The record

Purpose: sqldef is a CLI tool for diffing SQL schemas and managing RDBMS migrations with regular SQL DDLs.
Supported databases: The site lists MySQL, MariaDB, TiDB, PostgreSQL, SQL Server, and SQLite3 as supported databases.
Schema workflow: Users define a desired schema in SQL, and sqldef generates and applies migrations to bring the database to that state.
Idempotency: The README says sqldef operations are idempotent and safe to run multiple times.
Preview and offline modes: sqldef can preview migrations without executing them and compare SQL files without connecting to a database.
Rename support: The README says the @renamed annotation supports renaming tables, columns, indexes, and ENUM values.
Distribution: The project provides pre-built single-binary executables and Docker images.
Platforms: The releases page lists downloadable binaries for Windows, macOS (Darwin), and Linux.
Integrations: The README links to a GitHub Action that previews database schema changes.
Security and licensing: The README states that sqldef source files are distributed under the MIT License, except the parser, which is under Apache License 2.0.
Support: The project invites feature requests through pull requests or GitHub Discussions.
Linux package limitation: The README says Debian packages are not currently available and directs Linux users to pre-built binaries or Docker images.
Audience: The README describes a workflow for database schema changes that uses a single SQL file containing the complete schema.
Online demo: The official site says its online demo uses a WebAssembly build of sqldef to diff schemas and generate DDLs.
