I built and launched a SaaS product at 19 | here's how it actually went...

I'm 19, studying software engineering in Karachi, Pakistan and a
month ago I decided to build something real. Not a todo app. Not a
clone. Something I could actually charge money for.

That thing is FeedbackLoop | an AI powered web and code reviewer.
You paste a URL or code snippet and get back a scored list of issues
with exact fixes for each one. SEO, performance, security,
accessibility and UX all in one report.

Here's how the month actually went.

The idea

I got tired of finishing a website and having no idea if it was
actually good. Existing tools either cost a fortune or gave you
a score with zero explanation of what to actually do about it.

I wanted something that said "here's what's broken and here's
exactly how to fix it." Simple as that.

The build

Stack I went with:

  • Next.js 14 with App Router
  • Supabase for database and auth
  • Groq API for AI analysis
  • Browserless for full JS rendering
  • Tailwind CSS
  • Deployed on Vercel

Sounds straightforward. It was not.

The part that nearly broke me

The API integration was genuinely painful. I started with Gemini
as my AI provider and spent days getting everything connected and
working. Then it broke. Just stopped working the way I needed it to.

Had to rip it out and switch everything over to Groq. That was not
a fun afternoon.

But honestly it was worth it | Groq is faster and has a generous
free tier which matters a lot when you have zero users and zero
revenue.

What I actually built

By the end of the month FeedbackLoop had:

  • URL and code review with severity scored issues
  • Individual scores for SEO, Performance, Security, Accessibility and UX
  • Full JavaScript rendering so React and Next.js apps get properly analyzed
  • WordPress specific fix guides in plain English for non-technical users
  • Plugin recommendations for WordPress sites
  • Downloadable score card to share your results
  • 3 plan tiers | Free, Developer ($9/mo), Pro ($19/mo)
  • Early bird deal | first 100 users get Pro free for 3 months

Why SaaS and not just another portfolio project

Honestly I just wanted to do something different. Every software
engineering student has the same portfolio | todo app, weather app,
maybe a clone of something. I wanted to build something that could
actually make money and solve a real problem.

Even if FeedbackLoop fails completely I learned more in this one
month than in any classroom. Payments, auth, APIs, rate limiting,
database design, deployment, marketing | all of it.

Where I am now

Just launched. Zero paying users. Zero free users if I'm being
completely honest.

But it's live, it works, and I'm proud of it.

If you want to try it | no signup needed, there's a free preview
right on the homepage.

And if you're a student thinking about building something real |
just start. It doesn't have to be perfect. Mine definitely isn't.
But it exists and that's more than most people can say.
