What is Hasura?
Hasura is an open-source platform that automatically generates GraphQL APIs from existing databases. Instead of implementing API endpoints manually, you connect Hasura to a database and immediately get a complete GraphQL interface. This works without additional application code. The platform can be self-hosted, keeping it fully under the operator's control.
Core features
- Automatic API generation: Hasura reads the database schema and generates GraphQL queries, mutations and subscriptions directly from it.
- Real-time queries: Live queries and subscriptions are built in. Clients receive data changes without additional infrastructure such as WebSocket servers.
- Access control: Role-based permissions can be configured directly in Hasura, which is especially relevant in multi-tenant architectures.
- Authentication integration: Hasura delegates authentication to external services via JWT or webhooks, rather than handling it itself.
- Microservices connectivity: Remote Schemas and Actions allow external services and existing REST APIs to be integrated into the GraphQL interface.
- Self-hosting: The platform runs entirely on your own infrastructure, typically via Docker or Kubernetes.
Who is Hasura for?
Development teams that need to set up a GraphQL backend quickly, without writing their own API layer from scratch. This is particularly useful for mobile and web apps where the database schema is already in place. Teams that need complex access rules across multiple tenants will find the permission layers save real time compared to writing resolvers manually.
The barrier to entry is not the concept but the operations side. Anyone without prior experience with Docker or Kubernetes will spend time on setup before the first query runs. Complex configurations, such as nested permission rules or connecting heterogeneous data sources, require a solid understanding of Hasura's metadata structure.
Context & alternatives
Hasura belongs to the category of API generators and backend-as-a-service tools. The key difference from classic BaaS platforms: you retain control over your own database and infrastructure. Those who prefer a managed solution can look at alternatives such as Supabase or PostGraphile. Supabase offers a similar approach with a stronger focus on PostgreSQL and an integrated hosting offering. PostGraphile is leaner, but less flexible when it comes to integrating external services. For GraphQL-first development with full database ownership, Hasura is a stronger fit than a hosted all-in-one service.
