AI agents can prototype apps… But shipping real software takes hours of testing, debugging, and refactoring. Agent 3 is 10× more autonomous — it keeps going where others get stuck. The “Full Self-Driving” moment of software.

Sep 10, 2025 · 3:31 PM UTC

Automated Testing. While building your app, Agent 3 will periodically test it using a browser, generating a report and fixing the issues it finds. Our proprietary testing system is 3x faster and 10x more cost effective than state-of-the-art Computer Use Models.
Longer Autonomous Runs. Agent 3 is 10x more autonomous than V2, capable of handling much more complex builds by detecting and fixing errors on its own. You can track the progress of your build with Live Monitoring on your phone, freeing you up to focus on other creative work.
One more thing. Agent 3 can now generate your own agents. Agents that can work with you in Slack or Telegram. Or run based on schedule or trigger based on webhook events. Enrich it with your own data sources, and build automations with apps like Notion, Linear, Dropbox, etc.

Autonomy and over-zealousness are not the same. Agent 3 does things that are totally unrequested while providing very misleading feedback when literally attempting to merge two projects, with similar file structures, that were made with earlier versions of agent. My experience differs from what you suggest here. I've been sent round in counter-intuitive loops only to determine agent analysed, planned and agreed a course of action then did something very different. This is very hard to manage as it doesn't communicate this with clarity and claims to have done something else. "Looking at the entire chat history, here are the things I did that differed from your specific and explicit requests: [...] The core issue: I overcomplicated what should have been a straightforward integration of working code by introducing my own solutions instead of following the original working [..] implementation."

Is it on a new project? Be curious if you can compare and contrast vs existing project.

A really cool innovation you could bring to Replit: "skin in the game" pricing :) (cc @nntaleb). I am currently watching Agent 3 testing, and changing code, probably burning through a lot of tokens and wondering "is it all worth it?". I'd be ofc more than ok to pay for fixes :)

Here’s some skin in the game: Try other products see if you find anything better for you. You can also download your code and take it elsewhere :)

I do not know how to code. Using Agent 3 I was able to create this website in 5 hours and spent $20.40 on usage credits. The future is here - Thank you Replit👏

How is the security? Is it able to help customers set up secure databases and payment systems?
