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.
