Vibe coding: prototyping without knowing how to code
tier II · practitioner · 8 min · interactive article ✦
The term appeared in early 2025 and went around the tech world in weeks: vibe coding means building software by describing what you want in plain language, and letting the AI write the code. You describe, it assembles, you test, you adjust. For a manager, it's less a technical curiosity than a shift in the balance of power: an idea no longer has to wait for budget to become demonstrable.
What it concretely changes
Yesterday: an idea for an internal tool = a requirements doc, a budget call, a vendor, six weeks. Today: an hour of dialogue with a vibe-coding tool produces a working prototype — a simulator, a dashboard, a smart form — enough to test the idea with real users and walk into a committee with something clickable rather than slides.
the vibe coding loop — and its official exit: the IT department
Vibe coding doesn't replace your IT department. It replaces the slide deck: instead of describing your idea in slides, you show it as something clickable.
The method in four reflexes
Describe the use, not the tech: “a tool where my team logs requests, with a status and a priority” beats any approximate technical vocabulary.
Start tiny: one feature that works, then add. The prototypes that fail are the ones trying to do everything in the first prompt.
Test at every iteration: click, break, ask again. Your user's eye is the quality loop.
Know when to stop: a convincing prototype = head to IT for the serious version (security, data, maintenance).
The limit to know
A vibe-coded prototype is not a product: no serious authentication, no regulated data handling, no maintenance. The classic “shadow IT” trap: the patched-together tool that becomes critical without ever being secured. The rule: vibe coding is for proving value, IT is for putting it into production. Both win when the manager knows where the boundary lies.
test yourself — just like in the path
Your vibe-coded request-tracking prototype is a hit. The team wants to use it Monday with real customer data. You say:
✓ Exactly the boundary: real data = real requirements (security, GDPR, maintenance). The prototype did its job — convince. The rest is a project.
Beware of shadow IT… or the opposite waste. The right answer is in between.
Going deeper
What can you reasonably prototype?
Anything that shows on screen and can be tested by clicking: calculation simulators, dashboards, smart forms, internal app mockups, sorting or prioritization tools. What's a poor fit: anything touching production data, payments, or authentication.
How long for a first prototype?
For someone who has never coded: count one to two hours for a first simple, working tool, following the “one feature at a time” rule. Level 17 of the path has you live exactly this loop, on a case from your job.
Frequently asked questions
What is vibe coding?
Building software by describing what you want in plain language: the AI writes the code, you test the result and adjust the description. Ideal for exploring an idea fast.
Can a vibe-coded prototype go to production?
Rarely as is: security, robustness and maintenance still need hardening. It's an excellent tool for exploration and proof of value, not a production workshop.
Does vibe coding replace developers?
No. It speeds up exploration and prototyping; reliable, maintainable production remains a profession of its own.
Do you need to code to do vibe coding?
Not to explore an idea. But understanding the limits helps you avoid mistaking an impressive demo for a ready-to-use product.
