Use this interactive demo to learn how to integrate Replit with Claude Code.

This tutorial shows how to connect Claude Code to a Replit project using the Claude Agent SDK, so you can build and run automated AI agents without leaving your workspace.

Notes:

You need a Replit account and an Anthropic API key to follow this tutorial. Get your API key at console.anthropic.com.
See How to Integrate Replit with Claude for setting up a basic Claude connection first.

Sign in at replit.com and open the project you want to add Claude Code to, or click + Create Something New to start a fresh one.
In the Agent prompt field, describe the automated workflow you want to build and mention Claude directly - for example: Build an automated report summarizer for NEPS Corp that takes a list of weekly updates and returns a structured summary using Claude. Click the Arrow button to run.
The Agent generates your project files and sets up the Claude Agent SDK connection using your stored ANTHROPIC_API_KEY. Wait for the build to complete.
Your Anthropic API key is stored in the Secrets pane as ANTHROPIC_API_KEY. If you've already set this up from a previous Claude integration, it's available automatically across all your projects.
Click Run to launch your app. Test it in the Preview tab - for example, mention a set of weekly team updates and confirm Claude returns a structured summary output.

📌 Why this matters

Claude Code as a library gives you the same reasoning and automation capabilities that power Claude's own agentic workflows - packaged in a way you can deploy and schedule directly on Replit. For teams that handle repetitive document-heavy tasks like report generation, data summarization, or content review, this means turning a manual process into something that runs automatically on a schedule. Building it on Replit keeps everything in one place: the code, the credentials, the deployment, and the testing environment. Once it's running, the same agent can be handed off to anyone on the team without requiring them to set up a local environment.
