Replit Launches Agent 3, Its Most Autonomous AI Developer Yet
Key Takeaways: Agent 3 and Replit’s Breakthroughs
Replit unveiled Agent 3, its most autonomous agent to date, capable of working for up to 200 minutes without user input.
Agent 3 is 10x more autonomous than earlier versions, able to test, fix code, and build workflows for any industry task.
The company also closed a $250 million funding round, bringing its valuation to $3 billion, a near tripling since 2023.
Prysm Capital led the round, joined by Amex Ventures, Google’s AI Futures Fund, Coatue, a16z, and Y Combinator.
40 million users and $150 million in annualized revenue signal Replit’s rapid growth and global adoption.
Agent 3: A Leap Toward Autonomous AI Development
Replit, the agentic AI software creation platform, has launched Agent 3, describing it as a major step toward a "true collaborator" in autonomous coding. Unlike its predecessors, Agent 3 can run for 200 minutes of continuous work — compared with just 2 minutes for Agent 1 and 20 minutes for Agent 2.
The system is designed to act less like an assistant and more like a real developer teammate, capable of independently testing applications, fixing bugs, and optimizing workflows. Users can even watch Agent 3’s browser as it clicks through apps, checks buttons, runs APIs, and validates every feature.
Amjad Masad, CEO and co-founder of Replit, emphasized the company’s vision:
“With the raise and our new AI Agent, we are positioned to supercharge customer traction to become the standard for enterprises. The future is exciting with millions — if not billions — of people bringing their ideas to life with a few clicks.”
Replit reports that its proprietary testing system is 3x faster and 10x cheaper than existing computer-use models, enabling Agent 3 to continuously refine code in the background.

Prysm Capital led the round, joined by Amex Ventures, Google’s AI Futures Fund, Y Combinator, Coatue, a16z, Craft, and Paul Graham.
Jay Park, managing partner at Prysm Capital, said:
“Replit's vision — to empower everyone to build — strongly resonated with us. The traction with individuals, teams and enterprises has positioned Replit to be the leading agentic AI platform.”
