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, backed by a Durable Object with a built-in SQLite database, with input validation, error handling, and authentication checks.
Generated backends run on Cloudflare Workers at the edge. No servers to provision, patch, or scale. Pay only for what you use.
Tables and query logic for the app's built-in SQLite database are generated alongside your API. Relationships, indexes, and constraints are handled automatically, with no migration files.
Cookie session checks, CSRF protection, and role checks from the built-in auth protect your endpoints, and anonymous API requests are refused by default.
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 checks resolve the HttpOnly session cookie against the server-side session table and refuse cross-site writes. Database queries run against the Durable Object's built-in SQLite database from typed server code. 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.
Request Checks: cookie session verification, same-origin CSRF checks, request logging, CORS configuration, and input validation, with rate limiting added on request.
Data Access: typed queries against the Durable Object's built-in SQLite database through ctx.storage.sql, proper transaction handling, and query performance considerations.
