Serverless APIs and Business Logic from Text
Describe your API endpoints, data models, and business rules in plain English. Fabricate generates a complete serverless backend on Cloudflare Workers with D1 database integration, input validation, error handling, and authentication middleware.
Generated backends run on Cloudflare Workers at the edge. No servers to provision, patch, or scale. Pay only for what you use.
D1 database schemas, migrations, and query logic are generated alongside your API. Relationships, indexes, and constraints are handled automatically.
JWT validation, session management, and role-based access control are generated as reusable middleware that protects your endpoints.
Request and response types are defined in TypeScript. Input validation catches malformed data before your business logic runs.
Every API endpoint runs within 50ms of your users on Cloudflare's global network. No cold starts, no regional latency.
Generated backends follow a clean architecture: routes, controllers, services, and data access layers are properly separated.
Describe the endpoints you need: "A REST API for managing projects with CRUD operations and team member assignments."
Route handlers, database queries, validation schemas, and middleware are generated with proper error handling.
Your API runs in the preview environment. Test endpoints directly or connect your frontend to verify integration.
Describe complex rules: "When a task is marked complete, notify all team members and update the project progress percentage."
Deploy your backend to 300+ Cloudflare edge locations with a single click.
Building a backend API requires designing endpoint structure, implementing authentication middleware, validating request inputs, querying databases safely, handling errors consistently, and deploying to reliable infrastructure. Fabricate generates complete backend APIs as Cloudflare Workers with all of these handled correctly. API routes are typed and validated with Zod schemas. Auth middleware verifies the signed JWT session token and checks the session has not been revoked. Database queries use Drizzle ORM for type-safe access. Error responses follow consistent JSON structure. Rate limiting prevents abuse. The result is a production-ready API from the first deploy.
API Design: RESTful endpoint structure following resource-based naming. Consistent response envelopes, HTTP status codes, and error formats.
Middleware: signed JWT session verification, rate limiting with Cloudflare rate limiters, request logging, CORS configuration, and input validation.
Data Access: Type-safe D1 database queries via Drizzle ORM, proper transaction handling, connection pooling, and query performance considerations.
