migrate
A database migration tool and library for Go, supporting multiple databases and sources via CLI or programmatic API.
What is migrate?
Migrate is a database schema migration tool and library written in Go. It manages the application of incremental, versioned changes to a database schema, solving the problem of tracking and deploying database changes reliably across different environments (development, staging, production). It reads migration files from various sources and applies them in the correct order to a target database.
Go developers and DevOps engineers who need a reliable, programmatic way to manage database schema changes for applications using PostgreSQL, MySQL, SQLite, MongoDB, or other supported databases.
Developers choose Migrate for its extensive database and source driver support, its dual nature as both a CLI tool and an importable library, and its robust design focused on preventing corruption and handling operations gracefully.
Overview
Database migrations. CLI and Golang library.
Use Cases
Best For
- Managing schema changes in Go applications with version-controlled migrations
- Applying database updates in CI/CD pipelines using a CLI tool
- Projects using multiple database types (SQL and NoSQL) that need a unified migration tool
- Teams needing to embed migration logic directly into their Go application binary
- Self-hosting applications that require reliable database state management during deployments
- Rolling back database changes safely after a failed deployment or bug
Not Ideal For
- Teams using non-Go languages who prefer migration tools native to their stack (e.g., Django Migrations for Python, Liquibase for Java)
- Developers needing a graphical interface to visualize migration history or manage changes interactively
- Projects requiring built-in data seeding, fixture management, or complex data transformations alongside schema migrations
- Environments where database connection strings frequently contain special characters, making manual URL escaping a recurring hassle
Pros & Cons
Pros
Supports a wide range of databases including PostgreSQL, MySQL, MongoDB, and CockroachDB via a driver-based architecture, allowing unified migrations across SQL and NoSQL systems.
Reads migrations from filesystems, embedded binaries (e.g., go-bindata), and remote sources like GitHub and AWS S3, offering versatility for different deployment workflows.
Can be used as a standalone CLI for scripting or imported as a Go library for embedding migrations directly into applications, as shown in the README code examples.
Handles interrupts gracefully (SIGINT) and is designed to prevent database corruption with thread-safe operations, emphasizing reliability in production.
Cons
Database URLs require manual escaping of special characters, which the README highlights with Python snippets, adding configuration overhead and potential for errors.
Primarily tailored for Go ecosystems, making integration less seamless for teams using other languages without additional wrappers or effort.
Some drivers, like SQLite3, are marked with 'todo' issues in the README, indicating potential instability or incomplete features for certain databases.
