Replit just launched Agent 3, and it changes everything for building apps with AI.
Here’s what’s new (and why it matters) 🧵
Meet @Replit: Idea to app, fast.
Create beautiful, modern web applications at the speed of thought with the power of Replit's AI Agent.
I redesigned a website in less than 5 minutes and transformed it into a professional one.
1. App Testing (self-testing apps)
Agent 3 can now test the apps it builds using an actual browser. It clicks, runs checks, and fixes issues—all by itself.
It's like having a built-in QA team on autopilot.
Longer Runtime (200 minutes)
Set your goals, hit run, and Agent 3 will operate autonomously for up to 200 minutes.
That’s hours of progress while you focus on something else.
Example I created with Replit: Stopwatch
2. Agents & Automations
Agent 3 isn't just for apps anymore. You can now build:
- Telegram bots
- Slack agents
- Automated workflows (daily reminders, custom tools, etc.)
Describe it in words, and the agent will build and deploy it for you.
3. Live Monitoring
Track everything in real time—even on your phone.
Monitor your project's progress without being tied to your desk.
Why This Matters
Replit Agent 3 marks the first instance where an AI can:
- Build apps
- Test them
- Fix bugs
- Ship automations
...all with 10x autonomy.
This isn't just about faster coding—it's software creation on autopilot.
Build. Test. Ship.
All on autopilot.
That’s Agent 3 → replit.com/agent3
