Vibe Coded Mini App Examples Your Marketing Team Can Built Today
How many times have you had a great idea for a marketing tool, a campaign dashboard, or a simple process improvement, only to be told it's "not on the engineering roadmap"?
We've all been there.
With AI, marketers who understand technology and how to work with code can create anything from
website tools to get traffic
quizzes & tools to capture leads, or
internal tools to improve processes.
This is where the idea of "vibe coded" mini-apps comes in.
And, apps like Lovable, Replit, Cursor, or Bolt can help you do it.
The trick? You also need how to implement, embed, or setup to run on a website. That’s why we built Growth Vibers, a community of technically minded growth marketers:

If you're a marketer who's curious about technology, coding, and building your own solutions, this is your tribe. No gatekeeping, no dumb questions. Just practical learning and support.
What is a "Vibe Coded" App, Really?
Think of "vibe coded" as the practical middle ground between a messy spreadsheet and a full-blown software application.
It’s a tool built with a simple goal:
Does it work and solve our immediate problem?
It doesn't need to be perfectly polished, scalable to millions of users, or have the prettiest code. It just needs to have the right "vibe"—it feels right, it's useful, and it saves your team time and headaches. It’s about utility over perfection.
So, what does this look like in the real world?
Example 1: X-pense - Expense Management Software for SMEs
We built X-pense in a weekend with some friends, but took 4 weeks to iron out the bugs, setup a Github, Supabase, custom domain, emails, marketing website (still being built) etc.
The app?
Upload a CSV of your expenses and it helps you categorize the expenses and identify the “fat” and where to cut it.
Example 2: Employee Advocacy Leaderboard
Giulia de Oliveira Camargo from Chameleon built a Leaderboard vibe coded on Lovable to track her team’s performance in personal brand on LinkedIn to support social selling.
This is a great example of an internal tool for the marketing team!
Example 3: Training ROI Calculator
A simpler example here, a Training ROI Calculator.
Every training or services company struggles to prove they are a “must-have” and not a “good-to-have”. The best way to do so is creating an ROI calculator either as a spreadsheet or a live calculator on a website.
I used Lovable to create it, but run a Deep Research prompt on Gemini to give me instructions as if it were a product manager in order to achieve it.
