OpenETL is a free, lightweight, and flexible ETL (Extract, Transform, Load) framework built in TypeScript, designed for developers who need a simple yet powerful tool to orchestrate data workflows in Node.js environments. With a modular architecture, OpenETL enables easy integration with various data sources and sinks—such as databases (e.g., PostgreSQL) and APIs (e.g., HubSpot)—through a consistent adapter-based approach.
- Type-Safe Configuration: Leverage TypeScript’s strong typing for defining connectors, transformations, and pipelines, reducing runtime errors and improving developer experience.
- Extensible Adapters: Easily connect to diverse systems with pre-built or custom adapters, supporting both download and upload operations.
- Data Transformation: Apply a variety of built-in transformations (e.g., renaming keys, concatenating fields) or extend with custom logic.
- Pipeline Orchestration: Define and execute data pipelines with configurable scheduling, error handling, and rate limiting.
- Lightweight Footprint: Minimal dependencies and a focus on simplicity make it ideal for small to medium-scale data projects or as a foundation for larger systems.
OpenETL is open-source under the MIT License, empowering developers to extract data, transform it efficiently, and load it into target systems—all within a single, cohesive framework. Whether you’re syncing CRM data, managing database migrations, or building custom ETL processes, OpenETL provides the tools to get the job done with minimal overhead.
