Plan schema before migration

Design database schemas before they become production debt

Eflow is a visual ERD workspace for shaping tables, relationships, DBML, and SQL exports while your product is still changing fast.

Launch notes

Core capabilities available in this launch phase.

The first release focuses on the schema planning flow teams need before tables and relationships become production decisions.

Launch notes

v0.1

A focused first version for visual schema planning.

Map your database shape, inspect it as DBML, and export a SQL draft when the model is clear enough to become migration work.

Why it exists

Most schema mistakes start before the first migration.

Eflow is built for the planning window where the product is still moving, the database shape is still negotiable, and everyone needs a shared picture of what is being designed.

01

Relationships drift

Foreign keys, optionality, and many-to-many joins often get decided in a rush. Eflow gives those decisions a visible place before code locks them in.

02

DDL gets hard to review

Raw SQL is precise, but it is not always the fastest way for a team to understand whether the model makes sense.

03

Context disappears

A schema is more than tables. Notes, checkpoints, and workspace context help keep the reasoning close to the structure.

Features

A focused workspace for schema thinking

Eflow helps you move from rough database ideas to readable relational models without pretending to be a full enterprise platform on day one.

Visual schema canvas
Arrange tables, notes, and relationships in one focused workspace before the schema hardens into migrations.
SQL import and export
Bring existing DDL into the canvas, then export a readable SQL draft when the model is ready.
Relationship-first modeling
Use explicit cardinality tools for 1:1, 1:n, optional, and many-to-many relationship thinking.
Schema checkpoints
Save important modeling moments before a risky change, then compare and generate migration drafts.
DBML workflow
Move between visual structure and DBML when text is the faster way to inspect or refine a model.
Workspace context
Keep models grouped by workspace so schema design stays close to the product area it supports.
Open roadmap

Clear about what ships today.

This is a new launch, so the roadmap is part of the product story. Real capabilities are separated from active work and planned bets.
