overview

What is Kestra?

Kestra is an orchestration tool developed by Kestra (company) that enables engineers and business users to automate processes across data, AI, and infrastructure domains. It supports both code-based definitions, emphasizing a YAML-first and 'everything as code' approach, and UI-driven workflow creation. The platform operates as an event-driven system with a plugin ecosystem and offers built-in agentic automation. Kestra supports multiple languages for workflow definitions, catering to data, software, and platform engineers seeking to manage complex automation tasks. Its core purpose is to streamline automation across various domains, including ETL/ELT processes, model training, infrastructure provisioning, and microservice management. Kestra is designed for cloud-native environments and distributed architectures, enabling automatic scaling for large-scale workflows and massively parallel tasks.

how to use

How to Use Kestra

Kestra workflows are primarily defined using YAML files, which can be managed through version control systems or created directly within the platform's user interface. The platform executes these workflows in an event-driven manner, responding to various triggers.

  • 1Define workflows using YAML files, specifying tasks, triggers, and dependencies.
  • 2Utilize the Kestra UI to visually build, monitor, and debug workflows.
  • 3Integrate with external systems and services using Kestra's extensive plugin ecosystem.
  • 4Configure event-driven triggers such as file arrivals, API calls, or messages from queues (e.g., Kafka, AWS SQS).
  • 5Deploy Kestra in cloud-native environments for scalable and distributed execution.
  • 6Monitor workflow executions, view detailed logs, and analyze metrics for performance and troubleshooting.

Kestra vs Competitors

Kestra distinguishes itself in the workflow orchestration landscape through its declarative YAML-first approach, event-driven architecture, and broad applicability across data, AI, and infrastructure. While competitors often specialize or rely on specific programming languages, Kestra offers a more language-agnostic and unified platform.

1
Apache AirflowOn Stork

Widely adopted, Python-native for defining Directed Acyclic Graphs (DAGs), with an extensive community and integrations.

Airflow primarily uses Python for workflow definitions, which differs from Kestra's YAML-first and multi-language approach; its event-driven capabilities are less native than Kestra's, often requiring external triggers.

2
PrefectOn Stork

Focuses on dataflow automation with a strong emphasis on robust, observable, and resilient pipelines, primarily using Python.

Prefect is heavily Python-centric, which might be a limitation for users seeking multi-language or YAML-first definitions like Kestra; Kestra's built-in agentic automation and broader scope for infrastructure tasks might offer more flexibility outside of pure data workflows.

3
DagsterOn Stork

Designed specifically for data assets and MLOps, providing a unified programming model for defining, testing, and observing data pipelines.

Dagster is more opinionated towards data assets and MLOps, which might be overkill for general-purpose automation compared to Kestra's broader 'data, AI, and infrastructure' scope; Kestra's YAML-first approach and multi-language support offer a different paradigm for workflow definition.

4
Argo WorkflowsOn Stork

Natively runs on Kubernetes, defining workflows as YAML manifests for container-native orchestration.

Argo Workflows is tightly coupled with Kubernetes, which is a prerequisite, unlike Kestra which can run in various environments; Kestra offers a more abstracted, platform-agnostic approach to workflow definition and execution, potentially simplifying deployment for non-Kubernetes users.
