What is Singer.io?
A simple guide to features, pros, and cons
Singer is an open-source ETL (Extract, Transform, Load) framework designed to move data between different tools, databases, and APIs with minimal complexity. It acts as a standard for building data pipelines, helping teams integrate data from multiple sources into a single destination efficiently.
Instead of using heavy platforms, Singer focuses on small, modular scripts that can be combined like building blocks.
