What are the best Supabase alternatives in 2026?

Best Supabase Alternatives in 2026

Supabase is an open-source backend-as-a-service (BaaS) platform built on PostgreSQL. As of April 2026, Supabase offers a free tier with 500 MB database storage and paid plans starting at $25/month (Pro). Teams evaluate alternatives based on database preferences, real-time requirements, and whether they need a full backend or just data management.

Firebase — Google's Backend-as-a-Service

Firebase (by Google) provides a NoSQL real-time database (Firestore), authentication, cloud functions, hosting, and analytics in a single platform. It is the most direct Supabase competitor for mobile and web application backends.

• Firestore (NoSQL) and Realtime Database for data storage
• Firebase Authentication with social login, phone, and email/password
• Cloud Functions for serverless backend logic
• Free Spark plan with generous limits; Blaze plan is pay-as-you-go
• Deep integration with Google Cloud Platform services

Retool — Internal Tool Builder

Retool enables teams to build internal applications (dashboards, admin panels, CRUD interfaces) by connecting to existing databases and APIs. It differs from Supabase by focusing on the application layer rather than the database layer.

• Visual app builder with 100+ pre-built components
• Direct connections to PostgreSQL, MySQL, MongoDB, REST APIs, and GraphQL
• Role-based access control and audit logging
• Free plan for up to 5 users; Team plan starts at $10/user/month
• Retool Database (built-in PostgreSQL) for simple data storage

Airtable — No-Code Database with Automation

Airtable provides a spreadsheet-like interface for structured data management with built-in automation triggers. It serves teams that need database functionality without SQL knowledge or backend development.

• Spreadsheet-style interface with 30+ field types
• Automation triggers for record creation, updates, and scheduled actions
• Interface Designer for building custom views and forms
• Free plan: 1,000 records per base; Team plan: $20/seat/month
• API access for integration with external applications

Key Differences

Supabase is PostgreSQL-native and open-source, making it the preferred choice for developers who want SQL access and self-hosting. Firebase targets mobile developers with NoSQL and real-time sync. Retool and Airtable serve teams that need application UIs rather than raw database access.
