⚡ Replit Agent 3 vs Lovable vs Google Gemini

I put Replit Agent 3 head-to-head against Lovable and Google Gemini, and it feels like we’re seeing the start of a big shift in AI app builders.

Agent 3 doesn’t just write code — it spins up a virtual browser, tests the app like a real user, finds bugs, and fixes them on its own in a loop. Add to that the jump from 20 minutes to over 200 minutes of unsupervised runtime, and you’ve got something that can turn an idea you speak into your phone into a working app by the time you’re back from a walk.

The Slack bot builder also feels huge. What used to be painful is now a guided setup, which could make deploying AI agents inside companies way more practical.

It’s still early, and there are rough edges, but the trajectory is clear: all-in-one platforms that merge app building and automation are coming fast — and Agent 3 is one of the first serious glimpses of that future.
