YOUR BACKEND WORKSPACE

Build something reliable.

Describe what you want to build. Describe what your app needs. BackendDev will turn it into an API project you can run and learn from.

QUICK START

Build your project, step by step

01Choose a starterName your project and pick its language.
02Shape your APIEdit files yourself or ask AI for a proposal.
03Run and iterateRun checks locally, fix errors, then export.

BACKEND BASICS

What happens when someone uses your app?

A backend is the part of an app that receives requests, applies rules, stores information, and sends a response.

1 · Request

A phone or website asks for something, such as GET /products.

2 · Route and logic

Your backend chooses a route, checks the request, and decides what should happen.

3 · Data

The backend reads or changes records. Starters use temporary memory; real services need a database.

4 · Response

The backend returns a status and JSON, which the app can display.

BACKEND BUILDER · STEP 1 OF 2

What do you want to build?

Use everyday words. We’ll turn your idea into a starter plan and API.

This choice determines the generated source files and which local runtime BackendDev uses to build, test, and run your backend.
Your starter plan

Tell us your idea to see the first routes BackendDev will prepare.

Starter data is in memory and resets when your API stops. Hosting requires a deployment provider and configured environment variables.

What this file does

Select a file to see how it fits into a backend.

How a request travelsApp / browser→Route→Logic→Data→JSON response
Starter API routes

GET /health checks whether the service is running.

GET /items lists records · POST /items creates one · GET /items/1 reads one · DELETE /items/1 removes one.

Try your API

Run your project and try its local URL, or test a deployed URL. Browser calls need CORS enabled on the API.

Response status, time, and body will appear here.
AI proposal
Describe a change and review the proposed files before applying.
Live runner outputLocal only · stops when you press Stop backend
Choose Run API server to start your backend. The process stays on until you stop it.

Review generated files before applying them. Run only code you trust. Framework packages may need to be installed separately.
BEGINNER DEPLOYMENT CHECKLIST

Get your backend online

BackendDev creates and checks code. To host a live API, deploy your exported project on a hosting provider such as Render, then set its start command and environment variables.

  1. Choose a project and export its files.
  2. Create a web service in your hosting provider and connect your Git repository.
  3. Set a build/start command and required environment variables.
  4. Deploy, then paste the public URL into the API tester.
