Melange v0.1.0 - Preview

The first pre-release of Melange, an OpenFGA-compatible authorization library that runs entirely in PostgreSQL.

What is Melange?

Melange takes a different approach to authorization. Instead of running graph traversal in application code, Melange:

• Precomputes authorization rules at migration time - OpenFGA schemas are parsed and flattened into PostgreSQL tables
• Executes permission checks in SQL - Runtime queries leverage precomputed data with no application-level graph traversal
• Uses views for tuple storage - Permissions derive from a melange_tuples view over your existing tables

Initial Features

• Core schema parsing and model generation
• Basic permission checking infrastructure
• PostgreSQL function-based authorization checks
