`daggr` is a Python library for building AI workflows that connect [Gradio](https://github.com/gradio-app/gradio) apps, ML models (through [Hugging Face Inference Providers](https://huggingface.co/docs/inference-providers/en/index)), and custom Python functions. It automatically generates a visual canvas for your workflow allowing you to inspect intermediate outputs, rerun any step any number of times, and also preserves state for complex or long-running workflows.

## Installation

```bash
pip install daggr
```

(requires Python 3.10 or higher).

## Quick Start

After installing `daggr`, create a new Python file, say `app.py`, and paste this code:

```python
import random

import gradio as gr

from daggr import GradioNode, Graph

glm_image = GradioNode(
    "hf-applications/Z-Image-Turbo",
    api_name="/generate_image",
    inputs={
        "prompt": gr.Textbox(  # An input node is created for the prompt
            label="Prompt",
            value="A cheetah the grassy savanna.",
            lines=3,
        ),
        "height": 1024,  # Fixed value (does not appear in the canvas)
        "width": 1024,  # Fixed value (does not appear in the canvas)
        "seed": random.random,  # Functions are rerun every time the workflow is run (not shown in the canvas)
    },
    outputs={
        "image": gr.Image(
            label="Image"  # Display original image
        ),
    },
)

background_remover = GradioNode(
    "hf-applications/background-removal",
    api_name="/image",
    inputs={
        "image": glm_image.image,
    },
    postprocess=lambda _, final: final,
    outputs={
        "image": gr.Image(label="Final Image"),  # Display only final image
    },
)

graph = Graph(
    name="Transparent Background Image Generator", nodes=[glm_image, background_remover]
)

graph.launch()
```

Run `daggr app.py` to start the app with hot reloading (or `python app.py` for standard execution). You should see a Daggr app like this that you can use to generate images with a transparent background!

## When to (Not) Use Daggr

Use Daggr when:
* You want to define an AI workflow in Python involving Gradio Spaces, inference providers, or custom functions
* The workflow is complex enough that inspecting intermediate outputs or rerunning individual steps is useful
* You need a fixed pipeline that you or others can run with different inputs

**Why not... ComfyUI?** ComfyUI is a visual node editor where you build workflows by dragging and connecting nodes. Daggr takes a code-first approach: you define workflows in Python and the visual canvas is generated automatically. If you prefer writing code over visual editing, Daggr may be a better fit. In addition, Daggr works with Gradio Spaces and Hugging Face models directly, no need for specialized nodes.

**Why not... Airflow/Prefect?** Daggr was inspired by Airflow/Prefect, but whereas the focus of these orchestration platforms is scheduling, monitoring, and managing pipelines at scale, Daggr is built for interactive AI/ML workflows with real-time visual feedback and immediate execution, making it ideal for prototyping, demos, and workflows where you want to inspect intermediate outputs and rerun individual steps on the fly.

**Why not... Gradio?** Gradio creates web UIs for individual ML models and demos. While complex workflows can be built in Gradio, they often fail in ways that are hard to debug when using the Gradio app. Daggr tries to provide a transparent, easily-inspectable way to chain multiple Gradio apps, custom Python functions, and inference providers through a visual canvas.

Don't use Daggr when:
* You need a simple UI for a single model or function - consider using Gradio directly
* You want a node-based editor for building workflows visually - consider using  ComfyUI instead

## How It Works

A Daggr workflow consists of **nodes** connected in a directed graph. Each node represents a computation: a Gradio Space API call, an inference call to a model, or a Python function.

Each node has **input ports** and **output ports**, which correspond to the node's parameters and return values. Ports are how data flows between nodes.

**Input ports** can be connected to:
- A previous node's output port → creates an edge, data flows automatically
- A Gradio component → creates a standalone input in the UI
- A fixed value → passed directly, doesn't appear in UI
- A callable → called each time the node runs (useful for random seeds)

**Output ports** can be connected to:
- A Gradio component → displays the output in the node's card
- `None` → output is hidden but can still connect to downstream nodes

### Node Types

#### `GradioNode`

Calls a Gradio Space API endpoint. Use this to connect to any Gradio app on Hugging Face Spaces or running locally.

```python
from daggr import GradioNode
import gradio as gr

image_gen = GradioNode(
    space_or_url="black-forest-labs/FLUX.1-schnell",  # HF Space ID or URL
    api_name="/infer",                                 # API endpoint name
    inputs={
        "prompt": gr.Textbox(label="Prompt"),          # Creates UI input
        "seed": 42,                                    # Fixed value
        "width": 1024,
        "height": 1024,
    },
    outputs={
        "image": gr.Image(label="Generated Image"),   # Display in node card
    },
)
```

**Finding the right inputs:** To find what parameters a GradioNode expects, go to the Gradio Space and click "Use via API" at the bottom of the page. This shows you the API endpoints and their parameters. For example, if the API page shows:

```python
from gradio_client import Client

client = Client("black-forest-labs/FLUX.1-schnell")
result = client.predict(
    prompt="Hello!!",
    seed=0,
    randomize_seed=True,
    width=1024,
    height=1024,
    num_inference_steps=4,
    api_name="/infer"
)
```

Then your GradioNode inputs should use the same parameter names: `prompt`, `seed`, `randomize_seed`, `width`, `height`, `num_inference_steps`.

**Outputs:** Output port names can be anything you choose—they simply map to the return values of the API endpoint in order. If an endpoint returns `(image, seed)`, you might define:

```python
outputs={
    "generated_image": gr.Image(),  # Maps to first return value
    "used_seed": gr.Number(),       # Maps to second return value
}
```

#### `FnNode`

Runs a Python function. Input ports are automatically discovered from the function signature.

```python
from daggr import FnNode
import gradio as gr

def summarize(text: str, max_words: int = 100) -> str:
    words = text.split()[:max_words]
    return " ".join(words) + "..."

summarizer = FnNode(
    fn=summarize,
    inputs={
        "text": gr.Textbox(label="Text to Summarize", lines=5),
        "max_words": gr.Slider(minimum=10, maximum=500, value=100, label="Max Words"),
    },
    outputs={
        "summary": gr.Textbox(label="Summary"),
    },
)
```

**Inputs:** Keys in the `inputs` dict must match the function's parameter names. If you don't specify an input, it uses the function's default value (if available).

**Outputs:** Return values are mapped to output ports in the same order they are defined in the `outputs` dict—just like GradioNode. For a single output, simply return the value. For multiple outputs, return a tuple:

```python
def process(text: str) -> tuple[str, int]:
    return text.upper(), len(text)

node = FnNode(
    fn=process,
    inputs={"text": gr.Textbox()},
    outputs={
        "uppercase": gr.Textbox(),  # First return value
        "length": gr.Number(),       # Second return value
    },
)
```

Note: If you return a dict or list, it will be treated as a single value (mapped to the first output port), not as a mapping to output ports.

#### `InferenceNode`

Calls a model via [Hugging Face Inference Providers](https://huggingface.co/docs/inference-providers/en/index). This lets you use models hosted on the Hugging Face Hub without downloading them.

```python
from daggr import InferenceNode
import gradio as gr

llm = InferenceNode(
    model="meta-llama/Llama-3.1-8B-Instruct",
    inputs={
        "prompt": gr.Textbox(label="Prompt", lines=3),
    },
    outputs={
        "response": gr.Textbox(label="Response"),
    },
)
```

**Inputs:** The expected inputs depend on the model's task type. For text generation models, use `prompt`. For other tasks, check the model's documentation on the Hub.

**Outputs:** Like other nodes, output names are arbitrary and map to return values in order.

### Testing Nodes

You can test-run any node in isolation using the `.test()` method:

```python
tts = GradioNode("mrfakename/MeloTTS", api_name="/synthesize", ...)
result = tts.test(text="Hello world", speaker="EN-US")
# Returns: {"audio": "/path/to/audio.wav"}
```

If called without arguments, `.test()` auto-generates example values using each input component's `.example_value()` method:

```python
result = tts.test()  # Uses gr.Textbox().example_value(), etc.
```

This is useful for quickly checking what format a node returns without wiring up a full workflow.

### Input Types

Each node's `inputs` dict accepts four types of values:

| Type | Example | Result |
|------|---------|--------|
| **Gradio component** | `gr.Textbox(label="Topic")` | Creates UI input |
| **Port reference** | `other_node.output_name` | Connects nodes |
| **Fixed value** | `"Auto"` or `42` | Constant, no UI |
| **Callable** | `random.random` | Called each run, no UI |

### Output Types

Each node's `outputs` dict accepts two types of values:

| Type | Example | Result |
|------|---------|--------|
| **Gradio component** | `gr.Image(label="Result")` | Displays output in node card |
| **None** | `None` | Hidden, but can connect to downstream nodes |

### Scatter / Gather

When a node outputs a list and you want to process each item individually, use `.each` to scatter and `.all()` to gather:

```python
script = FnNode(fn=generate_script, inputs={...}, outputs={"lines": gr.JSON()})

tts = FnNode(
    fn=text_to_speech,
    inputs={
        "text": script.lines.each["text"],      # Scatter: run once per item
        "speaker": script.lines.each["speaker"],
    },
    outputs={"audio": gr.Audio()},
)

final = FnNode(
    fn=combine_audio,
    inputs={"audio_files": tts.audio.all()},    # Gather: collect all outputs
    outputs={"audio": gr.Audio()},
)
```

### Choice Nodes

Sometimes you want to offer multiple alternatives for the same step in your workflow—for example, two different TTS providers or image generators. Use the `|` operator to create a **choice node** that lets users switch between variants in the UI:

```python
host_voice = GradioNode(
    space_or_url="abidlabs/tts",
    api_name="/generate_voice_design",
    inputs={
        "voice_description": gr.Textbox(label="Host Voice"),
        "language": "Auto",
        "text": "Hi! I'm the host!",
    },
    outputs={"audio": gr.Audio(label="Host Voice")},
) | GradioNode(
    space_or_url="mrfakename/E2-F5-TTS",
    api_name="/basic_tts",
    inputs={
        "ref_audio_input": gr.Audio(label="Reference Audio"),
        "gen_text_input": gr.Textbox(label="Text to Generate"),
    },
    outputs={"audio": gr.Audio(label="Host Voice")},
)

# Downstream nodes connect to host_voice.audio regardless of which variant is selected
dialogue = FnNode(
    fn=generate_dialogue,
    inputs={"host_voice": host_voice.audio, ...},
    ...
)
```

In the canvas, choice nodes display an accordion UI where you can:
- See all available variants
- Click to select which variant to use
- View the selected variant's input components

The selected variant is persisted per sheet, so your choice is remembered across page refreshes. All variants must have the same output ports (so downstream connections work regardless of selection), but they can have different input ports.

## Putting It Together: A Mock Podcast Generator

```python
import gradio as gr
from daggr import FnNode, GradioNode, Graph

# Generate voice profiles
host_voice = GradioNode(
    space_or_url="abidlabs/tts",
    api_name="/generate_voice_design",
    inputs={
        "voice_description": gr.Textbox(label="Host Voice", value="Deep British voice..."),
        "language": "Auto",
        "text": "Hi! I'm the host.",
    },
    outputs={"audio": gr.Audio(label="Host Voice")},
)

guest_voice = GradioNode(
    space_or_url="abidlabs/tts",
    api_name="/generate_voice_design",
    inputs={
        "voice_description": gr.Textbox(label="Guest Voice", value="Friendly American voice..."),
        "language": "Auto",
        "text": "Hi! I'm the guest.",
    },
    outputs={"audio": gr.Audio(label="Guest Voice")},
)

# Generate dialogue (would be an LLM call in production)
def generate_dialogue(topic: str, host_voice: str, guest_voice: str) -> tuple[list, str]:
    dialogue = [
        {"voice": host_voice, "text": "Hello, how are you?"},
        {"voice": guest_voice, "text": "I'm great, thanks!"},
    ]
    html = "<b>Host:</b> Hello!<br><b>Guest:</b> I'm great!"
    return dialogue, html  # Returns tuple: first value -> "json", second -> "html"

dialogue = FnNode(
    fn=generate_dialogue,
    inputs={
        "topic": gr.Textbox(label="Topic", value="AI"),
        "host_voice": host_voice.audio,
        "guest_voice": guest_voice.audio,
    },
    outputs={
        "json": gr.JSON(visible=False),  # Maps to first return value
        "html": gr.HTML(label="Script"),  # Maps to second return value
    },
)

# Generate audio for each line (scatter)
def text_to_speech(text: str, audio: str) -> str:
    return audio  # Would call TTS model in production

samples = FnNode(
    fn=text_to_speech,
    inputs={
        "text": dialogue.json.each["text"],
        "audio": dialogue.json.each["voice"],
    },
    outputs={"audio": gr.Audio(label="Sample")},
)

# Combine all audio (gather)
def combine_audio(audio_files: list[str]) -> str:
    from pydub import AudioSegment
    combined = AudioSegment.empty()
    for path in audio_files:
        combined += AudioSegment.from_file(path)
    combined.export("output.mp3", format="mp3")
    return "output.mp3"

final = FnNode(
    fn=combine_audio,
    inputs={"audio_files": samples.audio.all()},
    outputs={"audio": gr.Audio(label="Full Podcast")},
)

graph = Graph(name="Podcast Generator", nodes=[host_voice, guest_voice, dialogue, samples, final])
graph.launch()
```

## Sharing and Hosting

Create a public URL to share your workflow with others:

```python
graph.launch(share=True)
```

This generates a temporary public URL (expires in 1 week) using Gradio's tunneling infrastructure.

For permanent hosting, you can deploy Daggr apps on [Hugging Face Spaces](https://huggingface.co/spaces) using the Gradio SDK. Just create a new Space with the Gradio SDK, add your workflow code to `app.py`, and include `daggr` in your `requirements.txt`.

Daggr automatically reads the `GRADIO_SERVER_NAME` and `GRADIO_SERVER_PORT` environment variables, which Hugging Face Spaces sets automatically for Gradio apps. This means your daggr app will work on Spaces without any additional configuration.

## Persistence and Sheets

Daggr automatically saves your workflow state—input values, node results, and canvas position—so you can pick up where you left off after a page reload.

### Sheets

**Sheets** are like separate workspaces within a single Daggr app. Each sheet has its own:
- Input values for all nodes
- Cached results from previous runs  
- Canvas zoom and pan position

Use sheets to work on multiple projects within the same workflow. For example, in a podcast generator app, each sheet could represent a different podcast episode you're working on.

The sheet selector appears in the title bar. Click to switch between sheets, create new ones, rename them (double-click), or delete them.

### How Persistence Works

| Environment | User Status | Persistence |
|-------------|-------------|-------------|
| **Local** | Not logged in | ✅ Saved as "local" user |
| **Local** | HF logged in | ✅ Saved under your HF username |

When running locally, your data is stored in a SQLite database (`.daggr_sessions.db`) in the current directory.

### The `persist_key` Parameter

By default, the `persist_key` is derived from your graph's `name`:

```python
Graph(name="My Podcast Generator")  # persist_key = "my_podcast_generator"
```

If you later rename your app but want to keep the existing saved data, set `persist_key` explicitly:

```python
Graph(name="Podcast Generator v2", persist_key="my_podcast_generator")
```

### Disabling Persistence

For scratch workflows or demos where you don't want data saved:

```python
Graph(name="Quick Demo", persist_key=False)
```

This disables all persistence—no sheets UI, no saved state.

## Hugging Face Authentication

Daggr automatically uses your local Hugging Face token for both `GradioNode` and `InferenceNode`. This enables:

- **ZeroGPU quota tracking**: Your HF token is sent to Gradio Spaces running on ZeroGPU, so your usage is tracked against your account's quota
- **Private Spaces access**: Connect to private Gradio Spaces you have access to
- **Gated models**: Use gated models on Hugging Face that require accepting terms of service

To log in with your Hugging Face account:

```bash
pip install huggingface_hub
hf auth login
```

You'll be prompted to enter your token, which you can find at https://huggingface.co/settings/tokens. 

Once logged in, the token is saved locally and daggr will automatically use it for all `GradioNode` and `InferenceNode` calls—no additional configuration needed.

Alternatively, you can set the `HF_TOKEN` environment variable directly:

```bash
export HF_TOKEN=hf_xxxxx
```

## LLM-Friendly Error Messages

Daggr is designed to be LLM-friendly, making it easy for AI coding assistants to generate and debug workflows. When you (or an LLM) make a mistake, Daggr provides detailed, actionable error messages with suggestions:

**Invalid API endpoint:**
```
ValueError: API endpoint '/infer' not found in 'hf-applications/background-removal'. 
Available endpoints: ['/image', '/text', '/png']. Did you mean '/image'?
```

**Typo in parameter name:**
```
ValueError: Invalid parameter(s) {'promt'} for endpoint '/generate_image' in 
'hf-applications/Z-Image-Turbo'. Did you mean: 'promt' -> 'prompt'? 
Valid parameters: {'width', 'height', 'seed', 'prompt'}
```

**Missing required parameter:**
```
ValueError: Missing required parameter(s) {'prompt'} for endpoint '/generate_image' 
in 'hf-applications/Z-Image-Turbo'. These parameters have no default values.
```

**Invalid output port reference:**
```
ValueError: Output port 'img' not found on node 'Z-Image-Turbo'. 
Available outputs: image. Did you mean 'image'?
```

**Invalid function parameter:**
```
ValueError: Invalid input(s) {'toppic'} for function 'generate_dialogue'. 
Did you mean: 'toppic' -> 'topic'? Valid parameters: {'topic', 'host_voice', 'guest_voice'}
```

**Invalid model name:**
```
ValueError: Model 'meta-llama/nonexistent-model' not found on Hugging Face Hub. 
Please check the model name is correct (format: 'username/model-name').
```

These errors make it easy for LLMs to understand what went wrong and fix the generated code automatically, enabling a smoother AI-assisted development experience.

### Discovering Output Formats

When building workflows, LLMs can use `.test()` to discover a node's actual output format:

```python
# LLM wants to understand what whisper returns
whisper = InferenceNode("openai/whisper-large-v3", inputs={"audio": gr.Audio()})
result = whisper.test(audio="sample.wav")
# Returns: {"text": "Hello, how are you?"}
```

This helps LLMs:
- Understand the structure of node outputs
- Apply `postprocess` functions to extract specific values
- Create intermediate `FnNode`s to transform data between nodes

For example, if a node returns multiple values but you only need one:

```python
# After discovering the output format with .test()
bg_remover = GradioNode(
    "hf-applications/background-removal",
    api_name="/image",
    inputs={"image": some_image.output},
    postprocess=lambda original, final: final,  # Keep only the second output
    outputs={"image": gr.Image()},
)
```

## Running Locally

While in our examples above, we've seen how Daggr works with remote Gradio Spaces and Hugging Face Inference Providers, it's also well-suited for completely local, offline workflows.

### Automatic Local Execution

The easiest way to run a Space locally is to set `run_locally=True` on any `GradioNode`. Daggr will automatically clone the Space, install dependencies in an isolated virtual environment, and launch the Gradio app:

```python
from daggr import GradioNode, Graph
import gradio as gr

# Automatically clone and run the Space locally
background_remover = GradioNode(
    "hf-applications/background-removal",
    api_name="/image",
    run_locally=True,  # Run locally instead of calling the remote API
    inputs={"image": gr.Image(label="Input Image")},
    outputs={"final_image": gr.Image(label="Output")},
)

graph = Graph(name="Local Background Removal", nodes=[background_remover])
graph.launch()
```

On first run, daggr will:

1. Clone the Space repository to `~/.cache/huggingface/daggr/spaces/`
2. Create an isolated virtual environment with the Space's dependencies
3. Launch the Gradio app on an available port
4. Connect to it automatically

Subsequent runs reuse the cached clone and venv, making startup much faster.

### Graceful Fallback

If local execution fails (missing dependencies, GPU requirements, etc.), daggr automatically falls back to the remote API and prints helpful guidance:

```
⚠️  Local execution failed for 'owner/space-name'
Reason: Failed to install dependencies
Logs: ~/.cache/huggingface/daggr/logs/owner_space-name_pip_install_2026-01-27.log
Falling back to remote API...
```

To disable fallback and see the full error (useful for debugging):

```bash
export DAGGR_LOCAL_NO_FALLBACK=1
```

### Environment Variables

| Variable | Default | Description |
|----------|---------|-------------|
| `DAGGR_LOCAL_TIMEOUT` | `120` | Seconds to wait for the app to start |
| `DAGGR_LOCAL_VERBOSE` | `0` | Set to `1` to show app stdout/stderr |
| `DAGGR_LOCAL_NO_FALLBACK` | `0` | Set to `1` to disable fallback to remote |
| `DAGGR_UPDATE_SPACES` | `0` | Set to `1` to re-clone cached Spaces |
| `GRADIO_SERVER_NAME` | `127.0.0.1` | Host to bind to. Set to `0.0.0.0` on HF Spaces |
| `GRADIO_SERVER_PORT` | `7860` | Port to bind to |

### Manual Local URL

You can also run a Gradio app yourself and point to it directly:

```python
from daggr import GradioNode, Graph
import gradio as gr

# Connect to a Gradio app you're running locally
local_model = GradioNode(
    "http://localhost:7860",  # Local URL instead of Space ID
    api_name="/predict",
    inputs={"text": gr.Textbox(label="Input")},
    outputs={"result": gr.Textbox(label="Output")},
)

graph = Graph(name="Local Workflow", nodes=[local_model])
graph.launch()
```

This approach lets you run your entire workflow offline, use custom or fine-tuned models, and avoid API rate limits.

## Hot Reload Mode

During development, you can use the `daggr` CLI to run your app with automatic hot reloading. When you make changes to your Python file or its dependencies, the app automatically restarts:

```bash
daggr examples/01_quickstart.py
```

This is much faster than manually stopping and restarting your app each time you make a change.

### CLI Options

```bash
daggr <script> [options]
```

| Option | Description |
|--------|-------------|
| `--host` | Host to bind to (default: `127.0.0.1`) |
| `--port` | Port to bind to (default: `7860`) |
| `--no-reload` | Disable auto-reload |
| `--no-watch-daggr` | Don't watch daggr source for changes |

### What Gets Watched

By default, the CLI watches for changes in:

- **Your script file** and its directory
- **Local imports** from your script
- **The daggr source code** itself (useful when developing daggr)

To disable watching the daggr source (e.g., in production-like testing):

```bash
daggr examples/01_quickstart.py --no-watch-daggr
```

### API Caching

To speed up reloads, daggr caches Gradio Space API info in `~/.cache/huggingface/daggr/`. This means:

- **First run**: Connects to each Gradio Space to fetch API info (cached to disk)
- **Subsequent reloads**: Loads from cache, no network calls needed

If you change a Space's API or encounter stale cache issues, clear the cache:

```bash
rm -rf ~/.cache/huggingface/daggr
```

### When to Use Hot Reload

Use `daggr <script>` when you're actively developing and want instant feedback on changes.

Use `python <script>` when you want the standard behavior (no file watching, direct execution).

## Beta Status

> [!WARNING]
> Daggr is in active development. APIs may change between versions, and while we persist workflow state locally, data loss is possible during updates. We recommend not relying on daggr for production-critical workflows yet. Please [report issues](https://github.com/gradio-app/daggr/issues) if you encounter bugs!

## Development

```bash
pip install -e ".[dev]"
ruff check --fix --select I && ruff format
```
