SchemaForge v1.7.0: VS Code Extension + 11-Format Bidirectional ORM Conversion

SchemaForge now supports 11 schema formats with 100 conversion directions (Alembic export only) — and a full VS Code extension with live preview, quick convert (Ctrl+Alt+S), format detection (Ctrl+Alt+D), and two-file diff. All tested, review conversion limitations.

What's New in v1.7.0

This is our biggest release. We've expanded from 6 to 11 supported formats, shipped a complete VS Code extension, and added roundtrip checks for supported schema elements.

🧩

11 Formats

SQL DDL, Prisma, Drizzle, TypeORM, Django, SQLAlchemy, GraphQL SDL, JSON Schema, EF Core, Scala, Alembic

🔄

100 Conversion Directions

Alembic is export only; the other ten formats support import and export. Prisma → Django? Done. SQL DDL → Drizzle? Done. Check each output; foreign keys and ORM relationships are not preserved.

VS Code Extension

Live preview panel, quick convert (Ctrl+Alt+S), format detection (Ctrl+Alt+D), two-file diff, right-click context menu, custom .schemaforge editor

🧪

Review Every Conversion

Compare your converted schema with the original. Foreign keys and ORM relationships are not preserved by the current shared IR.

The Full Format List

Format	File Extension	Language
SQL DDL	.sql	SQL (universal)
Prisma	.prisma	TypeScript / Prisma
Drizzle ORM	.ts	TypeScript
TypeORM	.ts (decorators)	TypeScript
Django	models.py	Python
SQLAlchemy	models.py	Python
GraphQL SDL	.graphql	GraphQL
JSON Schema	.json	JSON
Alembic (export only)	.py	Python
EF Core	.cs	C#
Scala	.scala	Scala

VS Code Extension Features

The extension turns VS Code into a schema conversion workspace:

Live Preview Panel — Open a schema file and see the converted output in a side panel. Changes update in real-time.
Quick Convert — Press Ctrl+Alt+S to convert the active file. Extension detects the source format and prompts for the target.
Format Detection — Ctrl+Alt+D auto-detects the schema format of the current file (Prisma, Drizzle, SQL DDL, etc.).
Two-File Diff — Compare two schema files side-by-side, regardless of format.
Context Menu — Right-click any schema file and select "SchemaForge: Convert..."
Custom Editor — Files with .schemaforge extension open in a dedicated editor with format-paired conversion.

Quick Start

Install the CLI:

pip install git+https://github.com/Coding-Dev-Tools/schemaforge.git

Convert a Prisma schema to SQLAlchemy models:

schemaforge convert schema.prisma --from prisma --to sqlalchemy

Convert SQL DDL to Drizzle TypeScript:

schemaforge convert schema.sql --from sql --to drizzle

Convert Django models to TypeORM:

schemaforge convert models.py --from django --to typeorm

Roundtrip Verification and Current Limits

Review the converted output and compare a roundtrip before using it in a migration. Current capabilities and limitations include:

Constraints — Supported primary keys, unique constraints, nullability, and defaults; inspect format-specific output
Indexes — Supported index definitions; review format-specific output
Relations — Foreign keys and ORM relationships are not modeled by the current IR and are dropped during conversion
Enums and custom types — Schema-specific type mappings
Roundtrip fidelity — Convert A→B→A and inspect the diff; this is a check, not a guarantee of lossless conversion

Why SchemaForge?

Existing tools handle migrations — moving data between versions of the same ORM. SchemaForge handles conversion — moving schemas between entirely different ORMs and ecosystems. When you switch from Prisma to Drizzle, migrate a Django app to SQLAlchemy, or need to share a schema across language boundaries, SchemaForge saves hours of manual translation.

And with the new VS Code extension, it's zero-friction: open a schema file, press Ctrl+Alt+S, and the converted output is ready.
