njord
A versatile, feature-rich Rust ORM library for simplifying database interactions across multiple systems.
What is njord?
Njord is a versatile and feature-rich Object-Relational Mapping (ORM) library for Rust, designed to simplify database interactions across a wide range of systems with robust performance and flexibility. It provides a comprehensive toolkit for developers to manage database operations efficiently, supporting various databases and offering tools for migrations and machine learning workflows.
Rust developers building applications that require database interactions across multiple database systems, including SQLite, PostgreSQL, MySQL, MariaDB, Oracle, and MSSQL. It also targets developers working on machine learning pipelines who need integrated data handling capabilities.
Developers choose Njord for its broad multi-database support, allowing consistent ORM usage across different systems without sacrificing performance. Its planned machine learning integration (njord_ml) offers specialized tools for data extraction, transformation, and injection in ML workflows, setting it apart from traditional ORMs.

A versatile, feature-rich Rust ORM ⛵
Use Cases
Best For
- Building Rust applications that need to support multiple database backends (SQLite, PostgreSQL, MySQL, MariaDB, Oracle, MSSQL) with a single ORM.
- Developing machine learning pipelines in Rust that require efficient data handling, extraction, transformation, and injection from databases.
- Projects requiring raw SQL execution alongside ORM abstractions for advanced database interactions.
- Teams planning to implement database migrations in Rust, though the CLI tool is currently in development.
- Applications where database transaction support is needed, with varying implementation levels across supported databases.
- Systems that benefit from JOIN operations across supported databases like SQLite, MySQL, MariaDB, Oracle, and MSSQL.
Not Ideal For
- Projects requiring immediate, full-featured PostgreSQL ORM support (JOIN, SELECT, etc., are under construction)
- Teams needing a production-ready migrations CLI tool for schema management (currently paused with no database support)
- Applications dependent on stable transaction support across all databases (transactions are marked as under construction for most)
- Machine learning workflows requiring integrated data tools today (njord_ml is only on the roadmap, not implemented)
Pros & Cons
Pros
Supports SQLite, PostgreSQL, MySQL, MariaDB, Oracle, and MSSQL, with CRUD operations for most, as shown in the feature support table, enabling consistent ORM usage across systems.
Allows execution of raw SQL queries for advanced interactions, supported across all databases except some pending features, per the README's feature table.
Plans for njord_ml library to handle data extraction, transformation, and injection for ML pipelines, with a detailed feature roadmap outlined in the README.
Has multiple contributors listed, indicating ongoing development and community involvement, as seen in the contributors section.
Cons
Many key features like JOIN for PostgreSQL and transactions for most databases are marked as under construction (🏗), limiting functionality for certain use cases.
The migrations CLI is paused with no database support yet, making schema management reliant on external tools or manual work, as admitted in the README.
The machine learning integration is only a roadmap with no implemented features, so it's not usable for current projects, requiring separate data handling solutions.
