How to Set Up and Use NextChat on Nife-Deploy OpenHub: Deploying a Self-Hosted AI Chat Interface

How to Set Up and Use NextChat on Nife-Deploy OpenHub: Deploying a Self-Hosted AI Chat Interface​

NextChat (ChatGPT Next Web) is a lightweight and modern AI chat interface that allows users to interact with large language models such as OpenAI, Azure OpenAI, Gemini, and other compatible APIs through a clean web interface.

The platform provides a fast and responsive UI for chatting with AI models while allowing developers and organizations to host the application themselves. Self-hosting ensures that API keys, conversations, and configurations remain fully under the user’s control.

NextChat supports features such as conversation management, multi-model support, system prompts, and secure API key configuration through environment variables. These capabilities make it an ideal solution for developers, AI enthusiasts, and teams who want a customizable AI chat environment.

Deploying NextChat through Nife-Deploy OpenHub allows users to launch the application quickly using a managed container environment without needing to manually configure servers or infrastructure.



1. Accessing the Nife-Deploy OpenHub Catalog​

Access the Nife-Deploy Console​

Visit: Visit the Nife launchpad:
https://launch.nife.io

Log in: Log in using your registered Nife account credentials to access the platform dashboard. If you are new to the platform, create an account to continue.

Navigation: Once logged in, locate the sidebar on the left-hand side of the dashboard. Under the Automation section, click on Templates.

Selection: Open the Marketplace, which lists available open-source applications that can be deployed instantly.

Search for NextChat​

2. Configuring and Initiating Deployment​

Start Deployment​

Action: Hover over the NextChat application tile and click the Quick Deploy button. This opens the deployment configuration popup.

Review Deployment Settings​

Before launching the application, review the configuration options in the deployment popup.

Application Name:​

Assign a unique name for your NextChat instance. The platform may automatically generate a name for the deployment, but you can modify it to better identify your application.

Environment Variables:​

NextChat requires an API key to connect with AI providers.

Add the OpenAI API key using the following variable:

OPENAI_API_KEY=<YOUR_OPENAI_API_KEY>

This key allows the application to communicate with the OpenAI API and generate AI responses.

### Cloud Region:

Choose the deployment region closest to your location to reduce latency and improve performance when accessing the chat interface.

### Resource Allocation:

The platform automatically assigns suitable CPU and memory resources for the container. These default resources are generally sufficient because NextChat is a lightweight web-based interface.

### Finalization:

After reviewing the configuration settings, click **Deploy Application** to start the deployment process. The Nife-Deploy OpenHub platform will automatically pull the container image, configure networking, and launch the NextChat instance.
