4. Feature Overview

Nexfly is a microservice-based open-source project built on the Spring AI framework, featuring RAG and AI orchestration. It simplifies the development of AI-powered applications, avoids unnecessary complexity, and makes it easier for enterprises to adopt AI capabilities.

Seamless Integration

• Quickly connect to third-party business systems to add AI capabilities to existing systems.
• By integrating Spring Security, it quickly connects third-party account systems that follow the OAuth2 standard, such as WeChat and Google.

Deep Document Parsing

• Through deep integration of Spring AI, Tesseract OCR, and other frameworks, it performs OCR visual recognition and parsing of documents to achieve precise document splitting.
• Supports processing of multiple unstructured data formats, including PDF, DOC, and PPT

Flexible RAG Pipeline Configuration

• The fully optimized RAG workflow supports the diverse ecosystems of very large enterprises.
• Both the LLM and the embedding model are configurable.

5. Tech Stack

 Quick Start

 Prerequisites

• CPU >= 4 cores
• RAM >= 16 GB
• Docker >= 24.0.0 & Docker Compose >= v2.26.1
• If Docker is not installed on your machine (Windows, Mac, or Linux), see the Install Docker Engine documentation to install it.

 Start the Server

1. Clone the repository:

$ git clone nexfly

2. Enter  docker  folder and start the server with the prebuilt Docker image:

$ cd nexfly/docker
$ docker compose up -d

To download and run a specific version of the Docker image, find the NEXFLY_VERSION variable in the docker/.env file and set it to that version.

The first build pulls the Nexfly image and middleware images and may take a while; please be patient.

3. After the server starts, check its status again:

$ docker logs -f nexfly-system
$ docker logs -f nexfly-auth
$ docker logs -f nexfly-gateway

The server is up when you see the following screen:

Connected to the target VM, address: '127.0.0.1:65520', transport: 'socket'
  _ _                 ______   _

                                    |___/

4. Enter your server's IP address in the browser and sign in to Nexfly.

In the example above, simply enter http://127.0.0.1: if you have not changed the configuration, no port is needed (the default HTTP port is 80).
