## What it is
Atlas is a language-agnostic CLI tool for managing and migrating database schemas as code, supporting declarative (Terraform-like) and versioned migration workflows. It supports many databases (PostgreSQL, MySQL, SQLite, SQL Server, ClickHouse, and more) and integrates with ORMs, CI/CD systems, Kubernetes, and Terraform.

## Use cases
- generate sql migrations from schema changes
- apply database schema migrations in ci/cd
- manage database schema as code like terraform
- lint and review migration files before applying
- detect schema drift between environments
- run database migrations on kubernetes with gitops
- migrate postgres schema from orm models
- manage migrations for multiple databases in one tool

## When to choose
- you want automated migration planning instead of hand-writing ALTER statements
- you need schema-as-code workflows with review, linting, and CI/CD integration
- you manage schemas across many database engines and want one tool
- you want GitOps or Terraform-based database schema management

## When to avoid
- you only need a tiny embedded migration runner inside a single-language app
- your database engine is not among the supported ones
- you prefer hand-written, fully manual SQL migration files without tooling
