How I Built and Launched an App in Under a Week 🚀

The Challenge

Last week, I gave myself what felt like an impossible challenge:
Build and launch a free app on Product Hunt in under a week.

I had no grand plans, no fancy setup—just a wild idea and some powerful tools:

• Cursor AI

• Gemini 2.5 Pro model

Oh, and here’s the kicker: I wasn’t going to write a single line of code.

The Journey

The journey started on Tuesday.

In just 2 hours, I built the first version of the app—v0.01—and hosted it on Vercel without even a proper domain name. It wasn’t perfect, but it worked. (Here’s proof👇)

From there, I stuck to one rule:
Add one new feature every single day.

Launch Day Results

By Sunday, PostRoast was ready for its big moment. I launched it on Product Hunt, and here’s what happened:

• 49 upvotes (way more than I expected!)

• #12 position on the leaderboard

• 558 users and counting

• 1 ad spot sold 🤫

No, I didn’t make a fortune—that wasn’t the goal. The real win was proving that I could take an idea and turn it into something real fast.

What I Learned

This experience taught me one big lesson:

Once you take the first step, you’ll figure out the rest along the way.
