Generate a complete backend with AI.

Zusagi is an AI backend generator. It designs your data model, creates APIs and authentication, and connects everything to the frontend it built, so you never assemble a backend by hand.

Start building How it works

Zusagi generating backend services for an app

APIs, auth and data, generated to match your frontend.

REST APIs

Endpoints for every feature your screens need, with validation and error handling.

Authentication

Sign-up, login, sessions, roles and password reset.

Database schema

Tables, relations and migrations designed from your description.

Business logic

Server-side rules, jobs and workflows written as readable code.

Integrations

Payments, email, storage and third-party APIs connected on request.

Deployment

Backend deployed together with the frontend on Pro and Max plans.

Workflow

A backend that fits the app, not the other way round.

Because Zusagi plans frontend and backend together, the API matches what the screens actually call.

Describe the features
For example: users, teams, invoices and a monthly report.
Review the data model
Zusagi proposes entities, relations and endpoints. Adjust in plain language.
Generate and test
APIs and auth are generated and exercised by the frontend preview.
Fix and deploy
Describe any issue; Zusagi patches the code. Deploy when ready.

Backend generator FAQ

Can Zusagi build a backend without a computer?

Yes. Backend generation, testing and deployment all happen from your phone.

Does Zusagi create the database too?

Yes. The schema is generated with the backend and connected to your APIs.

Can I use the backend with an existing frontend?

Zusagi is designed to generate the full stack together; generated APIs can also be consumed by other clients.
