Category: devtools

Tags: supabase, sql-linter, migrations, postgres, grants, ci

Score: 6.8/10 (Innovation: 6, Technical: 7, Documentation: 8, Utility: 6)

A linter that replays Supabase SQL migrations to detect missing table grants before the 2026-10-30 change where new tables no longer get automatic grants. It models privileges and policies without a database connection, reports fixes, and integrates with CI and eslint. The focus on a specific, upcoming breaking change makes it a targeted but useful tool for Supabase users.

Target audience: backend developers, devops, database administrators
