Vibe-coded it? Here is how to market your app

You described an idea, an AI builder like Lovable, Bolt or Cursor turned it into a working product, and you clicked publish. That part used to take months. Now it takes a weekend.

Then nothing happens. The app is live, the link works, and nobody comes.

That is normal. Building got fast, but distribution did not change at all: people still have to hear about your product, understand it in a few seconds, and have a reason to try it. This guide is a practical order of operations for the first weeks after launch, written for solo founders who build with AI and don't have a marketer.

Step 1: Make the page ready before you send anyone to it

Every visitor you bring, free or paid, lands on one page. If that page is unclear, every channel below will look like it "doesn't work". Before you post anywhere, check five things:

1. One sentence that says what it is and who it is for. Not "the future of productivity", but "Invoices for freelance designers in 30 seconds". If a stranger can't repeat it back, rewrite it.
2. One main action. Sign up, start a trial, join a waitlist. Pick one and make it the biggest button on the page.
3. Proof that it is real. A screenshot or a short screen recording of the actual product beats any illustration. AI builders make beautiful hero sections; show the app itself.
4. A mobile check. Open your page on a phone. Social and ad traffic often arrives on a phone, so this is where first impressions happen.
5. Basic tracking. Know how many people visit and how many sign up. If you plan to run Meta ads, install the Meta Pixel and fire an event on sign-up. Without it you can still judge clicks and cost per click, but you can't see which ads bring actual users.

This takes an afternoon, and it's the highest-leverage afternoon of your launch.

Step 2: Use the free channels first

Free channels are slow and manual, but they give you something ads can't: real conversations with your first users. Those conversations tell you which words to use in your ads later.

Communities where builders hang out. Subreddits like r/vibecoding and r/indiehackers are full of people who build the same way you do. Read each community's rules first. A post that shares what you learned while building ("I built X with Lovable in two days, here's what broke") works far better than a bare link.

Launch platforms. Product Hunt, BetaList and Peerlist Launchpad exist exactly for new products. Prepare a short tagline, three or four screenshots and a first comment that explains why you built it. Product Hunt rewards preparation: line up people who genuinely care about the product before launch day, rather than asking strangers for upvotes.

Your builder's own showcase. Some AI builders run galleries of projects made with them, for example Lovable Launched. The audience there is other builders, so it is better for feedback than for customers, but it's free and fast.

Where your users already are. If your app is for dentists, a vibe-coding subreddit won't buy it. Find the forums, groups and newsletters of your actual audience and show up there with something useful.

Give this a week or two. The goal isn't big numbers. It's to learn which one-sentence description makes people click, and which makes them shrug.

Step 3: Know when paid ads make sense

Paid ads don't fix an unclear product. They make whatever you have louder. They start to make sense when:

• people who see the page understand it (Step 1),
• at least a few strangers have signed up from the free channels (Step 2), and
• you know roughly who those people are: their job, their problem, their country.

At that point Facebook and Instagram ads are often the most practical next step for a new product, because you can target by interests and location, start with a small daily budget, and see within days whether an angle gets clicks.

What usually stops solo founders isn't the money. It's the setup: a Business Manager, an ad account, a Page, a payment method, the Pixel, audiences, ad sets, creatives in several sizes, and the fear of misconfiguring a budget and waking up to a big bill.

Step 4: Run your first Meta campaign without the setup marathon

This is the problem GainAI was built for. You describe your website, your goal and your budget, by text or by voice, in one message, for example: "Promote myapp.com in the US, $10 a day, I want sign-ups."

From there, the agent:

• analyzes your site and your competitors to understand what the product is, who it's for and how others in your space talk about it;
• prepares a strategy and ad creatives: audience, countries, budget, test duration, headlines, texts and images;
• shows you everything before launch. Nothing goes live until you explicitly approve the prepared campaign, its budget and its duration.

You can launch in one of two ways:

• From the GainAI Page, without your own Meta ad account. You prepay the total campaign budget. One campaign-level budget is shared across all ads, so adding an ad doesn't multiply what you spend, and raising the total needs your approval and an extra prepayment. A small service fee applies on top of the ad budget in this mode; see pricing.
• From your own Meta account and Page. Meta charges your own payment method directly, using the budget and duration you approved.

Ads run on Facebook today; Instagram, Threads and other platforms are in the works.

After launch, automation is off by default. You can switch on Suggest mode, where the agent writes recommendations, or Experiment mode, where it can pause weak ads and test new variants inside the budget you already approved. Either way you can ask the agent at any time how the campaign is going.

New accounts get 5 free AI credits, enough for a first analysis of your site. They cover the agent's work, not ad spend.
