Replit AI transforms how you build software with Agent, an AI-powered development assistant that allows you to build entire applications in minutes, without knowing how to code.

​
How Replit fits together

Everything in Replit revolves around Agent, the AI orchestrator that ties the platform together. Agent coordinates your Workspace, Apps, Storage, and Integrations so you can focus on describing what you want to build.

Agent orchestrates all four pillars so you can focus on what to build
Workspace
Your cloud development environment. Agent reads, writes, and manages files, runs terminal commands, and uses language tools — all without leaving the browser.
  • -Full IDE with file editing and LSP diagnostics
  • -Integrated terminal for commands and scripts
  • -Workflows to manage long-running tasks
Apps
Build and ship full-stack applications. Agent configures dev servers, manages builds, and publishes to production with TLS and custom domains.
  • -Live preview updates in real-time as Agent works
  • -One-click deploy with automatic TLS certificates
  • -Supports React, Next.js, Flask, Express, and more
Storage
Persistent data layer. Agent provisions PostgreSQL databases, defines schemas with Drizzle ORM, and manages migrations — all from natural language.
  • -Built-in PostgreSQL with automatic provisioning
  • -Object storage for files, images, and assets
  • -Type-safe schemas shared across the stack
Integrations
Connect to external services without managing API keys manually. Agent discovers and configures integrations for auth, payments, and more.
  • -Pre-built connectors for Stripe, GitHub, Slack
  • -MCP servers extend Agent with custom tools
  • -OAuth and credentials managed automatically
  • Agent orchestrates the entire workflow — from generating code to setting up databases and deploying your app.
  • Workspace is your browser-based IDE where you and Agent write, debug, and preview code.
  • Apps are the projects you build and publish — Agent handles the code, configuration, and deployment.
  • Storage covers databases (SQL, key-value) and object storage (files, images) that Agent provisions automatically.
  • Integrations connect your app to external services like Stripe, APIs, and MCP servers.

​
Getting started

The fastest way to experience Replit AI is to create your first app with Agent:
  1. Start with Agent: Follow the Create with AI quickstart to build an app from scratch
  2. Choose your build mode: Select Lite for lightweight apps or prototypes (~3-5 mins) or use the default full build for a thorough implementation of your request (~10+ mins)
  3. Experience Agent 3’s autonomy: Customize Agent’s Code Optimizations while it tests itself with App Testing
  4. Set up billing: Configure usage alerts and budgets to control your AI spending
Agent is a premium feature that charges your Replit account based on usage. For pricing information and billing policies, see Replit AI Billing.

​
Accessing Agent

You can access Agent from any Replit App:
  • Tools dock: Find Agent in the left sidebar of your Workspace
  • Create new app: Start with Agent directly from the “Create a new App” screen
Agent is now available on all projects. Use General Agent to work with any framework or project type, including existing apps and Developer Framework templates.

​
Key capabilities

Agent offers powerful features that revolutionize your development workflow: Complete app generation
  • Natural language descriptions become functional applications
