The Replit Team

Introducing Agent 4 — our fastest, most versatile Agent yet. It's built around a simple idea: you should spend your time creating, not coordinating. Agent 4 takes on the tedious-but-necessary work in the background so you can stay in creative flow and ship production-ready software 10x faster. Because Replit is where software is built, run, and shipped — all in one place — Agent 4 can handle both the complex and the mundane, so you can focus on what's uniquely human: creativity.

Summary

Agent 4 is built on four pillars designed to keep you in creative flow and ship production-ready apps 10X faster.

Design Freely: Generate design variants on an infinite canvas, tweak them visually, and apply the best one directly in your app.

Move Faster: Tackle auth, database, back-end functionality and front-end design all at once with parallel agents, with progress across tasks clearly visible. Once done, tasks can be merged seamlessly into the main app.

Ship Anything: Create mobile and web apps, landing pages, decks, videos and more in the same project, with shared context and design so you can scale efficiently.

This is part 2 of a 6-part series we’re running about how product managers are using AI tools and vibe coding. Written by and for product managers.

Summary

Traditional prototyping workflows cost PMs weeks per round-trip, delaying the user signal that only working software produces.

Every handoff to design, engineering, and QA introduces translation loss that compounds before a prototype reaches testing.

AI-integrated workflows cut translation points by generating interactive prototypes directly from a behavioral brief you write.

This is part 1 of a 6-part series we’re running about how product managers are using AI tools and vibe coding. Written by and for product managers.

Summary

AI tools for product managers now operate across two layers: a productivity layer and an expanded capability layer.

Writing tools like Claude, Notion AI, and Grammarly help you draft PRDs and condense research into clear summaries faster.

Research tools like Dovetail and Perplexity surface patterns across interviews and feedback, making continuous discovery more manageable.

This post recaps part 2 of our "Live from HQ" livestream series covering the Agent 4 launch.

Peter engineered Agent 4's parallel task system, enabling AI to resolve merge conflicts automatically 90% of the time.

Haya Odeh, co-founder and design lead, built the Infinite Canvas to close the gap between design and engineering.

Jacob's collaboration features give builders real-time visibility into who's working on what inside a shared project.

Adi made branching feel instant using micro VMs, creating isolated task environments that spin up in seconds.

Live from Replit HQ Part 2

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.

Live from Replit HQ: Agent 4 Launch Pt. 1

How the Replit you already know just got a whole lot better.

Summary

Replit Agent 4 meaningfully evolves four core pillars of the building experience: design, collaboration, what you can build, and how you plan and build.

Design Mode has been replaced by the Design Canvas—an infinite board that supports all artifact types, live previews, and direct manipulation tools.

The old fork-and-merge collaboration model is gone; teammates now work together in a single shared project with agent-assisted merging.

The plan-then-build workflow has evolved into plan-while-building, so you can keep moving forward without waiting for one stage to finish before starting the next.

Agent 4 isn't just about what's new. It's about how the tools you've already been using have been rethought from the ground up. Each feature has been meaningfully evolved in Agent 4, not replaced, and the result is a building experience that's faster, more collaborative, and less frustrating.

What’s changed from Replit Agent 3 to Agent 4

Summary

Manny (from Replit), and Cong & Denis (from Databricks) walked through our new Replit–Databricks connector, showing how we vibe coded enterprise data apps live.

Databricks centralized enterprise data and AI for tens of thousands of customers, so our Replit apps could tap governed tables, models, and warehouses without copying sensitive data around.

We used Replit’s Databricks connector to pull real sample datasets into an app, then let the agent vibe code a 3D weather globe that stayed safely inside Databricks.

Replit Agent handled the scaffolding and UI while Databricks handled scale and governance, so Manny could ship a working data tool in minutes instead of weeks of traditional BI work.

Databricks Genie acted as an in-app data copilot, answering natural-language questions with cited tables so builders saw exactly which data every insight came from.

Replit raises $400 million at a $9 billion valuation

In 2016, we started Replit with a simple but radical belief that anyone should be able to build an app without ever learning to code. Our vision was for software to expand human imagination. Instead of requiring people to master software as it existed, we believed software could evolve to meet people where they are, translating their imagination into reality.

At the time, this idea felt almost impossible. Software development was for engineers, not students, teachers, designers, or small business owners. The tools were complex, required specialized training, and thus inaccessible to most of the world. The terms vibe coding and AI agents were still nearly a decade away.

Fundamentally, we believe the future of technology is deeply human. As software adapts to people, billions will be able to turn their ideas into reality without needing to understand or be restricted by the machinery underneath. AI will unlock human creativity, kicking open a world where far more people can build, experiment, and create than ever before.

This vision is fast becoming reality – and we are about to accelerate faster than ever. Replit has raised $400 million, valuing the company at $9 billion, a 3x increase in just six months, reflecting the strength of our business and growth still to come.

Summary

Designer turned builder Ruth Heasman ships Spookseek AR for Replit’s mobile Buildathon, turning a Halloween AR idea into a real iOS game.

She builds for mobile first, leaning on camera, motion sensors, haptics, sound, and AR visuals so ghost hunting feels grounded in the real room.

Replit Agent helped her co-create a bespoke 3D system, even though she started “really clueless” about 3D math and AR stacks.

Together they worked around Expo’s lack of ARKit, projecting ghosts on a virtual sphere and tuning targeting through a lot of iteration.

The hardest work lands in the last twenty percent, when dev and production builds behave differently and performance problems fail silently.

How Replit turns any web page into a deterministic video by virtualizing time itself, patching key browser audio APIs, and waging war against headless Chrome's quirks.



The Problem: Browsers Don't Want to Be Cameras

Here's a deceptively simple product requirement: take a web page with animations, and turn it into a video file.

Sounds easy, right? Open a browser. Record the screen. Export MP4. Ship it.

We tried that. It doesn't work.

The core issue is that browsers are real-time systems. They render frames when they can, skip frames under load, and tie animations to wall-clock time. If your screenshot takes 200ms but your animation expects 16ms frames, you get a stuttery, unwatchable mess. The browser kept rendering at its pace while we captured at ours, and the two never agreed.

We Built a Video Rendering Engine by Lying to the Browser About What Time It Is

We’ve heard from builders that it hasn’t always been obvious which plan is right for them. The truth is, we’re seeing more distinct kinds of builders on Replit than ever before — from people just getting started, to teams shipping serious production projects.

That’s why we’re making our plans clearer and more purpose-built.

Replit Pro is our most powerful plan yet, built for serious builders who want to push their projects further with the best Agent experience and premium benefits.

At the same time, we’re making it easier to get started with Replit Core — with better collaboration features, a lower price, and new controls that help you manage costs. If you’re getting started or building casually, Core is for you.

Summary

New Pro plan ($100/month). Access to powerful Agent modes, tiered credits with discounts, priority support, up to 15 builders, credit rollover.

Replit Pro Is Here — and Core Now Offers Even Better Value

Summary

Host Manny talks with builder Dan Kempe and Replit designer Victoria Kim about shipping real iOS apps without a dev team.

Kempe explains how he built Flash News, a speed‑reading news app, for Replit’s mobile Buildathon.

They walk through how Replit Agent, Expo, and the new mobile tools make App Store deployment far less painful.

Victoria shares design advice for mobile: small‑screen constraints, haptics, and learning directly from Apple’s guidelines.

The group digs into mobile app marketing: using existing audiences, social platforms, and strong visuals to get early downloads.
