By Tori, last checked 2026-10-08. Each entry below was read against its own page or licence. The verdicts are written for someone who wants to use a tool in something they sell or publish; a skip is often about a licence or a heavy setup, not about quality.

One by one
n8n Skip it
A popular workflow tool with thousands of templates. Its Sustainable Use License says you may use or modify it only for your own internal business purposes or for non-commercial or personal use, and may pass it on only free of charge and non-commercially. Files marked .ee need a separate Enterprise License. Copy only the idea of a browse-and-import template library.
Licence. Sustainable Use License (fair-code, not open source). Cost. Free software.

Paperclip Copy the idea, skip the tool
An open “company of AI helpers” with goals, budgets, approvals and shareable company templates. MIT. Runs on your own machine and does not talk to platforms. A comparison to learn from, not a part to plug in: borrow the budgets with warnings, the approvals and the portable templates.
Licence. MIT. Cost. Free software.

NVIDIA OpenShell Copy the idea, skip the tool
A sandbox that runs AI helpers under a policy you write. Apache-2.0. Pre-1.0 and heavy for a first-time user; revisit it when you let helpers run unattended.

Internal use versus a product
Using n8n to automate your own business is the case its licence allows. The line is selling it, hosting it for customers, or building a product whose value is the tool itself.
If you only need a few automations, the small steps are often shorter to write as plain code you own than to carry a tool whose licence you must keep checking.
Questions
Is n8n free for commercial use?
Only for your own internal business purposes, or non-commercial and personal use. Passing it on to others must be free and non-commercial.
Is Windmill free to resell?
No. The free Community Edition program files forbid reselling, serving as a managed service and wrapping without a commercial licence.
Do I need a sandbox for AI helpers?
Not for a first project. The Atlas suggests revisiting NVIDIA OpenShell when you let helpers run unattended.
