Atlas vs Doctrine Migrations

Atlas is a language-independent tool for managing database schemas and migrations through declarative, versioned workflows. It compares a database's current state with a desired schema expressed in HCL, SQL, or an ORM format, then can generate and execute a migration plan. Teams can lint and validate migrations, run safety checks, and test schemas and migrations. The open version supports PostgreSQL, MySQL, MariaDB, SQLite, TiDB, and LibSQL; Pro adds drivers including SQL Server, Oracle, Snowflake, and Databricks. Atlas describes its core engine as open source under Apache 2.0, with advanced features in proprietary versions. Integrations include Kubernetes, Terraform, GitHub Actions, GitLab CI, CircleCI, Bitbucket Pipelines, Azure DevOps, and a Go SDK. Starter is free. Atlas Pro costs $9 per developer per month, plus usage-based pricing for CI/CD pipelines and databases; new users can try Pro for 30 days. Schema Monitoring costs $39 per monitored database per month. Enterprise pricing is custom.

Doctrine Migrations is a free, self-hosted PHP library for versioning database schemas and deploying changes in a reviewable, testable way. Built on Doctrine DBAL and ORM, it can generate migration code by comparing a database schema with ORM mapping information, with documentation covering diffing with or without the ORM. Console commands show migration status, perform dry runs, execute one or more migrations, and revert changes. Generated SQL can be written to a file with --write-sql instead of applied directly, while --no-interaction supports unattended execution. Transaction controls cover all-or-nothing behavior and running with or without transactions. Install it through Composer, which provides a doctrine-migrations console application, or download a PHAR from GitHub releases. Doctrine lists integrations for Symfony, Zend, Laravel, Silex, and Nette. Version 3.9.8 is stable; 3.8 and earlier are unmaintained.
