Visual Database Designer and Collaboration View

Feature Requests
1

As a Replit developer, I want a visual representation of my database so I can easily understand, validate, and collaborate on database design.

This would provide a shared, interactive diagram of tables and relationships, rather than requiring developers or stakeholders to read raw schemas or SQL.

Description
Replit should offer a built-in visual database designer that automatically reflects the current database structure and allows users to explore, edit, and discuss it visually.

Tables would appear as draggable cards, showing columns, types, and relationships. Changes to layout and annotations would persist, making the diagram a living part of the application, not a one-time export.

Core Capabilities

  • Visual Schema View

    • Tables displayed as cards with fields, data types, and relationships

    • Clear lines showing foreign key relationships

    • Zoom, pan, and search for large databases

  • Collaboration and Comments

    • Comment directly on tables, fields, or relationships

    • Add notes for design decisions or future changes

    • Collaborate with other developers in real time

  • Organization and Clarity

    • Color-code tables by domain (for example: Auth, Billing, Orders)

    • Group related tables into collapsible sub-groups

    • Drag and drop tables freely and save layout per project

  • Versioning and History

    • Track versions of the database diagram

    • View changes over time and understand how the data model evolved

    • Roll back to previous versions or compare designs

Extended Use Cases and Value

  • Faster Onboarding
    New developers can understand the system in minutes by exploring the diagram instead of digging through migrations or code.

  • Design Reviews and Planning
    Teams can review schema changes visually before implementation, reducing costly mistakes.

  • Non-Technical Stakeholder Alignment
    Product managers, designers, and business users can understand how data is structured without needing SQL knowledge.

  • Documentation That Stays Current
    The diagram stays in sync with the actual database, eliminating outdated docs and screenshots.

  • Safer Refactoring
    Developers can see downstream impacts before modifying or removing tables and fields.

  • AI-Assisted Opportunities (Future)

    • Ask Replit AI to explain a table or relationship in plain English

    • Get suggestions for normalization or performance improvements

    • Generate migrations from visual edits

Why This Matters
Databases are the foundation of every application, but they are often invisible or hard to reason about. A visual, collaborative database view would turn the data model into a first-class citizen in Replit, improving quality, communication, and confidence across teams.

Who This Helps

  • Solo developers building complex apps

  • Teams collaborating on shared data models

  • Agencies managing multiple client projects

  • Non-technical stakeholders who need clarity without complexity

this would be amazing, I second this. I don’t know how many people are building truly complex apps with large databases on here, I would be curious how development has gone for them especialy with complex databases.

Agreed! We’re actively trying to build more complex apps internally, with the longer-term goal of being able to confidently build and ship complex apps for clients once we’ve battle-tested the process ourselves.

Having this feature would be huge. The versioning piece especially, it’d be really helpful to see how the database evolves from prompt to prompt and what changes Replit is actually making along the way.
