Database schema generator

Describe your app or list your data in plain English, and get a starter Postgres schema — tables, sensible columns and the foreign keys between them — as ready-to-copy CREATE TABLE SQL. A fast way to sketch the data model behind your idea.

Describe your app or list your data

schema.sql · Postgres
CREATE TABLE users (
  id BIGSERIAL PRIMARY KEY,
  name text,
  email text UNIQUE,
  password_hash text,
  role text,
  created_at timestamptz NOT NULL DEFAULT now()
);

CREATE TABLE products (
  id BIGSERIAL PRIMARY KEY,
  name text,
  description text,
  price numeric(10,2),
  stock integer,
  sku text,
  created_at timestamptz NOT NULL DEFAULT now()
);

CREATE TABLE orders (
  id BIGSERIAL PRIMARY KEY,
  user_id BIGINT REFERENCES users(id),
  status text,
  total numeric(10,2),
  placed_at timestamptz,
  created_at timestamptz NOT NULL DEFAULT now()
);

CREATE TABLE payments (
  id BIGSERIAL PRIMARY KEY,
  order_id BIGINT REFERENCES orders(id),
  amount numeric(10,2),
  method text,
  status text,
  reference text,
  created_at timestamptz NOT NULL DEFAULT now()
);

CREATE TABLE order_items (
  id BIGSERIAL PRIMARY KEY,
  order_id BIGINT REFERENCES orders(id),
  product_id BIGINT REFERENCES products(id),
  quantity integer,
  unit_price numeric(10,2),
  created_at timestamptz NOT NULL DEFAULT now()

Want the app around this schema — not just the SQL?

Kashvi turns the same description into a real, working app: this database, plus the screens, logins and code — from one prompt. You own all of it.

A rule-based starting point for common entities — review types, indexes and constraints before using in production.

How it works

The generator recognises common entities in your description — users, products, orders, bookings, invoices, posts and more — and builds a table for each, with typical columns and an auto-incrementing primary key. When two entities are related, it adds the foreign key for you: an order gets a user_id, an order item points at both the order and the product. It is a rule-based starting point, so you stay in control of the final types and constraints.

Why start with the schema

The data model is the backbone of any real app. Getting the tables and relationships roughly right early saves painful migrations later — and it makes the rest of the build (the screens, the logins, the API) far more predictable.

This gives you the schema. Kashvi gives you the whole app around it — the same description becomes a real database plus the screens, logins and code, from one prompt.

Frequently asked

What does the database schema generator do?
It turns a plain-English description or a list of entities into a starter Postgres schema — CREATE TABLE statements with sensible columns, primary keys, timestamps and the foreign keys between related tables.
Is the generated SQL production-ready?
Treat it as a solid starting point. It gets the tables and relationships right for common cases, but you should review column types, add indexes, and tighten constraints for your specific needs before shipping.
Which database does it target?
PostgreSQL. The output uses Postgres types and syntax (BIGSERIAL primary keys, timestamptz, REFERENCES), which is exactly the database Kashvi provisions for the apps it builds.
Can it design my whole app, not just the schema?
The tool stops at the schema. Kashvi takes the same description and builds the real app — this database plus the working screens, authentication and code you own — from one prompt.
Do I need to sign up to use it?
No. It runs entirely in your browser, instantly, with no signup and nothing sent to a server.
