Most business leaders discover n8n while searching for an automation platform that offers flexibility without the constraints of enterprise contracts. They compare it with Zapier, Make, or Activepieces, then encounter a critical question: is n8n open source OSI approved?

This matters because long-term automation decisions impact security audits, compliance approvals, vendor dependencies and integration paths. Companies exploring n8n integrations for workflows, CRM syncing and HubSpot automation frequently need clarity on this specific legal and operational point.

Is n8n open source OSI approved or not?

n8n is open source but not OSI-approved because its license includes commercial restrictions preventing full OSI compliance.

Understanding OSI Approval and Why Businesses Care

The Open Source Initiative (OSI) defines whether a project truly qualifies as open source. Approval ensures:

• No vendor lock

• Free redistribution rights

• Source code modification without commercial limitation

• Certainty for due-diligence teams and software procurement

Without OSI approval, companies must interpret licensing clauses carefully, especially when embedding the tool into SaaS products or client ecosystems.

What License Does n8n Use?

n8n previously used the Apache 2.0 license, which is OSI approved. However, to protect core intellectual property from commercial competitors, its license changed to the Sustainable Use License (SUL).

The SUL allows you to view and modify the source code, but restricts certain use cases—especially commercial redistribution. This restriction breaks OSI’s criteria, meaning:

n8n is open source in a practical sense, but not legally OSI approved.

For teams running internal automation, this typically causes no issue. But for B2B software vendors, compliance triggers deeper review.

Why People Keep Asking This Question

This debate exists because n8n markets itself as “source available.” For non-technical founders, the phrase sounds like open source. Procurement teams encounter confusion when legal departments ask whether they can:

• Package n8n inside their SaaS workflows

• Offer n8n-powered automation to customers

• Monetize a product built directly on top of n8n

In most cases, n8n allows usage but not unrestricted commercial distribution.

Real-World Scenarios

Scenario 1: The Confused CTO

A startup CTO wants to automate CRM processes between HubSpot and a custom ERP. They like the flexibility of n8n and assume they can deploy it across client portals. Once the enterprise client asks for OSI certification, the deal stalls for weeks.

Scenario 2: Procurement Roadblock

A fintech team passes a vendor security questionnaire requiring confirmation of OSI-approved components. n8n fails the compliance question, forcing the engineering team to consider internal forks or pick another automation engine.

Scenario 3: The Wrong Assumption

A founder builds automation features into their SaaS using n8n workflows. Six months later, investors challenge product liability risks because of non-OSI licensing. The founder now faces expensive re-architecture.

In all three cases, the license decision not the technology caused the problem.

How n8n Compares to True OSI-Approved Platforms

This explains why competitors frame n8n as “not fully open source,” especially in developer communities like Hacker News.

Does The Lack of OSI Approval Make n8n Bad?

Absolutely not.

n8n is a powerful workflow engine with advantages over typical no-code tools. However, if your procurement process demands OSI compliance, n8n cannot legally meet that requirement today.

Choosing n8n becomes a strategic licensing decision rather than a simple feature comparison.

Should Your Business Still Use n8n?

Use n8n confidently if:

• You want automation without per-workflow limits

• You manage workflows internally

• You don’t resell automation as a product feature

Avoid it if:

• You plan to embed n8n into your SaaS

• You need OSI-compliant audits

• You require a license with zero commercial constraints

Conclusion

Is n8n open source OSI approved?
No.
n8n is a source-available platform with restrictions that prevent OSI approval. It remains an excellent choice for internal workflow automation, but businesses should understand licensing implications before architecting mission-critical systems on top of it.
