Why Sepio?

Sepio is a visual-first, Figma-like database design tool for developers. It enables smart schema modeling with built-in linting, architectural recommendations, version history, real-time multiplayer collaboration, and instant link sharing. The goal was to build a visually clean, comfortable interface without compromising on the powerful features modern engineering teams need.

Frequently asked questions.

Can I import an existing database or SQL file to generate a diagram?
Yes! You can paste raw SQL CREATE TABLE DDL statements or DBML scripts directly into Sepio to auto-generate visual ERD diagrams in seconds. You can also connect via live connection string introspection to reverse-engineer PostgreSQL and MySQL databases.
How does Sepio compare to tools like DrawSQL, dbdiagram.io, or Eraser?
Sepio combines the visual drag-and-drop canvas experience of Figma and DrawSQL with the fast code generation of dbdiagram.io. Plus, Sepio adds real-time schema linting, native Drizzle ORM TypeScript code generation, offline PWA support, and live team multiplayer collaboration.
Are there limits on the number of tables or diagrams I can create?
No hidden limits! You can create unlimited ERD diagrams and model as many tables as you need locally in your browser.
What code formats can I export my ERD diagram to?
Sepio exports to type-safe Drizzle ORM TypeScript (pgTable, mysqlTable, sqliteTable), raw PostgreSQL, MySQL, and SQLite DDL scripts, DBML, Prisma schemas, as well as vector SVG and high-resolution PNG diagrams.
Do I need to create an account or sign in to use Sepio?
No. You can start designing database schemas instantly without an account — your work is saved locally in your browser. Signing in is optional to unlock cloud backup, cross-device sync, team multiplayer, and shareable web links.
How does real-time team collaboration work?
When signed in, you can invite team members to your workspace to design schemas together simultaneously with live cursor presence, instant updates, version history, and shareable view/edit links.
Is my database schema data private and secure?
Yes. Unauthenticated work stays 100% local on your machine inside browser storage. When you sign in for cloud sync or multiplayer, data is encrypted both in transit and at rest. We never sell your data or train AI models on your schema architecture.
