Wed, Dec 31, 20252025: Replit in Review
2025 was our biggest year yet. We shipped hundreds of features that made building faster, more accessible, and more powerful - from foundational Agent functionality to Design Mode, Fast Build, & an expanded Free Tier. Here's what shipped at Replit in 2025: Replit became Agent-first: Replit Agent was first released in September of 2024, but 2025 saw the platform orient itself around Agent. Replit is still a powerful place to write code, but the platform is now Agent-first and friendly for all builders. Agent evolved: Agent v2 (February), Agent 3 (September), and Design Mode (November) delivered 2-3x speed improvements throughout the year. Agent now tests itself, works for 200 minutes autonomously, and builds other agents.

Wed, Dec 17, 2025Inside Replit’s Snapshot Engine: The Tech Making AI Agents Safe
How Replit's snapshot engine makes AI agents safe: instant filesystem forks, versioned databases, and isolated sandboxes enable reversible AI development. Introduction At Replit, we’ve built a compute and storage fabric that allows us to make changes in an isolated, reversible way, almost like time travel. Envisioned initially to make Replit more powerful for professional developers and team collaboration, these primitives enable developers to experiment more frequently and faster, thanks to the speed at which they can clone a compute environment and start making changes to it. Later, when we built Replit Agent in 2024, we realized that the same primitives could superpower coding agents: not only does the system help the human driving the Agent, but the Agent itself also greatly benefits from these tools! One motivating example we discovered early in the development of Replit Agent is that giving an AI Agent direct access to your code and database can be risky: it might make a change you don’t like, or drop or alter your database in irreversible ways.
Tue, Dec 16, 2025Replit Learn Launches
Technology is moving so quickly that it can be hard to keep up. New tools, new techniques, and new possibilities in AI emerge every week. Somewhere between the hype and the jargon, it's easy to feel left behind. That's why we built Replit Learn, a free educational platform that teaches you how to build apps with AI. No coding experience required. Just clear, practical lessons that help you understand what's actually possible and how to do it yourself. What Is Replit Learn?
Mon, Dec 15, 2025Enabling Agent 3 to Self-Test at Scale with REPL-Based Verification
How Replit built a novel REPL-based verification system that combines code execution with browser automation to catch "Potemkin interfaces" (features that look functional but aren't), enabling Agent 3 to work autonomously for 200+ minutes. In 1783, Russia annexed Crimea from the Ottoman Empire. With war looming, the Russian Empress embarked on a six-month trip with several foreign ambassadors to garner more support. Grigory Potemkin, the minister responsible for rebuilding the region, realized the Empress and her visitors would never actually go ashore. He devised a scheme to hide the war-torn landscape by constructing "mobile villages." His men would dress as residents when Catherine's barge arrived, then disassemble the village after it left. Potemkin realized it was much cheaper to create the illusion of a vibrant town than to actually build one. If the people looking at the output don't look that close, why do more work than you need to?
Tue, Dec 9, 2025Building Production-ready Apps with Automated Database Migrations on Replit
Audience: Programmers and Engineers Skill level: Intermediate Introduction Separating development and production databases is fundamental to safe software development - it prevents accidental data loss, allows developers to test changes freely, and ensures production data remains stable and secure. Yet managing database changes between environments can be hard at the best of times, even sometimes for us engineers. Now imagine replacing the engineer with an AI agent, operating on behalf of a user who may not be aware of why having separate development and production databases is important or what a database migration even is - that’s when things get interesting. At Replit these are the types of challenges we strive to solve on a day to day basis. And managing database changes between environments seamlessly, safely and with as little user intervention as possible, was one of our most recent.
Tue, Dec 9, 2025Introducing Race to Revenue to Support the New Generation of Builders
TL;DR: We're giving 20 builders Replit credits, plus an 8-week program, a live CEO Showcase, and strategic perks — with zero equity required. Applications open December 9th. The best businesses being built today don't all follow the same playbook. While venture-backed startups chase unicorn outcomes, there's a parallel universe of builders creating profitable, sustainable businesses. Micro-SaaS products serving niche markets. Bootstrapped companies solving real problems. Solo founders turning side projects into full-time revenue. These builders don't need permission. They don't need to pitch stuffy suits. They just need the right tools, support, and community to accelerate what they're already doing. That's why we're launching Race to Revenue. What is Race to Revenue?

Wed, Nov 19, 2025Data Connectors
Introducing Enterprise Data Warehouse Connectors Build Data Apps with Agent in Minutes Today, we’re excited to roll out native data warehouse connectors for Snowflake, Databricks, and BigQuery, now available to all Replit Enterprise customers. Over the past year, data applications have become some of the most commonly built Enterprise applications on Replit. But until now, teams have lacked something fundamental: direct, secure, first-class connectivity to their data warehouses. Builders have resorted to workarounds—storing credentials as secrets, teaching the Agent how to connect, manually configuring database clients. These solutions worked, but they added friction, created security risks, and slowed down the development of tools that should have been effortless to build. With this launch, that changes.
Wed, Nov 19, 2025Fast Mode
Introducing Fast Mode: Instant, Precise Control Over Your Agent Today, we’re excited to launch Fast Mode, the fastest way to guide the Agent to perform quick changes with precision. And it's free for a limited time for all Replit users! For all the times you’ve thought “I just want to fix this one thing quickly”, Fast Mode is here. Why We Built It As Replit Agent has become more autonomous, users told us they loved the power, but missed the simplicity of small, targeted adjustments. Fast Mode bridges that gap.
Tue, Nov 18, 2025Design Mode
Introducing Design Mode Today, we’re launching a new Design Mode—the fastest way to go from idea → live website.
