AgentUI

Visual workflow builder for computer vision and AI. Create image processing pipelines by connecting tools in a drag-and-drop interface, then export and run them programmatically.

Part of the Datamarkin ecosystem - Built on PixelFlow and Mozo for production-ready computer vision.

What It Is

AgentUI is a web-first tool builder that lets you:

• Build visually: Drag and drop tools on a canvas to create workflows
• Connect tools: Wire outputs to inputs with type-safe connections
• Execute: Run workflows in the browser and see results instantly
• Export: Save workflows as JSON for version control and programmatic execution
• Integrate: Use as a Python library in your own applications

Think of it as a visual programming environment for computer vision tasks.

Quick Start

# Install
pip install agentui

# Start the server
agentui start

# Open http://localhost:8000 in your browser

That's it. The UI is already bundled - no separate build step needed.

What You Can Build

ML-Powered Tools

• Object Detection: Detect objects using YOLOv8 or Detectron2 (80 COCO classes)
• Instance Segmentation: Get pixel-level masks for detected objects
• Depth Estimation: Generate depth maps from single images (Depth Anything)

Image Processing

• Transforms: Rotate, flip, crop images with automatic detection coordinate updates
• Enhancement: CLAHE enhancement, auto-contrast, gamma correction, image normalization
• Analysis: Color analysis, quality metrics, dominant color extraction
• Blending: Combine multiple images with alpha blending

Annotation & Privacy

• Draw Detections: Bounding boxes, labels, masks, polygons
• Privacy Protection: Blur or pixelate regions automatically
• Object Tracking: Track objects across video frames
• Zone Analysis: Monitor object presence in defined areas

Input/Output

• Load: Images from files or base64 data
• Save: Export processed images to disk
• Web Display: Convert images to base64 for browser display

Usage

Web Interface

1. Add tools: Drag tools from the left palette onto the canvas
2. Connect: Click and drag from output ports to input ports
3. Configure: Select a tool to edit its parameters in the right panel
4. Execute: Click "Run Workflow" to process
5. View Results: See outputs in the results panel
6. Export: Save your workflow as JSON

Programmatic Usage

from agentui import Workflow

# Load a workflow created in the UI
workflow = Workflow.load('my_workflow.json')

# Run with an image
result = workflow.run(image='test.jpg')

# Access outputs
detections = result['detections']  # PixelFlow Detections object
print(f"Found {len(detections)} objects")

# Batch processing (automatic)
result = workflow.run(image=['img1.jpg', 'img2.jpg', 'img3.jpg'])
for i, dets in enumerate(result['detections']):
    print(f"Image {i}: {len(dets)} objects")

Workflow Design Philosophy

AgentUI is designed for visual workflow creation:

• Create workflows using the drag-and-drop UI
• Export as JSON for version control
• Load and execute programmatically with the Python API

Why not build workflows in code? The visual interface is the fastest way to prototype CV pipelines. The Python API focuses on execution (loading and running workflows), not construction. This separation keeps the codebase simple and the workflow format UI-native.

The Datamarkin Ecosystem

AgentUI integrates two powerful libraries:

• PixelFlow: Computer vision primitives (annotation, tracking, spatial analysis)
• Mozo: Universal model serving (object detection, segmentation, depth estimation)

These libraries are maintained by the same team and designed to work together seamlessly.

Development

UI Development

Only needed if you're modifying the UI:

cd ui
npm install
npm run dev  # Development server with hot reload at http://localhost:5173

# When done
npm run build  # Builds to ../agentui/static/

Adding Custom Tools

Tools are Python classes that inherit from Tool:

from agentui.core.tool import Tool, ToolOutput, Port, PortType

class MyCustomTool(Tool):
    @property
    def tool_type(self) -> str:
        return "MyCustomTool"

    @property
    def input_ports(self) -> Dict[str, Port]:
        return {"image": Port("image", PortType.IMAGE, "Input image")}

    @property
    def output_ports(self) -> Dict[str, Port]:
        return {"image": Port("image", PortType.IMAGE, "Output image")}

    def process(self) -> bool:
        image = self.inputs["image"].data
        # Do something with the image
        self.outputs["image"] = ToolOutput(processed_image, PortType.IMAGE)
        return True

Tools are automatically discovered by the registry. See CLAUDE.md for detailed development guidance.

Installation for Development

git clone <repository-url>

# Optional: UI development (only if modifying Svelte code)
cd ui
npm install
npm run build

Roadmap

Future additions will focus on:

• Vision-language models (GPT-4V, Claude, Gemini, Qwen-VL)
• Cloud storage integrations (S3, GCS, Azure)
• Advanced tracking and analytics
• Real-time streaming workflows
