🎉 What's New 2025/2/25

Parameter Extractor Node: Added parameter extraction node that can automatically extract structured information from text and output in JSON format!

🎉 What's New 2025/1/21

Subgraph Node Support: Added subgraph node that allows you to encapsulate and reuse complete sub-workflows!

📦 Modular: Encapsulate complex workflows as standalone subgraph nodes

🔄 Reusable: Reuse the same subgraph node across different workflows

🎯 Maintainable: Update and maintain sub-workflow logic independently

🎉 What's New 2025/1/8

Human Node: Added a new human-in-the-loop node supporting key scenarios:

🛠️ Tool Call Review: Human review, edit, or approve tool calls requested by the LLM

🎉 What's New 2024/12/18

If-Else Node: Added If-Else node to support conditional logic in workflows! The node supports various condition types including Contains, Not contains, Start with, End with, Is, Is not, Is empty, and Is not empty. Multiple conditions can be combined using AND/OR operators for complex conditional logic, allowing you to create sophisticated branching workflows based on your data.

🎉 What's New 2024/12/7

Code Execution Node: Added Python code execution capabilities to workflows! This node allows you to write and execute Python scripts directly within your workflow, supporting variable references and dynamic data transformations. Perfect for arithmetic operations, data processing, text manipulation, and custom logic that goes beyond preset node functionalities.

🎉 What's New 2024/11/12

Intent Recognition Node: New Intent Recognition node that can automatically identify user input intent based on preset categories, supporting multi-classification routing! <img src="assets/intent.png" alt="intent recognition" width="500" />

CrewAI Node Support: Now you can leverage CrewAI's powerful multi-agent capabilities in your workflows! Create sophisticated agent teams and orchestrate complex collaborative tasks with ease. <img src="assets/crewai.jpg" alt="crewai" width="500" />

Flock is a workflow-based low-code platform for rapidly building chatbots, RAG applications, and coordinating multi-agent teams. Built on LangChain and LangGraph, it provides a flexible, low-code orchestrating solution for collaborative agents, supporting chatbots, RAG applications, agents, and multi-agent systems, with the capability for offline operation.

🤖️ Overview

Work Flow

Node Types and Functions

Flock's workflow system consists of various node types, each serving a specific purpose:

Input Node: Processes initial input and converts it into a format the workflow can handle.
LLM Node: Utilizes large language models for text generation and processing.
Retrieval Node: Fetches relevant information from knowledge bases.
Tool Node: Executes specific tasks or operations, extending workflow functionality.
Retrieval Tool Node: Combines retrieval capabilities with tool functionality.
Intent Recognition Node: Automatically identifies user input intent based on preset categories and routes to different processing flows.
Answer Node: Generates final answers or outputs, integrating results from previous nodes.
Subgraph Node: Encapsulates a complete sub-workflow, allowing for modular design.
Start and End Nodes: Mark the beginning and end of the workflow.

Future planned nodes include:

File Upload Node
Parameter Extraction Node

These nodes can be combined to create powerful and flexible workflows suitable for various complex business needs and application scenarios.

Image Tools use

Knowledge Retrieval

Human in the loop (human approval or let the LLM rethink or ask human for help)

Inspired by the StreetLamb project and its tribe project , Flock adopts much of the approach and code. Building on this foundation, it introduces some new features and directions of its own.

Some of the layout in this project references Lobe-chat, Dify, and fastgpt. They are all excellent open-source projects, thanks🙇‍.

👨‍💻 Development
