Best Self-hosted Alternatives to Grafbase

Supabase is an open source Postgres development platform for building web, mobile, and AI applications. It combines PostgreSQL with a set of services for authentication, instant APIs, realtime updates, serverless functions, and file storage.

Key Features

• Dedicated PostgreSQL database with SQL, roles, and Row Level Security
• Auto-generated REST APIs from your database schema
• Optional GraphQL API via a PostgreSQL extension
• Authentication and authorization with JWT-based sessions and OAuth2 support
• Realtime subscriptions over WebSockets driven by PostgreSQL changes
• File storage service with access control policies backed by Postgres
• Edge/serverless functions for custom backend logic
• Vector/embeddings support using Postgres extensions (for semantic search and RAG patterns)
• Web-based dashboard for managing projects, data, and configuration

Use Cases

• Replace or self-host a Firebase-like backend for apps with Postgres
• Build internal tools and SaaS backends with auth, APIs, and storage
• Create AI-enabled applications using Postgres vector search and embeddings

Limitations and Considerations

• Some functionality relies on multiple cooperating components (database, realtime, auth, storage, gateway), which increases operational complexity compared to a single service
• Feature set and behavior can vary depending on the chosen self-hosting setup and enabled extensions

Supabase provides a cohesive backend stack around PostgreSQL while keeping data ownership and portability. It is well-suited for teams that want a modern developer experience with SQL and strong database-native security controls.

Hasura GraphQL Engine provides instant, realtime GraphQL and REST APIs over your data sources by introspecting schemas and exposing a composable, secure API surface. It supports multiple backends and connector SDKs for adding custom business logic, and includes an admin console and migration tooling for managing schema and metadata.

Key Features

• Instant GraphQL APIs generated from database schemas with support for queries, mutations, subscriptions (realtime).
• Fine-grained row- and column-level access control and permission rules.
• Database event triggers and webhooks for serverless workflows and asynchronous processing.
• Data Connectors architecture (V3) enabling Postgres, MongoDB, ClickHouse, MS SQL Server and other sources.
• Connector SDKs for writing custom business logic in TypeScript, Python, and Go.
• Admin console and migration tooling for schema management and metadata versioning.
• Remote schemas and schema stitching to merge custom GraphQL services into a single endpoint.
• Container-friendly deployment with Docker and orchestration support for cloud/Kubernetes environments.

Use Cases

• Rapidly expose an existing database as a secure, realtime GraphQL API for web and mobile apps.
• Build event-driven pipelines by triggering functions or webhooks on database changes.
• Compose data from multiple sources into a unified API for microservices and analytics.

Limitations and Considerations

• Full feature parity depends on the connected data source; some advanced features vary by connector and database capabilities.
• Operational behavior (performance, caching, realtime scalability) is influenced by the underlying datastore and deployment topology.

Hasura is designed to accelerate API development by automating schema-to-API creation and providing production-oriented features for access control, subscriptions, and eventing. It is commonly used to modernize data access, integrate heterogeneous data sources, and power realtime user experiences.

Graphweaver is a code-first GraphQL backend that connects multiple data sources behind a single GraphQL API. It focuses on fast bootstrapping with generated CRUD operations while keeping everything fully customizable in TypeScript.

Key Features

• Connect multiple data sources (SQL databases and external APIs) behind one GraphQL schema
• Instant CRUD GraphQL API with filtering, sorting, and pagination
• Cross-source filtering to query and filter across different backends
• Code generation to introspect supported databases and generate TypeScript resolvers
• Granular security controls including RBAC plus row-level and column-level permissions
• Built-in, extensible admin panel for browsing and managing connected data

Use Cases

• Build a unified GraphQL gateway over multiple databases and SaaS/REST services
• Rapidly scaffold an internal admin tool for operational data management
• Add fine-grained authorization to CRUD APIs without losing code-level control

Graphweaver is well-suited for teams that want Hasura-like acceleration while keeping a standard, hackable GraphQL server and UI that can be adapted to production requirements.
