🧪 Replit Agent 3 vs Lovable vs Bolt — What Really Happened When I Tested Them

Replit just launched Agent 3 and there’s been a lot of hype about how it can build apps automatically.I was curious too — so instead of just reading the launch notes, I put it head-to-head with Lovable and Bolt.

I tried three very different builds with each tool:

a full CRM system
a simple game
a landing page

I wanted to see, in real scenarios, which one actually delivers.

Here’s what I found:

The promises and the reality don’t always match.
Each platform has strengths, but none are “magic.”
Replit Agent 3, in my tests, didn’t come out on top in any of the three builds.

I recorded the entire process — successes, failures, and workarounds — so you can see for yourself how each tool performed without spending hours testing them.

If you’re evaluating these platforms for your own projects, this walkthrough might save you time

Would love to hear: what’s been your experience with these new AI-app builders?
