Design database schemas in Raltey
Raltey has a dedicated database schema canvas. Describe the system in chat, the AI agent drafts tables, primary keys, and relationships, and you can iterate or export SQL DDL.
Built for database schemas that ship.
- Draft a schema from a product or feature description.
- Add or split tables, rename columns, or change relationships through chat.
- Primary key, foreign key, and column-type UI built into the schema canvas.
- Export SQL DDL for PostgreSQL, MySQL, or SQLite.
- Real-time collaboration with live cursors, comments pinned to nodes, and version history with attribution.
