n8n vs Node-RED
Both are alternatives to Zapier. Here's how they stack up — verified facts, no spin.
Also searched as Node-RED vs n8n — same comparison, one verdict.
Node-RED is open source (Apache-2.0) and n8n is not (Sustainable Use License (source-available, fair-code; not OSI-approved)) — so the real question is whether you want to own the workflow automation & ipaas stack or rent it.
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
10 points of comparison, every one read from a verified field. Green marks the side that wins a row outright. A dash means we do not hold that fact — never that it is zero.
| n8n | Node-RED | |
|---|---|---|
| Sovereignty ScoreOur transparent 0–100 composite for data ownership and exit cost. | 82 | 95 |
| Open source | No | Yes |
| Self-hostable | Yes | Yes |
| Local-first data | 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 |
| RAM to run it wellThe figure that actually matters, not the vendor's minimum. | 2 GB, and 4 GB once workflows run concurrently | 1 GB for a real flow set |
| Realistic running costWhat the box costs each month if you run it yourself. | $12–25/mo on a small VPS | $6–12/mo, or free on hardware you already have |
| Setup timeHonest first-install estimate, not the marketing quickstart. | 45 minutes | 20 minutes |
| Ongoing maintenanceThe part nobody budgets for. | Active. n8n ships fast and node changes occasionally break workflows. | Low, but contributed nodes are the risk surface. |
n8n is Macrostack's recommended Zapier alternative, so it's our pick here.
Weighing both against staying on Zapier? Is Zapier free? What it actually costs →
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
Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose n8n
if runs entirely on your own server via Docker; workflows and credentials stay on your infrastructure.
Choose Node-RED
if you want the source and the option to fork it, and fully open-source under Apache-2.0, an OSI-approved license.
Neither, yet
if both carry a real cost you should weigh first — 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, and flow-based, developer-leaning model; less turnkey than Zapier's app-picker for connecting SaaS tools. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
What it takes to run these yourself
Real requirements and honest running costs, not the vendor quickstart.
n8n vs Node-RED — common questions
Is n8n a better fit than Node-RED for workflow automation & ipaas?
It depends on what you are optimising for, and the honest split is this: Node-RED scores 95 to n8n's 82 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. n8n earns its place on a different axis — runs entirely on your own server via Docker; workflows and credentials stay on your infrastructure. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
n8n keeps its data local or in open formats, so leaving is an export rather than a negotiation. Node-RED is still self-hostable, so the files stay on your server either way — but it is not local-first by design, so check what its export produces before you rely on it.
Can I self-host n8n or Node-RED?
Both can be self-hosted. The difference is what it costs you in time rather than whether it is possible — see the setup and maintenance rows above.
Are n8n and Node-RED both alternatives to Zapier?
Yes — both appear in our Zapier comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off Zapier and now choosing between the two replacements, which is a narrower and much easier question.
