How it works

A tutorial shows you someone else's workflow. A brief makes you build your own.

The client brief

The spec you would write after discovery: inputs, constraints, edge cases and pass criteria, already scoped so you can start building.

02·Your stack
A three-node workflow on an n8n canvas: a webhook trigger, a Google Drive create-folder step and a Notion update-page step.

Your stack

Fire up n8n or Make. Use your own credentials. No toy editors to learn and immediately abandon.

The grader

Paste your webhook. We blast it with test payloads and report exactly what passed, what broke, and the input that caused it.

The library

Nine tracks, from your first webhook to a full client build.

View all 71 briefs

Real APIs. Real failure modes. Every brief runs against simulated APIs with real auth, pagination, and rate limits. The walls you hit here are the ones you'll hit on the job.

Public portfolio

Prove you can build.

Your graded attempts, first-pass rates, and domain expertise log to a public URL. Send it to prospects to prove you actually ship.

A per-domain breakdown, so a payments client sees payments work.
First-pass rate, not just completion - the number that says you get it right the first time.
A track certificate on completion, with the full case log attached.

Nox AI

A senior reviewer, not a hint button.

Hand your workflow to Nox. It tells you what failed, why it failed, and what to change - exactly what you'd hear in a real workflow review.

Questions

Before you start.

What is Nodox.ai?

Nodox gives you client-style briefs (challenges) and a sandbox of simulated APIs like Stripe, Slack, and CRM-style endpoints. You build the workflow in your own n8n or Make, and we grade it against real test cases.

How is Nodox different from tutorials?

A tutorial shows you someone else's workflow. Nodox hands you a brief with inputs, constraints, and pass criteria, then grades the workflow you build yourself against real test cases.

Do I need prior experience?

No. There are briefs for every skill level, from your first webhook to full client-style projects.

What tools does Nodox support?

Any tool that can call a webhook. Nodox works with n8n or Make, and you can also use it with other webhook-capable tools. We validate your webhook responses and give instant feedback.

Can I use Nodox for free?

Yes. 19 free briefs cover the fundamentals and error handling, no payment required.

How does the grading work?

You submit your webhook URL, we send test data, and our system checks the response structure, data transformations, and edge case handling against what the brief asks for.
