Retool's new app builder

[retool_team]

A new AI-powered app builder is now available to cloud instances! Build production-ready React apps using natural language in the app builder or through your favorite coding agent via MCP. Whatever or however you build, everything inherits the security standards your organization has already approved and implemented.

The updated app builder is available in cloud instances. It will be available in upcoming stable and edge releases.

The app builder includes:

• A Chat tab where you describe changes in natural language and an AI agent plans and executes them, with file uploads and per-thread model selection.
• A Data tab that shows the resources connected to your app and the functions that interact with them, with optional approval gates on writes.
• A Code tab that lets you view and edit every file your app uses.
• Support for organization themes, third-party npm packages, and publishing and version history.

Apps run on React 19 and a curated set of supporting libraries.

Apps built using Retool's drag-and-drop IDE are now called classic apps. Apps refer to apps created in the new app builder.

For the new app builder how do you connect a resource? the @ tag does not surface the resource I am looking for

Hey @Antony_Kariu! Welcome to the community.

What kind of resource are you trying to tag? Some legacy resource types such as OpenAPI aren't supported in the new app builder.

Ah got it - this is one of the resource types that isn't yet supported in the new builder. We are definitely planning on it, though! I've logged your interest in the relevant tracking ticket and will give you an update as soon as I can.
