InstantDB Backend Choice

​
Context

Hotpot Tracker requires a real-time, collaborative backend solution that supports:
  • Team-based task management with boards and columns
  • Real-time updates for collaborative work environments
  • User authentication and team memberships
  • Complex relational data structures
  • Offline-first capabilities
The team has strong React/TypeScript skills but limited backend expertise. We need a solution that minimizes backend development while providing enterprise-grade features for collaborative task management. Alternatives considered:
  • Firebase: Limited relational capabilities, complex real-time queries
  • Supabase: More setup overhead, requires managing PostgreSQL
  • Custom Node.js API: High development and maintenance overhead

​
Decision

We will use InstantDB as our primary backend-as-a-service (BaaS) solution. InstantDB provides:
  • Built-in real-time synchronization and multiplayer features
  • Native support for complex entity relationships
  • Schema-first approach with TypeScript integration
  • Magic link authentication with minimal setup
  • Optimistic updates and offline-first capabilities

​
Consequences

​
What becomes easier:

  • Rapid development with minimal backend code required
  • Real-time collaboration features work out-of-the-box
  • Schema evolution managed through structured migrations
  • Strong TypeScript integration improves developer experience
  • Authentication and user management handled automatically
  • Offline functionality requires no additional implementation

​
What becomes more difficult:

  • Vendor lock-in to InstantDB ecosystem increases migration costs
  • Less control over backend logic compared to custom solutions
  • Potential scaling limitations with complex business logic
  • Learning curve for InstantDB-specific patterns and limitations
  • Limited customization options for advanced use cases
  • Dependency on third-party service for critical application functionality
