Ship Small, Ship Fast

You have a product idea. The temptation is to build everything. The indie-hacker move is the opposite: build the smallest useful version and get it in front of people this week.

That smallest version is your MVP — Minimum Viable Product. With vibe coding, you can go from idea to working MVP in hours instead of months, because AI writes the boilerplate while you steer the product.

In this lesson you'll learn to scope ruthlessly and prompt AI to build only what matters.

What an MVP Actually Is

An MVP is not a half-broken app. It's a complete experience around one core action. Everything else is cut.

Ask yourself: what is the one thing a user does that delivers the value? For a note app, it's "write and save a note." Not folders, not sharing, not themes — just that one loop done well.

If a feature doesn't support the core loop, it's not in the MVP. Write that core loop in one sentence before you prompt anything.

Find the Core Loop with AI

Stuck on what to cut? Let AI play product manager. Hand it your idea and ask it to find the single core loop and strip the rest.

This turns a fuzzy vision into a tight, buildable scope you can actually ship.

I want to build a habit-tracking app. Act as a product strategist.

1. Identify the SINGLE core loop a user repeats daily.
2. List the absolute minimum features needed for that loop.
3. List 5 features I might be tempted to add but should CUT for the MVP.
4. Give me a one-sentence scope statement.

Be ruthless — favor shipping this week over completeness.

Pick a Boring, Fast Stack

For an MVP, the best stack is the one that ships fastest — not the trendiest. App builders like Bolt, Lovable and Replit let AI generate a full working app in the browser. v0 is great for the UI, Cursor for hands-on edits.

Pick one tool and commit. Switching tools mid-MVP burns the time you saved. A single-page app with local storage is often enough to validate an idea.

Prompt the First Version

Now describe the whole MVP in one clear build prompt: the core loop, the screens, and the data. Give AI the scope statement you wrote earlier so it doesn't gold-plate.

Paste this into Bolt, Lovable or Cursor and you'll get a working starting point in seconds.

Build a single-page habit tracker web app. Keep it minimal — this is an MVP.

Core loop: user adds a habit, then checks it off each day.

Requirements:
- One screen, no routing
- A text input + Add button to create habits
- A list of habits, each with a checkbox for today
- Save everything in browser localStorage so it persists on refresh
- Clean, modern styling; mobile-friendly

Do NOT add accounts, settings, charts, or categories yet.

Keep the Code Tiny

An MVP's whole logic often fits in a few small functions. Here's the persistence heart of that habit tracker — the kind of snippet AI generates for the core loop.

Notice it does exactly one job: save and load habits. No frameworks, no ceremony.

function loadHabits() {
  return JSON.parse(localStorage.getItem('habits') || '[]');
}

function saveHabits(habits) {
  localStorage.setItem('habits', JSON.stringify(habits));
}

const habits = loadHabits();
habits.push({ name: 'Drink water', doneToday: false });
saveHabits(habits);

console.log('Saved habits:', loadHabits().length);

Timebox the Build

An MVP without a deadline becomes a forever-project. Give yourself a hard timebox — say, one weekend — and treat anything that doesn't fit as v2.

When AI suggests a fancier approach, ask: "Does this help me ship by my deadline?" If not, defer it. Speed is the whole point; polish comes after real users prove the idea is worth polishing.

Fake the Hard Parts

Some features look essential but are slow to build. For an MVP, you can fake them. No payment system yet? Use a Stripe payment link. No real backend? Store data in localStorage or a single Google Sheet.

This is the "Wizard of Oz" trick: the user gets the experience even if a human or a shortcut powers it behind the scenes. You're testing demand, not building infrastructure.

My MVP needs users to 'upgrade to Pro' but I don't want to build billing yet.

Suggest the fastest fake-it approach:
- A simple way to capture intent (e.g. a Stripe Payment Link or a waitlist form)
- How to unlock 'Pro' manually for now
- What I should measure to know if it's worth building real billing

Keep it shippable today.

Make It Demoable

An MVP must be shareable — a link you can send to a friend or post online. Replit, Bolt and Lovable give you a live URL instantly; with Cursor you can deploy to Vercel in a click.

If you can't send someone a link in the next hour, your MVP is still too big. The link is what turns your idea into feedback.

Help me get my habit-tracker MVP online as fast as possible.

- It's a static single-page app (HTML/CSS/JS, localStorage)
- I want a public URL I can share today

Give me the quickest path: which host, and the exact steps. Prefer one-click options over manual setup.

Resist Feature Creep

The biggest MVP killer is your own enthusiasm. Every "wouldn't it be cool if…" delays the ship date.

Keep a v2 list: a text file where every new idea goes to wait. This calms the urge to build it now while making sure good ideas aren't lost.

Your job at MVP stage isn't to impress — it's to learn fast and cheap. A boring app that ships beats a brilliant one that never does.

A Repeatable MVP Recipe

Put it together into a recipe you can reuse for any idea:

  • 1. Write the core loop in one sentence.
  • 2. Ask AI to cut everything else.
  • 3. Pick one fast tool and prompt the whole thing.
  • 4. Fake the hard parts.
  • 5. Deploy to a shareable URL.
  • 6. Timebox it and stop.

Follow this and you'll turn ideas into live products faster than most teams write a spec.

Recap: Smallest Useful Version

You learned the indie-hacker way to start a product: build the smallest useful version and ship it.

  • Define the core loop in one sentence.
  • Let AI ruthlessly cut scope.
  • Prompt the whole MVP in one fast tool.
  • Fake hard parts and deploy to a shareable link.
  • Timebox it and park extras on a v2 list.
