Core Concepts

Cloud-First Development

Replit Agent runs entirely in the cloud:

• No local development environment needed
• Instant startup
• Automatic dependency installation
• Built-in hosting

AI Integration

The Agent can:

• Generate code from prompts
• Modify existing code
• Debug errors
• Add features
• Refactor code

Examples

Python API

Create a REST API with Flask that has:
- GET /items - list all items
- POST /items - create a new item
- GET /items/:id - get a specific item

React App

Build a weather dashboard that:
- Shows current weather for a city
- Displays 5-day forecast
- Has a search bar
- Uses a free weather API

Best Practices

1. Start with clear prompts — Be specific about features and requirements
2. Use for prototyping — Move to local dev for production work
3. Leverage multiplayer — Collaborate in real-time with team members
4. Test incrementally — Verify generated code before adding features
5. Export when ready — Download code for local development

Troubleshooting

Issue	Solution
Agent not generating	Check prompt clarity and complexity
Build fails	Review error logs and fix dependencies
Deployment issues	Verify environment variables are set
Performance slow	Use simpler models for quick iterations
