Agent Modes

Vibecode has 3 main models. Build, Plan, Auto.

Build Mode

Build Mode is where you bring your ideas to life and shape your app directly inside the Vibecode environment.

Unlike Plan Mode, Build Mode is hands-on and actively updates your project as you make changes. This is perfect for implementing new features, adjusting your app’s structure, and seeing your progress in real time.

You can use Build Mode to create and customize your app’s logic, UI, and integrations as you go. As you update and experiment, your edits are immediately applied to your project.

Build Mode is best for:

• Creating and editing features

• Adjusting or expanding your design

• Connecting your app to APIs and data sources

• Making real-time improvements

• Testing changes instantly in your app

Build Mode gives you direct control. When you’re ready to build, this is where you make it happen.

Plan Mode

Plan Mode helps you think through problems, debug issues and plan your product directly within the Vibecode app.

Unlike Build mode, Plan mode is conversational and can’t make changes to your project.

This is great for asking questions, planning your project, and debugging.

Plan mode can still reason across multiple steps and decide when to search files, inspect logs and more. If you ask it for help with implementing a functionality or troubleshooting it will come up with a step-by-step plan to reach your desired outcome.

Best ways to use plan mode:

• Debugging your app

• Planning how you want to set up your database

• Talking about new features

• Asking how to make improvements

• How new features will effect current functionality

Auto Mode

Auto Mode is the most agentic mode in VibeCode. Unlike Build Mode, which auto-generates code to build your app based on your specs, or Plan Mode, which helps you get clarity before making changes, Auto Mode lets the agent decide what actions to take on its own.

You just state your goal, and the VibeCode agent determines what needs to happen—planning, building, or both—then executes the steps automatically to move your VibeCode app forward.

It’s hands-off, high-autonomy creation that leverages the full intelligence of the agent to get things done.
