n8n vs Node-RED
Both are free/open-source alternatives to Zapier. Here's how they stack up — verified facts, no spin.
n8n
TOP PICKPowerful, self-hostable workflow automation with a large node library.
n8n is the tool most people mean by "self-hosted Zapier." It offers a visual workflow editor with 400+ integration nodes, branching logic, and code steps, plus AI/agent nodes for LLM-driven automations. You can self-host it for free with Docker and keep every workflow and credential on your own server, or use n8n's paid cloud. Note the license: n8n uses the source-available Sustainable Use License, not an OSI-approved open-source license.
Node-RED
Fully open-source, flow-based programming that runs on hardware as small as a Raspberry Pi.
Node-RED is a mature, Apache-2.0 flow-based automation tool built on Node.js. You wire together "nodes" in a browser editor to move and transform data between APIs, webhooks, MQTT, databases, and thousands of community-contributed integrations. It is the most sovereign option here on licensing and hardware: it runs locally, stores flows as open JSON files, and is light enough for a Raspberry Pi. Its roots are in IoT and event automation rather than SaaS-to-SaaS connectors.
Side by side
| n8n | Node-RED | |
|---|---|---|
| Sovereignty Score | 82 | 95 |
| Open source | No | Yes |
| Self-hostable | Yes | Yes |
| Local-first | Yes | Yes |
| License | Sustainable Use License (source-available, fair-code; not OSI-approved) | Apache-2.0 |
| Pricing | Free to self-host; paid n8n Cloud tiers available | Free / self-host |
n8n is Macrostack's recommended Zapier alternative, so it's our pick here.
n8n
Strengths
- +Runs entirely on your own server via Docker; workflows and credentials stay on your infrastructure
- +Very large node library (400+ integrations) plus HTTP and code nodes to reach almost any API
- +Strong branching, error handling, and built-in AI/agent nodes for LLM workflows
- +Very active project and large community (190k+ GitHub stars, near-daily commits)
- +Workflows export as JSON, so they are portable between your own n8n instances
Trade-offs
- −License is source-available (Sustainable Use License), not OSI open-source; it permits internal/self-hosted business use but restricts offering n8n itself as a hosted service to third parties
- −Self-hosting requires running and maintaining a server and database
- −Fewer prebuilt app integrations than Zapier's 7,000+ catalog; some connections need HTTP/API setup
- −Steeper learning curve than a pure no-code tool for complex flows
Node-RED
Strengths
- +Fully open-source under Apache-2.0, an OSI-approved license
- +Runs entirely locally on modest hardware, including a Raspberry Pi
- +Flows are stored as open JSON files you own and can version-control
- +Huge library of community nodes and a long, stable track record
- +Excellent for IoT, webhooks, MQTT, and custom logic
Trade-offs
- −Flow-based, developer-leaning model; less turnkey than Zapier's app-picker for connecting SaaS tools
- −Many SaaS integrations rely on community nodes that vary in quality and maintenance
- −You maintain the runtime, updates, and any exposed endpoints yourself
- −Building polished multi-app business automations takes more effort than a no-code UI
