The short answer

kestra-io/kestra (27,560 stars, Java) is an event-driven orchestration and scheduling platform designed for mission-critical applications. Instead of writing Python DAGs, you declare workflows in YAML, and Kestra handles scheduling, retries, and state. It is declarative, has a built-in UI, and runs anywhere - Docker, Kubernetes, or cloud.

Kestra vs Airflow vs Temporal

Airflow (46,389 stars) is the veteran choice for Python data pipelines. Temporal (22,126 stars) shines for durable application workflows. Kestra wins when you want infrastructure-as-code style pipelines that non-engineers can read.

Build your first workflow

Create hello.yaml:

id: hello
namespace: demo
inputs:
  - id: name
    type: STRING
tasks:
  - id: greet
    type: io.kestra.plugin.core.log.Log
    message: Hello {{ inputs.name }}
triggers:
  - id: daily
    type: io.kestra.plugin.core.trigger.Schedule
    cron: "0 9 * * *"

Then run:

docker run -p 8080:8080 kestra/kestra:latest server local
# Open http://localhost:8080, create the flow, and execute it

The workflow runs every day at 09:00, and every execution is visible in the UI with logs and metrics.

FAQ

Do I need to learn a new language? No - flows are YAML. Task types cover shell, Python, SQL, HTTP, and 700+ plugins.

Can it replace Airflow? For many teams yes, especially where DAGs are mostly standard patterns. Heavy Airflow ecosystems with hundreds of custom operators may prefer staying.

Is it free? The core is Apache-2.0 licensed open source.
