TypeScript teams building reactive, real-time apps.

Convex combines a TypeScript-based database, server functions and real-time sync.

It uses a document-relational model instead of SQL. Moving from Supabase means rethinking queries and schema, not just swapping a connection string. The standout is automatic real-time sync.

7. AWS Amplify

Best for: teams already committed to AWS.

AWS Amplify is AWS's framework and hosting service for full-stack apps, with auth, data, storage and APIs.

It is more configurable than Supabase, but also more complex and tied to the AWS ecosystem. The upside is access to the wider AWS service catalog.

8. Xata

Best for: developers who want Postgres with a friendly interface and built-in search.

Xata offers branching, search and a developer-friendly interface. It is mainly a database service, so it lacks Supabase's built-in auth and functions.

Integrated search is the main draw.

9. Directus

Best for: teams that need an admin app or headless CMS over an existing SQL database.

Directus wraps any SQL database with instant REST and GraphQL APIs. Its no-code interface focuses on data management.

The standout is the admin app that sits on top of your existing database.

10. Back4app

Best for: teams who want a managed Parse Server backend.

Back4app is a backend-as-a-service built on Parse Server, with database, auth, cloud functions and real-time features.

It offers a managed Parse environment and also supports containers. Managed Parse hosting is what sets it apart.

How we picked these tools

The picks cover different data models, hosting styles and levels of complexity. We based selection on each tool's published features, not hands-on testing, ratings or scores.

Criteria: overlap with Supabase's job, open source versus proprietary, and database-only versus full backend. The order is editorial, not a measured ranking.

Frequently asked questions

What is the closest open-source alternative to Supabase?

Appwrite is the closest all-in-one option, with self-hosting or cloud and a document-style database. Nhost keeps Postgres but is GraphQL-first. PocketBase is a self-hosted-only single executable on SQLite.

Which alternative should I pick if I only need Postgres?

Neon and Xata are the database-focused options. You give up bundled auth and functions, so you'll need to add those yourself.

Can I self-host these alternatives?

Appwrite, Nhost, PocketBase and Directus are open source and self-hostable. Firebase, Neon, Convex, AWS Amplify and Xata are presented here as managed services, as is Back4app's managed Parse environment.

The verdict

Appwrite is the strongest overall pick for an open-source, all-in-one backend with flexible hosting. Neon is the runner-up for Postgres-only needs, and Nhost fits Postgres with GraphQL.

PocketBase suits tiny self-hosted projects, while Firebase and AWS Amplify make sense inside Google or AWS ecosystems. Match your choice to your data model and hosting needs.
