Vibecode DB

Product Introduction

1. Vibecode DB is a frontend-first API gateway that enables applications to interact with diverse backend systems through a single unified interface. It allows developers to define their data schema once and execute queries across multiple database technologies without code modifications. The solution supports SQLite, Supabase, PostgreSQL, REST APIs, Firebase, GraphQL, and custom backends via its adapter architecture. This approach eliminates backend dependencies during frontend development while maintaining type safety throughout the data layer.

2. The core value lies in decoupling frontend development from backend constraints through its runtime-to-production workflow. Developers prototype instantly using local SQLite databases that simulate real backend services including authentication, storage, and functions. Teams seamlessly transition to production-grade databases like Supabase or PostgreSQL without rewriting application logic. This enables true "write once, use anywhere" flexibility while preventing vendor lock-in and reducing time-to-market for applications.

Main Features

1. The Unified Frontend API provides consistent query methods across all supported backends using JavaScript/TypeScript. Developers use identical syntax like .from('users').select('*').where('active', true) whether querying SQLite, Supabase, or REST APIs. This abstraction layer handles authentication protocols, data normalization, and error handling uniformly. TypeScript integration ensures compile-time validation of all queries against the predefined schema.

2. Runtime Data Adapters enable rapid prototyping with local database simulation. The SQLiteWebAdapter mimics backend services entirely in the browser, including relational operations, authentication flows, and file storage emulation. Developers can build complete application functionality without network dependencies or backend deployments. This adapter automatically synchronizes with the unified API interface used for production backends.

3. Backend Agnostic Architecture allows instant switching between database technologies via adapter configuration. The createClient() function accepts interchangeable adapters for Supabase, Firebase, GraphQL, or custom backends without code changes. CustomAdapter interface enables integration with proprietary systems or legacy APIs through standardized request/response patterns. All adapters implement consistent transaction handling, pagination, and real-time subscription models.

Problems Solved

1. The product eliminates development bottlenecks caused by backend-frontend dependencies during prototyping phases. Frontend teams no longer wait for API endpoints to be developed before building UI components and application logic. Runtime data simulation provides immediate feedback loops for data-driven features without mock implementations. This reduces typical development cycles by enabling parallel workstreams between frontend and backend teams.

2. Primary users include frontend developers working with React, Vue, Angular, or Next.js frameworks who need to iterate quickly on data-intensive applications. Full-stack developers building offline-capable applications benefit from the SQLite-to-cloud migration path. Engineering leads managing multi-backend environments gain standardization across PostgreSQL, Firebase, and legacy REST services through the unified gateway.

3. Typical scenarios include startups prototyping SaaS applications with local SQLite before migrating to Supabase for production. Enterprise teams modernizing legacy systems by creating adapter layers for existing REST APIs while maintaining existing frontend code. Cross-platform applications requiring offline-first capabilities with automatic cloud synchronization when connectivity resumes.

Unique Advantages

1. Unlike traditional BaaS solutions like Firebase or Supabase SDKs, Vibecode DB provides complete backend abstraction without binding applications to specific vendors. Whereas ORMs like Prisma only standardize database access, Vibecode DB extends unification to REST, GraphQL, and NoSQL systems through its adapter pattern. The solution differs from mock API tools by providing actual database functionality during prototyping that transitions to real backends without interface changes.

2. The runtime-to-production adapter system enables true "prototype with real data" workflows using fully functional local databases. CustomAdapter interface allows wrapping proprietary gRPC services, SOAP APIs, or legacy systems into the unified query interface. Type-safe schema enforcement works across all backend types, automatically validating queries against current data structures regardless of underlying technology.

3. Competitive advantages include zero rewrite requirements when scaling from prototype to production or switching database vendors. The open adapter system prevents ecosystem lock-in while supporting any existing or future backend technology. Development velocity increases by 3-5x through eliminated backend dependencies during early development phases. Teams maintain single codebase across web, mobile, and desktop platforms with automatic offline capability via SQLite integration.

Frequently Asked Questions (FAQ)

1. How does Vibecode DB handle database schema migrations between different backends? The system uses a centralized schema definition that automatically maps to each backend's native structure through adapters. When switching adapters, Vibecode DB validates compatibility and provides migration scripts for schema differences. Developers maintain one schema definition that synchronizes across SQL, NoSQL, and REST backends.

2. Can I use Vibecode DB with existing backend services without replacing them? Yes, the CustomAdapter interface allows wrapping existing REST, GraphQL, or gRPC endpoints into the unified API. The adapter translates Vibecode queries into native API calls while handling authentication and response normalization. This enables incremental adoption without disrupting current systems.

3. What happens to local SQLite data when switching to cloud backends like Supabase? The SQLiteWebAdapter includes optional synchronization mechanisms to seed production databases with prototype data. Migration utilities transfer schema and records to new backends during adapter configuration. Developers control whether to merge, replace, or archive runtime data during production transitions.

4. Does Vibecode DB support real-time subscriptions across all backend types? Yes, the unified API includes .subscribe() methods that work consistently across adapters. The SQLite adapter simulates real-time events through local emitters, while production adapters use native WebSockets (Supabase) or Cloud Firestore listeners (Firebase). All subscriptions follow identical event patterns regardless of backend.

5. How are authentication and authorization handled across different backends? Vibecode DB abstracts authentication through provider-agnostic auth() methods that work uniformly in prototype and production modes. Adapters translate these into backend-specific auth flows (JWT, OAuth, Magic Links). Row-level security policies are defined in the central schema and enforced by adapters through backend-native permission systems.
