adk-studio

Visual development environment for AI agents built with Rust Agent Development Kit (ADK-Rust).

Overview

adk-studio provides a visual, low-code development environment for building AI agents with ADK-Rust:

• Drag-and-Drop Canvas - Visual workflow design with ReactFlow
• Agent Palette - LLM Agent, Sequential, Parallel, Loop, Router agents
• Tool Integration - Function, MCP, Browser, Google Search tools
• Real-Time Chat - Test agents with live SSE streaming
• Code Generation - Compile visual designs to production Rust code
• Build System - Compile and run executables directly from Studio

Installation

cargo install adk-studio

Or build from source:

cargo build --release -p adk-studio

Quick Start

# Start ADK Studio server
adk-studio

# Open in browser
open http://localhost:3000

With Custom Host

# Bind to all interfaces (for remote access)
adk-studio --host 0.0.0.0 --port 8080

Features

Visual Agent Builder

• Drag agents from palette onto canvas
• Connect agents to create workflows (Sequential, Parallel, Loop)
• Configure agent properties: name, model, instructions, tools
• Add sub-agents to container nodes

Tool Support

• Function Tools - Custom functions with code editor and templates
• MCP Tools - Model Context Protocol servers with templates
• Browser Tools - Web automation with 46 WebDriver actions
• Google Search - Grounded search queries
• Load Artifact - Load binary artifacts into context

Real-Time Execution

• Live SSE streaming with agent animations
• Event trace panel for debugging
• Session memory persistence
• Thought bubble visualization

Code Generation

• View Code - See generated Rust code with Monaco Editor
• Compile - Generate Rust project from visual design
• Build - Compile to executable with real-time output
• Run - Execute built agent directly
