satus demo—generate seed data in your browser

§01|Try it

paste a schema. get real rows. nothing to install.

This page runs real Postgres (compiled to WASM) in your browser. Your DDL never leaves the tab — only column names and types are sent to our server for the one model call, on our API bill. Capped at 5 rows across 6 tables; the CLI has no such caps and runs against your own database with your own key.

create type order_status as enum ('pending','paid','fulfilled','refunded');

create table customers (
  id uuid primary key default gen_random_uuid(),
  email text not null unique,
  full_name text not null,
  country char(2) not null
);

create table categories (
  id serial primary key,
  name text not null unique,
  featured_product_id int  -- cycle: closed after products exists
);

create table products (
  id serial primary key,
  category_id int not null references categories(id),
  sku text not null unique,
  name text not null,
  price_usd numeric(8,2) not null check (price_usd > 0)
);

alter table categories add constraint categories_featured_fk
  foreign key (featured_product_id) references products(id);

create table orders (
  id bigserial primary key,
  customer_id uuid not null references customers(id),
  status order_status not null default 'pending',
  total_usd numeric(10,2) not null
);

create table order_items (
  id bigserial primary key,
  order_id bigint not null references orders(id),
  product_id int not null references products(id),
  qty int not null check (qty between 1 and 20),
  unit_price_usd numeric(8,2) not null
);

§02|Results

what actually landed.

Run the demo above. You’ll see the FK-dependency order satus derived, any cycle it broke, and the rows Postgres accepted — including anything it rejected, shown honestly.

§03|Demo vs CLI

what the demo skips.

The demo is the toy version: 5 rows, 6 tables, one shared rate-limited key, and no partitioned-table handling. The CLI introspects your live database, handles partitions and deferrable constraints, wraps every run in a single transaction with a --max-cost budget, and validates offline with --dry-run. Install it with npm i -g @passkeybridge/satus — the free tier needs no signup.
