Summary
- Manny and Raymmar opened the doors at HQ for a two-hour behind-the-scenes look at our team, the energy after launch, and what Agent 4 actually means for builders.
- Manny demoed a taste-development app built in Agent 4 with a landing page, web app, and mobile-native version all inside one unified project on the Infinite Canvas.
- Raymmar showed Replitopolis, a live 3D city pulling from our BigQuery data where every building is a real user and every orange glow is a commit.
- Eight other team members joined the stream, from designers and engineers to our marketing team and Amjad, our CEO and co-founder.
Last week was Agent 4 launch week, and the team could finally breathe. Our very own community managers Manny Bernabe and Raymmar Tirado decided the best way to mark it was to bring the community inside HQ: pull teammates on camera, share what everyone has been building, and have fun along the way.
Big takeaway: Agent 4 changes how you build apps with others, making it easier (and more collaborative) than ever with Infinite Canvas, parallel tasks, and unified builds.
To give you a peek behind the current, and get you excited about what you can do with Agent 4, we’ll do a break down with Manny, Raymmar, and eight other Replit team members.
Manny Bernabe is building “Taste” with Replit
Manny opened with something personal. As a data scientist, he'd always felt like taste was out of reach. He kept hearing the same phrase: taste is the new moat. If anyone can build anything, what actually separates good work from everything else?
His answer: use AI to coach him through it.
He built a taste-development app in Agent 4 that lets you drop in an image or screenshot, sends it to Google Gemini for analysis, and returns a breakdown of typography, color palette, layout, and visual hierarchy. It also generates a reusable style prompt you can drop into any new Replit build to replicate what you liked.
On the Infinite Canvas, he had three separate artifacts in one project: the landing page, the full web app, and a mobile-native version running on his phone. He held the phone up to the camera, captured a photo live, and it appeared in his web library a few seconds later. One backend. One canvas. Web and mobile together.
He also showed variant generation. After building an initial personal site from a captured inspiration, he had Agent 4 spin up three variations: warm and intimate, dense and formal, playful and electric. Each one was a full landing page, not just a hero image.
Manny put it simply:
"I have to be able to describe something that I want to AI and AI will do it, but I still have to learn that terminology of what I'm trying to build in order to get AI to follow that plan."
That's what the app is for. A library of real design references, analyzed and translated into prompts, so you can communicate with the agent like a designer would.
Raymmar’s Replitopolis and the case for company data
Raymmar Tirado (pronounced RYE-mar) had been building something different. He called it Replitopolis: a live 3D city that pulls read-only from our BigQuery data lake and turns user activity into something you can actually see.
Every building is a Replit user. Height reflects prompts sent or checkpoints committed. An orange glow means a commit just happened. Cars follow traffic rules. The city updates live.
He used the demo to walk through version control in Replit: restoring the project to a state from four days prior so viewers could see where the city started, then reverting cleanly back. Practical version control, shown in context.
The top builder in the leaderboard during the stream: 1,100 prompts and 232 checkpoints in a single day.
The bigger point: if you have read-only access to your company's data, you can build something real with it in Replit. No writing to the database. No risk. Just connectors into BigQuery, Databricks, or Snowflake, and the ability to build internal tools and visualizations that look the part.
"There's so much alpha for you being early with vibe coding within your company."
Tala: the creator program is open
Tala Awwad from our marketing team leads the creator program, and she joined the stream to share a quick update: you can now apply at replit.com/creators.
We work with creators across every format and platform: YouTube, TikTok, LinkedIn, Instagram, X, and across multiple languages. Our international community is large and growing fast. The Aura Globe on screen during the stream made that obvious, with hundreds of live pins lighting up from Romania to Dubai to Melbourne.
Zade: he designed Agent 4 using Agent 4
Zade Keylani has been focused on the agent workspace at Replit since before Agent 2 launched. His most pointed moment: his engineering handoff for Agent 4 wasn't a Figma file. It was a Replit prototype.
He built the entire Agent 4 design in Agent 4.
Every state, every screen, every admin panel — all in Replit. That meant he was finding and reporting real issues while building live. The product was, in a way, building itself.
On why the Infinite Canvas matters:
"Canvas is kind of how you think just as a person — like you lay things out on your desk, you write things out on a whiteboard. The way humans think is more spatial."
He also talked about what Canvas does to the stakes. Before, making a change felt risky. You'd ask the agent, it would update something, and you'd wonder if you'd broken what was working. Now you can generate a bunch of ideas, go with none of them, keep iterating, or branch off in a new direction. The pressure is off.
Where he sees this going: designers, writers, ops folks, and technical leads all contributing to one Replit project, each in their own thread, merging when they're ready.
Raina Saboo: launching Agent 4 with five people
Raina from our marketing team joined fresh off the launch. When Agent 3 shipped, our marketing team was two people. For Agent 4, we were five or six, plus a DevRel team that had also grown from one.
The challenge wasn't just communicating Agent 4. It was communicating it to everyone at once: first-time builders, power users who knew every nuance of Agent 3, and enterprise customers at companies like Databricks, Snowflake, Stripe, and Atlassian. All at the same time, with a funding announcement going out the same week and a brand refresh launching alongside it.
The frame that held it together: low floor, high ceiling. Easy enough for anyone to start. No ceiling on what you can build.
The night before launch, our enterprise and marketing teams built a complete enterprise demo from scratch. They needed it. They shipped it. The enterprise customers in our early access program gave us quotes, demos, and logo approvals in timeframes that normally take months.
"We have a big community and people are at different stages of awareness, exploration, and building with Replit — so how do we meet people where they are?"
Saboo's closing thought: the theme for Agent 4 was creativity on purpose. Agent 3 pushed autonomy. But autonomy without human direction only goes so far. Agent 4 was built around the idea that AI should multiply what people create.
One day, one to go
That's a wrap on part one, but we're just getting started. In part two of our "Live from HQ" series, co-founders Haya Odeh and Amjad Masad join the team to talk about the vision behind Agent 4, what it means for every builder on the platform, and the real-world results already proving it out. Don't miss it.
