Pipecat Flows is an add-on framework for Pipecat that allows you to build structured conversations in your AI applications. It enables you to create both predefined conversation paths and dynamically generated flows while handling the complexities of state management and LLM interactions.

The framework consists of:

• A Python module for building conversation flows with Pipecat
• A visual editor for designing and exporting flow configurations

Dependencies

• Python 3.10 or higher
• Pipecat

Installation

1. Install uv

   curl -LsSf https://astral.sh/uv/install.sh | sh

   Need help? Refer to the uv install documentation.

2. Install the module

   # For new projects
   uv init my-pipecat-flows-app
   cd my-pipecat-flows-app
   uv add pipecat-ai-flows
   
   # Or for existing projects
   uv add pipecat-ai-flows

Using pip? You can still use pip install pipecat-ai-flows to get set up.

Quick Start

See Quick Start README.

For more detailed examples and guides, visit our documentation.

Examples

The repository includes several complete example implementations demonstrating various features of Pipecat Flows.

Available Examples

• Static Flows: Pre-defined conversation paths including food ordering, movie exploration, patient intake, and travel planning
• Dynamic Flows: Runtime-generated flows including insurance quotes, restaurant reservations, and warm transfers

Each example is available in multiple LLM provider formats (OpenAI, Anthropic, Google Gemini, AWS Bedrock) to demonstrate cross-platform compatibility.

Getting Started with Examples

For detailed setup instructions, configuration, and running examples, see the Examples README.

Quick start:

# Install dependencies
uv sync
uv pip install "pipecat-ai[daily,openai,deepgram,cartesia,silero,examples]"

# Configure environment
cp env.example .env  # Add your API keys

# Run an example
uv run python examples/static/food_ordering.py -u YOUR_DAILY_ROOM_URL

Contributing to the framework

1. Clone the repository and navigate to it:

   git clone https://github.com/pipecat-ai/pipecat-flows.git
   cd pipecat-flows

2. Install development dependencies:

   uv sync --group dev

3. Install the git pre-commit hooks (these help ensure your code follows project rules):

   uv run pre-commit install

   The package is automatically installed in editable mode when you run uv sync.

Tests

The package includes a comprehensive test suite covering the core functionality.

Setup Test Environment

1. Install Dependencies:

   uv sync --group dev
   uv add "pipecat-ai[google,aws,openai,anthropic]"

Running Tests

Run all tests:

uv run pytest tests/

Run specific test file:

uv run pytest tests/test_state.py

Run specific test:

uv run pytest tests/test_state.py -k test_initialization

Run with coverage report:

uv run pytest tests/ --cov=pipecat_flows

Pipecat Flows Editor

A visual editor for creating and managing Pipecat conversation flows.

Features

• Visual flow creation and editing
• Import/export of flow configurations
• Support for node and edge functions
• Merge node support for complex flows
• Real-time validation

Naming Conventions

While the underlying system is flexible with node naming, the editor follows these conventions for clarity:

• Start Node: Named after your initial conversation state (e.g., "greeting", "welcome")
• End Node: Conventionally named "end" for clarity, though other names are supported
• Flow Nodes: Named to reflect their purpose in the conversation (e.g., "get_time", "confirm_order")

These conventions help maintain readable and maintainable flows while preserving technical flexibility.

Online Editor

The editor is available online at flows.pipecat.ai.

Local Development

Prerequisites

• Node.js (v14 or higher)
• npm (v6 or higher)

Installation

Clone the repository

git clone [email protected]:pipecat-ai/pipecat-flows.git

Navigate to project directory

cd pipecat-flows/editor

Install dependencies

npm install

Start development server

npm run dev

Open the page in your browser: http://localhost:5173.

Usage

1. Create a new flow using the toolbar buttons
2. Add nodes by right-clicking in the canvas
   • Start nodes can have descriptive names (e.g., "greeting")
   • End nodes are conventionally named "end"
3. Connect nodes by dragging from outputs to inputs
4. Edit node properties in the side panel
5. Export your flow configuration using the toolbar

Examples

The editor/examples/ directory contains sample flow configurations:

• food_ordering.json
• movie_explorer.py
• patient_intake.json
• restaurant_reservation.json
• travel_planner.json

To use an example:

1. Open the editor
2. Click "Import Flow"
3. Select an example JSON file

See the examples directory for the complete files and documentation.
