Kestra: Open Source Alternative to n8n

Kestra is an open-source, event-driven orchestration platform where workflows are defined in YAML rather than built purely through a visual editor. It's licensed under Apache-2.0, a fully permissive license, unlike n8n's fair-code Sustainable Use License.

What is Kestra?

Kestra targets data engineering, AI, and infrastructure orchestration as one unified platform rather than general-purpose business automation. Workflows are version-controlled YAML files that can be reviewed and deployed through standard CI/CD, while tasks themselves can run in Python, Bash, Node.js, Go, or containers. It ships with 1400+ plugins covering cloud providers, databases, and data tools like dbt and Airbyte.

Kestra is especially useful for:

• data and platform engineering teams orchestrating pipelines, not just app-to-app triggers
• teams that want workflows reviewable in pull requests, not stored in a database-backed UI only
• AI teams orchestrating RAG pipelines, model retraining, and evaluation workflows

Kestra vs n8n

Feature	Kestra	n8n
Core license	Apache-2.0 (fully permissive)	Sustainable Use License (fair-code)
Workflow definition	Declarative YAML, CI/CD-friendly	Visual builder, JSON-based
Primary focus	Data/infra orchestration, cross-team	General business & app automation
Plugins	1400+	400+
Enterprise	Separate paid Enterprise Edition (SSO, multi-tenancy)	Separate enterprise license

Choose Kestra if your workflows are closer to data pipelines or infrastructure orchestration, or if you want YAML-based workflows that live in Git alongside your code.

Choose n8n if you want a primarily visual builder for general business process automation.

FAQ

Is Kestra fully open source?

Yes, the core platform is Apache-2.0 licensed — a fully permissive license with no usage restrictions. A separate paid Enterprise Edition adds SSO, multi-tenancy, and hybrid/air-gapped deployment for larger organizations.

What's the difference between Kestra and n8n?

Kestra defines workflows declaratively in YAML and is aimed more at data/infrastructure orchestration across teams, while n8n is a visual, general-purpose automation builder aimed at connecting business apps. Kestra's license (Apache-2.0) is also more permissive than n8n's fair-code license.

Is Kestra a good fit for non-developers?

Kestra is designed so both engineers (working in YAML) and non-engineers (using the UI) can build workflows and stay in sync, though its data/infrastructure focus makes it more developer-oriented than n8n out of the box.
