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:

"The intoxicating delight of sudden understanding"1 best describes what I felt the first time I derived the Y Combinator (guided by the Little Schemer book). Learning Lisp (by way of Scheme) is how I first came about Paul Graham's essays. Which was, of course, a gateway drug to startups.

Since then, Y Combinator (the company) has touched my life in so many ways. Jessica Livingston's book Founders at Work demystified startups and humanized founders for me -- suddenly starting a Silicon Valley startup seemed more approachable. My first job at a startup in the U.S was at Codecademy, a YC company, where I joined right after they graduated the summer 2011 program. And Hacker News has been daily reading for me for years; it's where I get exposed to new ideas and technologies and where I get feedback and exposure on my projects.

Naturally, when I was thinking about taking the leap to start a startup, YC was top of mind. So I applied to open office hours to get feedback and see if our idea was something they'd back. Unfortunately, that particular meeting didn't go very well. The YC partner I met had the feedback that an online REPL is not really a startup -- it's just a fun toy -- and that instead, I should join another company building a superficially similar technology. But I've been waiting for someone to start this startup for years -- a website where people can not only learn how to code but can also build, collaborate with others, and ship software. In 2016 nobody seemed to be coming close to creating this.

Unfazed, my cofounder Haya, who's a designer and also my wife, and I decided to quit our jobs and pursue the startup. We allocated $20k to help get it off the ground while we find a revenue model or until we raise money. We worked out of our home in Foster City and was able to monetize the service early-on by selling our code evaluation infrastructure as an API. However, the free service was always growing faster than our revenue, and it didn't seem like we were going to break even on this business model.

I didn't think we would be able to raise money. In early 2016, some of my founder friends were struggling to raise capital, and I thought we'd fare no better since our startup is at the intersection of two industries -- devtools and edtech -- that have comparatively yielded minimal returns to VCs. Fortunately, someone took a chance on us. Roy Bahat, who heads up Bloomberg Beta, and whom I've met during my time at Codecademy decided to back us. With their stamp of approval, we were able to raise a comfortable seed round (or what's now probably called a pre-seed round). Around the same time, we got our first YC application rejection.

Rejected Then Recruited: Our Journey into Y Combinator

At Repl.it our mission is to make programming more accessible. We can’t do this alone so it’s great to partner with non-profits and hack clubs that share our mission. Re-coded is one of those non-profits, they're teaching programming in the refugee camps in Iraq and Turkey. Today I’d like to share with you their story of how they found Repl.it useful in overcoming logistical challenges.



By: Gabe Jackson

At Re:Coded, it’s our goal to provide a world-class education to refugees and displaced persons who would not otherwise have access to such opportunities.

In making that goal a reality, we depend on a number of tools in the classroom. One of our favorites is repl.it, an in-browser IDE and REPL that we use for everything from facilitating our selection process to live coding through examples in class to creating personalized homework assignments for students.

Teaching refugees how to code

Like any other startup, we go through ups and downs. However, we try to keep a positive energy, and you, my friends, contribute to that by sending your love, support, and thanks everyday. Above all, you inspire us with stories of how our product helped you learn, teach, and even develop a new skill to land a better job.

Today I’d like to share with you two stories from two Replers: Ruslan a software developer from Scotland, and Mark a math teacher from Houston.

Landing a self-driving job

Ruslan (@kuddai), a Physics Major, wanted to land a job in doing software engineering. So he spent a lot of time practicing coding using Repl.it and eventually was able to land a new job software engineering job in the cutting edge field of self-driving! Here is him telling the story:

While I was doing my M.S. in Informatics at University of Edinburgh, I realized that I lacked practice in coding interviews because my first major is in Physics. During my preparation (“Cracking coding interview”, “Algorithms by Robert Sedgewick”, hackerrank, etc.) I needed some general place to store my solutions for coding exercises. Eventually, I have chosen repl.it because:

 

Two Stories from Our Community

We're excited to launch this new part of our site.[](preview end) First, we have a place to share with you all the exciting features we're building (things that don't fit in a 140 characters and a GIF). You can also look forward to posts sharing what we learn in engineering and design.

Second, we're putting all the informational pages for our product and company here. This way you don't have to download tons of JavaScript that is intended for the development environment when all you want to do is read words. That'll also make it easier for Google to index our stuff.

For now, you can check out our new about us page, sign up for our classroom product beta, or checkout our new languages landing pages.
