How I got 500+ devs to try my AI app builder in a week (solo founder, no ads)

I’m Balram Kapoor, a solo dev from India. I spent the last few months building GenVibe, an AI app builder for developers.

In the first week after launch, 500+ people signed up and a few upgraded to paid – all without ads or a marketing budget.

What makes it different:

• Built for creators

• You can export and own the code (no platform lock‑in)

• Free tier uses the best models so you can actually build something useful

I’d love feedback from this community:
If you already use tools like Bolt/Lovable/Emergent, what would make you switch?
