We put 5 “vibe coding” tools to the test — tools that promise to turn ideas into working products with almost zero engineering.

Tools we tested:

✅ Lovable

✅ Replit

✅ Firebase

✅ Bolt

✅ Vercel

Our goal?

Build a Calendly-style scheduling app, complete with:

– Multi-host availability

– Calendar integration

– Basic UI and backend

– Simulated booking flows

What started as a fun experiment turned into a serious teardown of what works, what breaks, and where each tool shines (or fails hard).

If you're a PM, indie builder, student, or founder trying to ship MVPs faster using AI — this is for you.
