Introduction to Supabase and Hasura
Supabase and Hasura are popular platforms for building data-driven applications, but they target different use cases. Supabase positions itself as an open-source Firebase alternative, offering a managed PostgreSQL database, REST API, authentication, storage, and real-time features—all out of the box. Hasura focuses on instant, scalable GraphQL APIs for existing PostgreSQL databases, and primarily serves projects needing powerful query capabilities without managing underlying storage.
This comparison explores architecture, database and API strengths, authentication, real-time features, compliance, pricing, and suitability for your stack.
Key Takeaways
- Supabase is a full-stack backend solution, best for those needing managed Postgres, REST/GraphQL APIs, real-time data, and built-in auth.
- Hasura specializes in generating scalable GraphQL APIs over Postgres—ideal for teams prioritizing advanced API queries and customizable permissions.
- Both provide core security features for data-level authorization, but differ in approach: Supabase uses Row Level Security, Hasura applies role-based rules.
- Both offer free tiers with usage limits; pricing and actual compliance status (GDPR, SOC 2) are not fully documented publicly.

Core Architecture and Approach
Supabase targets developers who want a managed database and backend stack, including authentication, real-time subscriptions, REST, and GraphQL endpoints, plus object storage. It’s close in spirit to Firebase, but runs on standard PostgreSQL. Supabase is designed to minimize setup—provision a project and you get a ready-to-use backend.
Hasura differs in philosophy: it doesn’t host your database. Instead, it connects to your existing Postgres database and instantly exposes it through a high-performance, auto-documenting GraphQL API. Its focus is making your data API-driven, rather than delivering a managed database or auth solution.
Database and API Capabilities
With Supabase, you get a hosted Postgres database, exposed via REST APIs but also supporting GraphQL (though not as its primary interface). Supabase shines for developers needing quick access to both data and common backend tools: auth, file storage, and real-time services.
Hasura’s main value is GraphQL. Point Hasura to your Postgres instance and it generates a schema, offering sophisticated filtering, joins, permissions, subscriptions, and more via GraphQL. REST or real-time access is not core; if you need those, Supabase may fit better.
Select Supabase for rapid prototyping and broad API requirements (REST, auth, real-time). Opt for Hasura where you need GraphQL-first API design, sophisticated query support, and already have Postgres infrastructure.
Authentication and Security Models
Supabase provides a ready-to-use authentication system for email, OAuth, and other flows, with integration at the database level. Access is secured by Row Level Security (RLS): unless you define policies for a table, outside access is denied.
Hasura handles security using permission rules and roles: you specify which GraphQL operations are allowed for different user types, down to table or even column level. Authentication itself requires integration with your existing auth provider.
Both models offer robust data-level security, but Supabase is faster to set up for authentication-centric apps. Hasura gives fine control over API permissions but expects deeper configuration.
Real-Time and Serverless Functionality
Supabase features built-in real-time database subscriptions, enabling use cases such as collaborative editing or live dashboards without extra configuration. Serverless functions are not publicly documented as core components.
Hasura’s documentation does not specify real-time or built-in serverless function support. It can enable subscriptions via GraphQL, but broader real-time features or serverless capabilities are not highlighted in the provided facts.
If your app depends on real-time updates, Supabase is likely the easier starting point.
Compliance and Data Protection
Neither product’s documentation contains public details about SOC 2 or GDPR compliance. Supabase enforces RLS at the database for granular data access, while Hasura uses permission rules for API-layer control. For projects in regulated industries, the lack of clear, public compliance details means you’ll need to contact vendors or plan for detailed security review before handling sensitive information.
Pricing Models and Usage Limits
Supabase offers a free tier with usage and data limits. As your project grows, paid plans unlock higher usage and larger resources. Specific free-tier quotas are not included in the provided data.
Hasura Cloud also includes a free tier, with metered usage and limitations. Upgrading is required if you exhaust these allocations. Both platforms thus allow trying out features at no cost, but scaling to production workloads may require budgeting for paid plans.
Choosing the Right Tool for Your Project
If your priority is rapid delivery and hosting with a full backend stack—managed Postgres, authentication, REST, and real-time APIs—Supabase is the logical choice. Its out-of-the-box functionality suits SaaS MVPs, web applications, and any team that prefers “batteries included.”
Hasura is optimal if you already have a PostgreSQL database and need a flexible, enterprise-grade GraphQL API. Its advanced query system and fine-grained permissions are valuable for apps demanding complex data access logic or working in an API-first architecture.
Choose based on your starting point: use Supabase for new projects needing hosted backend features, Hasura to modernize and API-enable existing data platforms.
Summary and Further Resources
Supabase excels as a Firebase alternative with managed database and built-in backend features. Hasura stands out for making advanced GraphQL APIs fast and flexible for any Postgres database. Review their free tiers for suitability, and validate compliance and real-time needs during your technical evaluation.

What are the main differences between Supabase and Hasura?
Supabase provides a full backend platform with managed Postgres, authentication, real-time, and REST/GraphQL APIs. Hasura is a GraphQL engine that connects to your existing PostgreSQL database to auto-generate APIs—hosting and authentication require your own solutions.
Which is better for GraphQL support, Supabase or Hasura?
Hasura is purpose-built for GraphQL, auto-generates a rich API, and offers advanced permissions. Supabase supports GraphQL but focuses more on REST, auth, and real-time capabilities.
How do Supabase and Hasura handle authentication and authorization?
Supabase has built-in authentication and uses RLS policies for data access. Hasura expects you to integrate your own authentication and applies granular permission rules over its APIs.
What are the pricing differences between Supabase and Hasura?
Both offer free tiers with usage limits. Supabase uses project-based plans; Hasura Cloud scales via metered usage and tiered plans. Exact quotas are not publicly listed in the evidence.
Which platform offers better scalability for production workloads?
Both are designed to scale, but actual production scalability depends on your team’s database management (for Hasura) or Supabase’s hosted Postgres limits. Details are not publicly specified.
How do Supabase and Hasura compare in terms of security and compliance?
Both provide granular, data-level access control (RLS in Supabase, permission rules in Hasura). Public compliance with SOC 2 or GDPR is not specified.
Which is easier to integrate with existing PostgreSQL databases?
Hasura is designed specifically to connect to and API-enable your existing Postgres database, making integration direct. Supabase hosts your database, making it best for greenfield projects.
