What is Rork's Backend Capabilities?

Rork provides an optional backend infrastructure for applications requiring server-side functionality. Currently in its beta phase, if you run into any issues, please reach out to Support.

Overview

The backend enables developers to implement custom server logic, API endpoints, and database operations within their Rork applications.

Capabilities

• API Endpoints — Define custom routes for client-server communication
• Server-Side Logic — Execute secure operations outside the client application
• Database Integration — Persistent data storage and retrieval
• Protected Routes — Authentication and authorization support

Technical Stack

Component	Technology
Server Framework	Hono
API Layer	tRPC

When to Use

A backend is recommended for:

• Social applications with user-to-user interactions
• Multiplayer or real-time collaborative features
• Applications requiring shared or centralized data storage

A backend is not required for:

• Single-user applications
• Local data storage use cases
• Applications utilizing only built-in AI features

AI Capabilities

To add AI capabilities to your application, use the Rork Toolkit. The Toolkit provides pre-built AI features including text generation, image creation, voice-to-text, and intelligent assistants—no backend configuration required.

What’s inside the Rork Toolkit?

Feature	Model	Provider
AI Assistant (Chat/Agent)	Claude Sonnet 4.5	Anthropic
Text Generation	GPT-5 Chat	OpenAI
Data Extraction (generateObject)	GPT-4.1	OpenAI
Image Generation	GPT-Image-1.5 (DALL-E)	OpenAI
Image Editing	Gemini 2.5 Flash Image	Google
Voice to Text	Whisper-1	OpenAI
Tool Result Summarization	Gemini 2.5 Flash	Google

The models are accessed through these toolkit SDK functions:

• Uses Anthropic Claude Sonnet 4.5 for chat and agentic workflows
• Uses OpenAI GPT-5 for text generation
• Uses OpenAI GPT-4.1 for structured data extraction
• Image generation uses OpenAI DALL-E
• Image editing uses Gemini 2.5 Flash Image
• Speech-to-text uses OpenAI Whisper-1

What you can build with the Rork Toolkit

The Rork Toolkit lets you build full AI-powered apps—chat agents, content generators, data extractors, image and voice features, and multimodal workflows—all from one toolkit. It’s everything you need to create smart, production-ready AI experiences without managing multiple models or providers.
