Orchestrate data, AI, and infrastructure workflows in YAML or UI without locking your team into a managed cloud orchestrator.
Kestra gives data teams one place to schedule ETL jobs, react to upstream events, run SQL or script tasks, and inspect failures without splitting work across cron, CI, and cloud-native schedulers.
Skip if your team only needs a single managed ETL connector service and does not want to run its own orchestrator.
Teams can use the same orchestration layer for provisioning steps, deployment automations, retries, error handling, and notifications, while keeping workflows in Git and reviewing them like code.
Skip if all orchestration must stay inside one cloud provider's managed control plane with no self-hosted component.
Kestra fits workloads that mix schedules with event triggers, such as model retraining, file arrival pipelines, webhook-driven jobs, and multi-step analytics workflows that need observability.
Skip if your jobs are simple single-step scripts with no dependency graph, retries, or audit needs.
Workflow automation breaks down when schedules, event triggers, scripts, SQL, and cloud tasks live in separate tools. Teams end up stitching together cron jobs, CI pipelines, Airflow DAGs, cloud-native workflow services, and custom scripts, then lose visibility when failures happen or when handoffs move across environments.
The cost is not only operational sprawl. Managed services such as AWS Step Functions, Azure Data Factory, and Google Cloud Composer can tie orchestration logic to one cloud stack, one billing model, or one deployment pattern. That makes it harder to keep workflows in Git, reuse the same orchestration model across data and infrastructure tasks, or run the platform in regulated and self-hosted environments.
Define flows in YAML and keep them in version control even when teammates edit from the UI. Kestra automatically writes workflow changes back to the declarative definition, which keeps CI/CD and review workflows intact.
Run cron-style jobs and real-time automations in the same platform through trigger definitions. Kestra is built around both scheduled and event-driven execution, so one flow model can cover batch pipelines, webhooks, and message-driven work.
Hundreds of built-in plugins let teams query databases, call APIs, move files, and run scripts in Python, Node.js, R, Go, shell, and other runtimes. That reduces the need for custom operators just to integrate common infrastructure.
Build and inspect flows in the UI with code editing, syntax validation, auto-completion, and a live DAG-style topology view. Non-specialists can review workflows without taking ownership away from engineers.
Start locally with Docker, then move to Docker Compose, Kubernetes, or public cloud templates as volume grows. Kestra documents high-availability and fault-tolerant operation for teams running large workflow estates.
Kestra is the better fit when teams want declarative YAML workflows, a built-in UI, event-driven triggers, and orchestration across data, AI, infrastructure, and business operations. Airflow remains stronger for organizations with mature DAG-heavy data platforms and a deep operator ecosystem. Choose Kestra for broader automation standardization; choose Airflow when established data engineering patterns are the main requirement.

kestra/kestra:latest server localYes. Kestra documents local Docker, Docker Compose, Kubernetes, and cloud deployment paths, so you can run it on your own infrastructure instead of relying on a hosted control plane.
No. The project positions itself for data, AI, and infrastructure workflows, with plugins and scripting support that let teams orchestrate APIs, scripts, cloud operations, and event-driven automations alongside ETL work.
Kestra gives you a self-hosted, YAML-defined orchestration layer that can span multiple environments and workflow types. AWS Step Functions and Azure Data Factory reduce operational work, but they keep teams inside a managed cloud service and billing model.
Yes. While Kestra itself is built in Java, its plugin and scripting model supports Python, Node.js, R, Go, shell, SQL, and other task types inside workflows. That lets teams orchestrate existing scripts instead of rewriting them into one runtime.
