Kestra

The platform provides an event‑driven, language‑agnostic environment for defining, scheduling, and monitoring workflows as code. Users create workflows in a declarative YAML format, either through a built‑in editor or via UI, and can trigger them on a schedule or in response to real‑time events. It supports Git integration for version control, allowing CI/CD pipelines to manage workflow definitions alongside application code.

A rich plugin ecosystem supplies connectors for databases, cloud storage, APIs, and the ability to run scripts in any language, enabling data pipelines, ETL/ELT processes, infrastructure automation, and AI tasks to be orchestrated from a single system. Features such as namespaces, retries, timeouts, error handling, and conditional branching provide resilience and fine‑grained control.

The software is self‑hosted, open source under Apache‑2.0, and designed for enterprise‑scale reliability with high availability, fault tolerance, and the capacity to handle millions of workflows. It targets teams that need a unified, code‑first orchestration solution across data, AI, and infrastructure domains.
