Model your data. Simply.

Unify your conceptual, logical, and physical models in one collaborative tool.

Keep every layer connected

Outdated tools slow you down. Traditional modeling platforms are complex, siloed, and hard to collaborate in. Designs get lost between conceptual ideas, logical schema, and physical reality.

Modelly keeps every layer connected. Build once, refine deeper. With layers that inherit, you stay aligned from concept through to production SQL.

How it works

Transform your data modeling workflow with our layered approach that keeps everything connected.

Conceptual Layer

Start with high-level entities and relationships. Focus on the business logic without technical constraints.

Logical Layer

Refine your model with detailed attributes, data types, and relationships. Still database-agnostic.

Physical Layer

Generate production-ready schemas optimized for your specific database platform and requirements.
