Replit — Unlocking a New Way to Build Enterprise Data Apps with Microsoft Fabric

We believe enterprise software should move at the speed of ideas.

Today, we’re collaborating with Microsoft to make it dramatically easier for enterprises to build AI-powered apps in Replit and deploy them directly into Microsoft Fabric with enterprise-grade governance and security built in.

The integration helps teams go from prompt to production faster- turning governed enterprise data into internal tools, dashboards, workflows, and AI applications in a fraction of the time traditional development requires.

Bringing AI-Native Development to the Microsoft Data Ecosystem

Microsoft Fabric is a unified platform for enterprise data, bringing together analytics, governance, storage, and business intelligence into a single environment. At the same time, Replit has emerged as one of the fastest ways to build software using AI-assisted development.

With the introduction of Rayfin, a new open-source SDK and CLI for building application backends, business teams can now go beyond simply connecting to data. They can define and deploy complete, production-ready applications directly on top of it. This enables a new workflow: applications can be described, generated, and deployed directly to Fabric, where enterprise data already lives.

The integration connects those two worlds.

“Organizations today want to move faster from data to impact without compromising on governance, security, or scalability. Our collaboration with Replit helps customers turn their Microsoft Fabric data into production-ready applications using AI-powered development workflows that dramatically simplify the path from idea to deployment. Together, we’re enabling enterprises to build a new generation of intelligent, data-driven applications directly within their existing Microsoft ecosystem.” -Arun Ulag, Executive Vice President, Azure Data at Microsoft.

Now, teams can use Replit’s AI-powered software creation platform to create applications that work natively with Fabric data and deploy directly into the Microsoft ecosystem. Instead of spending weeks wiring together authentication layers, APIs, deployment tooling, and governance policies, business teams can focus on describing the application they want to build while Rayfin defines the backend in code and Fabric runs it securely at scale.

From Data Access to Full Application Deployment

Basic integrations between development tools and enterprise data platforms often stop at connectivity. Business or data teams can access data, but still have to rely on developers to manually build and manage the surrounding infrastructure needed to turn that data into a production application. This includes implementing the required governance, compliance, and audit hooks demanded by enterprise IT.

This integration goes much further.

With Rayfin, applications built in platforms like Replit can be automatically scaffolded with a complete enterprise-grade backend, including data models, authentication, and access policies, and deployed directly into Microsoft Fabric. Deployment becomes part of a unified workflow rather than a separate infrastructure project.

That means:

Applications can securely connect to governed Fabric data sources
Authentication and enterprise access controls are built into the flow
Teams can deploy apps directly into their existing Microsoft data ecosystem
Developers avoid maintaining custom complex application infrastructure and deployment pipelines

The result is an end-to-end experience for building enterprise-grade data applications, not just another data connector.

“We appreciate how quickly we can build and iterate in Replit, but for some of our business, our data needs to stay governed and centralized in Fabric. With Rayfin, we finally have both—fast development in the tools we prefer, and the confidence that our applications run on top of our enterprise data platform. This is exactly what we’ve been looking for.”
— Cody Luth, AI Solutions Architect*,* Leatherman

What This Unlocks for Enterprise Teams

For organizations already using Microsoft Azure, this partnership creates a much faster path to building internal software, all while keeping governance, authentication, and security inside the Fabric environment they already know and trust.

Teams can rapidly create:

Department-specific productivity tools
Operational dashboards
Data exploration tools
Workflow automation apps
Reporting interfaces

Instead of exporting data into disconnected tooling stacks, applications can live alongside the organization’s existing Microsoft infrastructure.

For business teams, this means less time spent on setup and more time spent solving business problems.

For enterprise IT teams, it means maintaining centralized governance and compliance while still enabling rapid software creation.

AI Changes the App Development Workflow

The bigger shift is what this enables from a product-development perspective.

A business user can now:

Describe the application they want to build
Have Replit’s AI agent scaffold the application automatically
Use Rayfin to define the app’s backend servicesOptionally connect the app to existing enterprise data in Fabric via Rayfin connectors

Deploy and run within your organization’s Fabric tenant All within a single workflow.

That dramatically compresses the time between idea and published app.

What previously required coordinating across multiple systems: engineering teams, DevOps , and weeks of infrastructure setup can now be handled through a seamless, AI-assisted workflow that spans app development and production.

Customize Replit Agent with Skills & Custom Instructions

Every team has conventions. How you structure a project. How you handle secrets. Your design system, your testing standards, your code style. The problem: AI Agents don’t know your conventions. So you explain it again on every prompt, paste in your standards doc, or just hope someone remembered to add the context. It is one of those small frictions that compounds quietly until you are spending more time re-teaching the Agent than actually building. Today we're launching Agent Customization: a way to give Replit Agent the context it needs to work the way you or your team actually works, across all projects. It has two parts: Custom Instructions and Skills. Custom Instructions Custom Instructions are always-on guidelines injected automatically into the agent's context on every project, every session, before anyone types a single word. Write them once, and the Agent applies them to every project in the workspace, automatically. If you want the Agent to not commit secrets to version control, always use TypeScript strict mode, or follow your company's data handling policy — that goes in Custom Instructions. You don't ask each time. It just knows.

Package Firewall: Blocking 8,000+ malicious packages daily

Replit already scans your projects for vulnerable dependencies, and audits your dependencies before you publish. But risk shows up earlier than that, while you are developing, the moment a malicious package gets installed. Today we're launching Package Firewall, in partnership with Socket (a software supply-chain security company) . Package Firewall blocks malicious and compromised packages from ever being installed into your app, even while you are building. This network-level security protection eliminates any window for malware to be installed into your project. It's on by default for every builder, with nothing to set up. Since rolling out a week ago, Package Firewall has been blocking around 8,000 packages per day across builders on Replit. Over the course of a year, millions of vulnerable package installs will be blocked, leaving builders and their users safer: “Replit is helping define how the next generation of software gets built, with AI agents working alongside developers to create and ship applications faster. That makes install-time security more important than ever. By partnering with Replit, Socket is enabling builders to move quickly while keeping malicious packages out of the development workflow and stopping supply chain attacks before a single line of malicious code runs." — Feross Aboukhadijeh, CEO, Socket How it works When you or the Agent run an install command like npm install or pip install to install a new dependency, the request passes through Package Firewall. If the package is clean, the install runs as usual and you won't notice a thing. If Socket has flagged the package as malicious or compromised, the install is blocked before any code reaches your environment.

Build a custom Shopify storefront on Replit

Starting today, anyone can design and launch a custom Shopify storefront by chatting with the Replit Agent. Describe the store you want, and Agent generates a custom front end, creates a new Shopify store, and adds your products from the same conversation. When you're ready to sell, claim the store in Shopify, activate payments, and use Replit to deploy your storefront to a domain. From the first prompt to taking real orders is roughly ten minutes. Why we built this Replit builders already ship real software, from internal tools, to side projects, to full businesses. But selling physical products is different: managing physical inventory, fulfillment, tax compliance, shipping, and multi-channel selling. Shopify is the gold standard for that, powering retail businesses of every size. What was missing was a way to design a storefront for Shopify with the same conversational workflow Replit builders already use for everything else. That's what this integration adds: a beautifully designed front end generated from a prompt, with Shopify provisioned, configured, and managed from inside Replit itself. You describe what you want, and Agent builds it. The result is yours to refine, backed by Shopify's commerce infrastructure end to end. How it works Most of the experience happens inside Replit. You'll only need to visit Shopify once to sign in or create an account, claim your store, set up payments, and publish. After that, you can build your storefront, manage products, and run your store directly from Replit.
