Kestra

Declarative, event-driven orchestration for data and workflows at scale.

Kestra is an open-source orchestration and scheduling platform that lets teams build declarative, event-driven workflows in YAML with a rich UI on top. It targets data pipelines, infrastructure automation, and microservice orchestration, with hundreds of plugins, language-agnostic task execution, and built-in API and webhook triggers. It is designed to scale from simple cron jobs to complex distributed workflows.
