The Replit Team

We’re excited to introduce Agent 3—our most advanced and autonomous Agent yet. Compared to Agent V2, it is a major leap forward. It is 10x more autonomous, with the ability to periodically test your app in the browser and automatically fix issues using our proprietary testing system—3x faster and 10x more cost-effective than Computer Use models. Even better, Agent 3 can now generate other agents and automations to streamline your workflows.

 

What’s New



1. App Testing: Agent tests the apps it builds (using an actual browser)

Agent 3 now tests and fixes the app it is building, constantly improving your app behind the scenes. We are launching two different options here, depending on your needs:

Introducing Agent 3: Our Most Autonomous Agent Yet

Bringing a new product idea to life often depends on resources that aren’t always readily available, like engineering time, staging environments, or internal tooling. But with the rise of software creation platforms like Replit, product managers now have more accessible ways to prototype working integrations on their own. When combined with Plaid’s APIs, these tools make it possible to build and share working demos often in just 30 minutes.

Whether you’re building a better onboarding experience or a streamlined loan application process, testing a new anti-fraud product, or exploring how to integrate account-level insights, prototyping with Plaid and Replit Agent makes it easy to validate ideas, get internal buy-in, and gather real-world feedback without engineering resources.



Why prototyping matters more than ever for PMs

As a product manager, your best ideas often live at the intersection of customer insight and product intuition. But moving from a hypothesis to something stakeholders can see and click on often means waiting on design or engineering resources.

Rapid prototyping flips this script. When you can show, not just tell, how your product idea might work with a Plaid integration, you accelerate alignment, sharpen product decisions, and unlock better feedback from both internal teams and customers.

SpotHero: Innovation through Rapid Prototyping

With Replit Teams, the SpotHero marketing team has developed internal tools, data integrations, and prototypes to seamlessly and cost-effectively integrate disparate departmental systems.

“Rapid prototypes that don’t tie up product and engineering teams with unproven methods are vital for innovation. Replit enables us to cycle quickly, helping us determine which projects are worthy of greater effort from our limited internal teams and which should continue to run departmentally.”

SpotHero overview

SpotHero is the leading parking reservation marketplace that helps drivers find, compare, and reserve parking across 300+ cities in the U.S. and Canada. Since being founded in 2011, SpotHero has helped drivers park over 75 million cars.


SpotHero: Innovation through Rapid Prototyping

Replit Teams transformed the SkillsEngine Product and Design team from a traditional no-code department to a prolific team that writes, shares, and ships code. In the process, the team unblocked engineering bottlenecks, improved prototype fidelity, shipped faster, and saved thousands of dollars and resources.

"I have tried every no-code tool and AI app. I have been coding for nearly 15 years now. Nothing has sparked the creative code output that Replit has for me. I have coded more in the past 12 months than the previous 10 years because it makes it so easy to get started and just try stuff. We can just focus on building ideas.” - Max Miner, Executive Director of Product and Design

SkillsEngine overview

SkillsEngine develops data services and tools for employers, educators, and workforce interests. Employers use SkillsEngine data to confidently assess their workforce capabilities and hiring needs. Educators use features like skill-based job profiles to plan curricula that meet current job market needs.
