Two Architectures, Two Philosophies

Universal Orchestration: Pipelines and Workflows

Declarative orchestration layer where YAML describes intent and any language executes. Orchestration is configuration, not code. Data pipelines, infrastructure automation, and business processes run from a single control plane without forcing every task into one language.

"How do we run data pipelines, infrastructure jobs, and business workflows from one place?"
Python DAG Execution Engine

A Python-based workflow engine where DAGs are executable programs. Workflows are Python code that the scheduler runs. Everything—scheduling, dependencies, retries—is defined in Python and tied to the Airflow runtime.

"How do we schedule and monitor our Python data pipelines?"

Python Pipeline Scheduling vs. Universal Workflow Orchestration

Universal Workflows
  • Data pipelines, infrastructure automation, business processes, AI workflows
  • Multi-language: Python, SQL, Bash, Go, Node.js, R
  • Event-driven at core: respond to real events, not just schedules
  • Self-service for non-engineers via Kestra Apps
  • One control plane for the entire organization
Data Pipelines for Python Teams
  • Schedule-first pipeline orchestration (event-driven features added in v3)
  • Python workflow definitions (Bash/SQL via operators)
  • Data engineering scope
  • Limited multi-tenancy
  • Serves Python-native data teams

Airflow works well for Python-native teams invested in the Airflow ecosystem, especially with Airflow 3's improved event-driven features and Task SDK. Kestra is the right choice if you need multi-language teams to contribute in YAML, event-driven execution as a first-class primitive, or orchestration that spans data, infrastructure, and business workflows.

Time to First Workflow

Airflow's standalone command works for local development, but production deployments need an API server, DAG processor, metadata database, and executor configured separately. Kestra's single Docker Compose command stands up everything in a format that's already production-shaped.

~5

Minutes
curl -o docker-compose.yml \
https://raw.githubusercontent.com/kestra-io/kestra/develop/docker-compose.yml
docker compose up


# Open localhost:8080
# Pick a Blueprint, run it. Done.

Download the Docker Compose file, spin it up, and you're ready (database and config included). Open the UI, pick a Blueprint, run it. No Python environment, no DAG library to configure.

~30

Minutes
pip install apache-airflow
pip install apache-airflow-providers-standard


# Dev: airflow standalone (SQLite, no parallelism)
# Production: configure API server, DAG processor,
# metadata DB, and executor separately
# Then write your DAGs in Python...

The standalone command gets a dev instance running quickly, but on SQLite with no parallelism. Production requires installing providers, configuring the API server, DAG processor, metadata DB, and executor separately.

YAML Anyone Can Read vs. Python Only Devs Can Write

Kestra: Readable by Your Whole Team

YAML is readable on day 1. Our docs are embedded in the UI for easy reference, the AI Copilot writes workflows for you, or start with our library of Blueprints. No Python knowledge required to understand or modify a workflow.

Airflow: Python knowledge required for workflow authoring

DAG definitions, retry logic, and scheduling are all Python code. Airflow can run Bash and SQL via operators, but modifying orchestration logic requires Python. Non-Python contributors can view runs in the UI but can't author or edit workflows directly.

Full-Stack Orchestration vs. Python Pipeline Scheduling

Kestra Image

Orchestrate across data pipelines, infrastructure operations, business processes, and AI workflows in one unified platform. Event-driven at its core, with native triggers for S3, webhooks, Kafka, and message queues.

Competitor Image

Purpose-built for Python data pipeline scheduling. Airflow 3 adds event-driven Asset Watchers, but the core is schedule-driven. Infrastructure automation and business processes are possible via Python but not first-class use cases.

Kestra vs. Apache Airflow 3 at a Glance
Workflow definition Declarative YAML Python DAGs
Languages supported Any (Python, SQL, R, Bash, Go, Node.js) Python-first (Bash/SQL via operators; multi-language Task SDK experimental)
Architecture Event-driven at core Schedule-first (event-driven Asset Watchers added in v3)
Assets and lineage Data and infrastructure assets Data assets only
Multi-tenancy Namespace isolation + RBAC out-of-box Limited
Deployment Single service (Docker Compose) API server + DAG processor + metadata DB + executor
Self-service for non-engineers
Kestra Apps
UI is observability-focused, no self-service triggers
Human-in-the-loop
Native task types
Requires custom operator or external tooling
Infrastructure automation
Native support
Possible via Python operators, not a primary use case
Apple ML team success story

“We switched from Airflow because we want engineers solving problems, not coding orchestration. Kestra delivers end-to-end automation with the robustness we need at our scale. Few companies operate at this level, especially in AI/ML.”

Kestra Is Built for How Data Teams Actually Work

No refactoring required
No refactoring required

Bring existing Python scripts, SQL queries, and Shell commands. Kestra orchestrates them in YAML without wrapping them in decorators or operators. Your code stays portable and your team stays unblocked.

Orchestrate beyond data pipelines
Orchestrate beyond data pipelines

Data pipelines, infrastructure automation, and business processes run from one platform. Airflow focuses on data pipeline orchestration. Infrastructure and business workflows are possible through Python operators but aren't first-class use cases.

Event-driven, not just scheduled
Event-driven, not just scheduled

Native triggers for S3, webhooks, Kafka, database changes, and API events. Airflow 3 added Asset Watchers for event-driven scheduling, but triggers in Kestra are first-class YAML declarations, not layered onto a schedule-first core. Unlimited event-driven workflows in open source.

The Right Tool for the Right Job

Choose Kestra When
  • Your team writes Python, SQL, Bash, and dbt, and you want orchestration that doesn't force everyone into Python decorators.
  • You need event-driven workflows that respond to real-time events, not just cron schedules.
  • You're managing data, infrastructure, and business processes and want one control plane.
  • Non-engineers need to trigger or monitor workflows without writing code.
  • You're evaluating orchestrators and want to compare architectures before committing.
Choose Airflow When
  • Your team is Python-native and invested in the Airflow ecosystem: custom operators, trained staff, institutional knowledge.
  • You're running on managed services (MWAA, Cloud Composer) and are locked into the Airflow ecosystem.
  • Python-based DAG definitions and Airflow's scheduling model fit your team's workflow.
  • You have significant custom operator libraries you'd need to rebuild elsewhere.
