Choosing the Right ORM for Your Go Project
Object-Relational Mappers (ORMs) are powerful tools that simplify interactions between your Go application and a SQL database. With so many ORMs available, selecting the right one for your project can be overwhelming. In this article, we’ll explore seven popular ORM packages in the Go ecosystem, their features, and use cases.
What is an ORM?
An ORM provides a layer of abstraction between your application’s code and the database, allowing you to interact with the database using your preferred programming language’s data types and syntax. This eliminates the need to write raw SQL queries, making it easier to switch between different databases and reducing development time.
Top 7 ORMs in Go
Here’s a brief overview of each ORM package:
- GORM: The most popular ORM in Go, GORM is a developer-friendly, feature-rich package that supports multiple databases, including MySQL, PostgreSQL, and SQLite.
- SQLC: An SQL compiler ORM that generates type-safe code from SQL queries, SQLC is ideal for those who prefer a schema-first approach.
- SQLX: A lightweight, extendable package that provides additional functionality on top of the standard
database/sqlpackage. - Beego: A powerful ORM inspired by popular Python ORMs, Beego is part of the Beego web framework and supports MySQL, PostgreSQL, and SQLite.
- GORP: While not strictly an ORM, GORP provides a way to interact with SQL databases using Go’s built-in data types, making it a popular choice for those who prefer a code-first approach.
- Go-firestorm: A fast, easy-to-use ORM designed specifically for Google Cloud Firestore, Go-firestorm is perfect for those working with this NoSQL database.
- SQLBoiler: A schema-first ORM that generates type-safe models from your database schema, SQLBoiler is ideal for those who prioritize performance and type safety.

| ORM | Approach | Supported Databases | Developer Experience | Popularity |
| — | — | — | — | — |
| GORM | Code-First | Multiple | Excellent | High |
| SQLC | Schema-First | Multiple | Good | Medium |
| SQLX | Lightweight | Multiple | Fair | Low |
| Beego | Code-First | Multiple | Excellent | High |
| GORP | Code-First | Multiple | Good | Medium |
| Go-firestorm | Code-First | Firestore | Excellent | Low |
| SQLBoiler | Schema-First | Multiple | Good | Medium |
Choosing the Right ORM for Your Project
When selecting an ORM, consider the following factors:
- Project size and complexity
- Preferred database and ORM approach
- Performance and type safety requirements
- Community support and documentation
Based on these factors, here are some recommendations:
- For most projects, GORM or Beego are excellent choices due to their popularity, ease of use, and extensive community support.
- If you prefer a schema-first approach, SQLC or SQLBoiler may be a better fit.
- For Google Cloud Firestore projects, Go-firestorm is the obvious choice.
- If you’re looking for a lightweight, extendable ORM, SQLX may be the way to go.
Ultimately, the choice of ORM depends on your specific project needs and personal preferences. By considering the factors mentioned above and exploring each ORM’s features and use cases, you’ll be able to make an informed decision and choose the best ORM for your Go project.
