n8n Alternatives in 2026: 6 Open-Source, Self-Hosted Automation Tools

Quick answer
The strongest open-source n8n alternatives in 2026 are Activepieces for a similar visual builder with a permissive core, Node-RED for event-driven and IoT flows, Windmill for script-first internal tools, Kestra for declarative data pipelines, and Huginn for agents that watch the web. All can be self-hosted.

Open-source, self-hosted n8n alternatives compared: Activepieces, Node-RED, Windmill, Kestra, Huginn and Automatisch — licences, strengths, and which to pick for your workflows.

n8n Alternatives in 2026: 6 Open-Source, Self-Hosted Automation Tools

Short version: if you want n8n with a more permissive licence, use Activepieces. If your automations are really code, use Windmill. If they are data pipelines, Kestra. If they are events from devices, Node-RED. Every option below can run on your own server; star counts and licences are from the GitHub API on 18 September 2026.

Self-hosted n8n alternatives by GitHub stars

Why look beyond n8n at all

n8n is excellent and has over 200,000 stars. But it is fair-code under its Sustainable Use License, not an OSI-approved open-source licence, which limits some commercial uses, notably offering it as a hosted service to your own customers. That, and a preference for code-first tools, is what drives most searches for alternatives.

The alternatives

**Activepieces** is the closest match: a visual builder, a catalogue of integrations and AI steps. Its community edition is permissively licensed. Check that your connectors exist first; the catalogue is smaller than n8n's.

**Windmill** is script-first. Write steps in Python, TypeScript or Go and get workflows, schedules and internal UIs with permissions and audit logs.

**Kestra** (Apache-2.0) defines flows declaratively in YAML and is built for data and orchestration workloads.

**Node-RED** (Apache-2.0) is the veteran for event-driven and IoT flows, light enough for a Raspberry Pi.

**Huginn** (MIT) runs agents that watch websites and feeds and act on changes. Think self-hosted IFTTT for people comfortable with Ruby.

**Automatisch** is a Zapier-style builder, but its last code push was in February 2026, so weigh its maintenance pace before committing.

Which n8n alternative fits which kind of workflow

How to choose

  1. Look at what your workflows are.

- SaaS-to-SaaS glue: Activepieces.

- Mostly scripts: Windmill.

- Data pipelines: Kestra.

- Device and event flows: Node-RED.

  1. Check the licence against your plans.

- Reselling automation to customers needs a permissive licence.

  1. Prototype your busiest workflow first.

- Migration is a manual rebuild; there is no reliable importer.

Running several of these side by side is cheap on one small VPS. Our self-hosted productivity stack covers the rest of the setup.

Frequently asked questions

Why do people look for n8n alternatives if n8n is self-hostable?+

Mostly licensing. n8n is fair-code under its Sustainable Use License rather than an OSI-approved open-source licence, which restricts some commercial uses, such as offering n8n as a hosted service to your own customers. Teams building products on top of automation often want a permissive licence. Others want a different model entirely, such as code-first scripts or declarative pipelines.

What is the closest alternative to n8n?+

Activepieces. It has the same visual, trigger-and-action builder, a catalogue of integrations, AI steps and self-hosting through Docker. Its community edition uses a permissive licence, with some enterprise features held back. The catch is breadth: its integration catalogue is smaller than n8n's, so check the specific connectors you depend on before migrating.

Which n8n alternative is best for developers who prefer code?+

Windmill. You write steps as scripts in Python, TypeScript, Go and other languages, and Windmill turns them into workflows, schedules and internal UIs with permissions and audit logs. It suits engineering teams who find drag-and-drop builders limiting. Kestra is the other code-leaning option, defining flows declaratively in YAML, and fits data engineering work.

Is Node-RED still a good choice in 2026?+

Yes, for what it is good at. Node-RED is a long-established, Apache-2.0 licensed flow tool, strong for event-driven automation, home automation and IoT, and runs comfortably on a Raspberry Pi. It is less suited to SaaS-to-SaaS business automation, where n8n and Activepieces have far more ready-made integrations.

Can I migrate n8n workflows to another tool automatically?+

Not reliably. Each tool models triggers, credentials and data mapping differently, so exported n8n JSON does not import cleanly elsewhere. Plan a manual rebuild: start with the workflows that run most often, recreate credentials in the new tool, and run both side by side until outputs match. Rebuilding is also a good moment to delete workflows nobody uses.
