Atlas vs Evolve

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.

Evolve is a free, open-source database migration tool that applies plain SQL scripts to synchronize changes across environments and development teams, including continuous integration and delivery. It is available as a .NET library, .NET tool, or standalone CLI. Listed databases include PostgreSQL, SQL Server, SQLite, MySQL, MariaDB, Cassandra, and CockroachDB. Versioned migrations run once; repeatable migrations run again when their contents change. Evolve records migration names and checksums in a metadata table and checks them whenever it runs. Commands are migrate, erase, repair, and info. Each migration normally uses its own transaction, while TransactionMode can group scripts for commit or rollback. Cluster mode uses a session-level lock to coordinate nodes. The standalone CLI supports x64 Windows and Linux without external dependencies. The library requires .NET 4.7.2+ or .NET Standard 2.0/.NET 5.0; the tool requires .NET Core SDK 3.0 or later.
