MySQL DDL Generator

VibeSchema generates runnable MySQL DDL - CREATE TABLE statements with constraints, foreign keys, indexes, and enums. Describe what you need in chat or paste existing DDL to iterate on.

Example

Here is a real example. The prompt:

Create a basic SaaS app with organizations, users, and projects. Users belong to organizations, projects belong to organizations.

VibeSchema generates the schema instantly:

CREATE TABLE `organizations` (
  `id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
  `name` VARCHAR(255) NOT NULL,
  `created_at` TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

CREATE TABLE `users` (
  `id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
  `organization_id` INT NOT NULL,
  `name` VARCHAR(255) NOT NULL,
  `email` VARCHAR(255) NOT NULL UNIQUE,
  `created_at` TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
  FOREIGN KEY (`organization_id`) REFERENCES `organizations`(`id`)
);

CREATE TABLE `projects` (
  `id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
  `organization_id` INT NOT NULL,
  `name` VARCHAR(255) NOT NULL,
  `description` TEXT,
  `created_at` TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
  FOREIGN KEY (`organization_id`) REFERENCES `organizations`(`id`)
);

The ER diagram updates live as the schema changes. Keep iterating in chat to add columns, constraints, or new tables.

Start from existing DDL

Already have a schema? Paste it into Code View and VibeSchema loads it as the starting point. From there you can ask the AI to restructure it, add tables, or tighten constraints — then export the updated DDL when done.

The AI reads and writes MySQL directly. There is no intermediate format and no conversion step, so constraints, defaults, and indexes are preserved exactly as written.
