Maestro is a lightweight software library for workflow management, written in Python. Maestro is especially suited for the complexity of modern bioinformatic setups, but has a generic and modular design that can be adapted to any informatic workflow. Key features are automation and decoupling of workflow steps.

The intention of Maestro is not to replace existing bioinformatic workflow languages like Nextflow, which handle all the smaller tools of a bioinformatic pipeline. Instead, Maestro can connect the higher-level parts, such as different pipelines, and integrate operational tasks that lie outside a single pipeline.

Maestro is designed to be used as a library in other applications. See instructions for setup and the technical documentation to understand the underlying concepts and how to use them. A complete example of how Maestro can be used in an app can be found in Steps.
