📸 Snapshot

`1` Function Calling Plugin System

By building a powerful plugin ecosystem, ChatGPT not only can provide real-time news updates, but it can also assist you in easily querying documents and accessing various e-commerce data. This allows ChatGPT to play a key role in a wider range of fields. If you are interested in writing plugins, we provide detailed component development documentation, SDKs, and template files in the 🧩 Plugin System section below. Let's work together to make ChatGPT more powerful and easier to use.

`2` Prompt Agent Market

In our agent market, we have accumulated a large number of practical prompt agents that have been used in daily work and study. You can also share your agents here and iterate and optimize your prompt agents with more people. You can submit your agents through 🤖/🏪 Submit Agents, and our automated i18n workflow will automatically translate your agents into multiple languages, allowing users around the world to enjoy your wisdom.

`3` Progress Web App

Utilize the Progressive Web Application (PWA) technology to achieve a seamless LobeChat experience on your computer or mobile device.

Note
If you are unfamiliar with the installation process of PWA, you can add LobeChat as your desktop application (also applicable to mobile devices) by following these steps:

Launch the Chrome or Edge browser on your computer

Visit the LobeChat webpage

In the upper right corner of the address bar, click on the Install icon

Follow the instructions on the screen to complete the PWA installation

`4` Theme Mode Selection

LobeChat offers two unique theme modes - Light Mode and Dark Mode, as well as rich color customization options to meet your personalized needs. By default, our themes will intelligently switch based on your system settings, but if you prefer manual control, you can easily switch in the settings.

`5` Mobile Device Adaptation

We have carried out a series of optimization designs for mobile devices to enhance the user's mobile experience. Currently, we are iterating on the mobile user experience to achieve smoother and more intuitive interactions. If you have any suggestions or ideas, we welcome you to provide feedback through GitHub Issues or Pull Requests.

🛳 Self Hosting

LobeChat provides a self-hosted version with Vercel. This allows you to build your own chatbot within a few minutes, without any prior knowledge. If you want to deploy this service yourself, you can follow these steps:

Prepare your OpenAI API Key.
Click the button below to start deployment: Deploy with Vercel. Log in directly with your GitHub account and remember to fill in the API Key and access code CODE on the environment variable page;
After deployment, you can start using it;
Bind a custom domain (optional): The DNS of the domain assigned by Vercel is polluted in some areas, binding a custom domain can connect directly.

Note
This project provides some additional configuration items, set with environment variables, The complete list of environment variables can be found in the 📘 Environment Variables :

Environment Variable	Required	Description	Example
`OPENAI_API_KEY`	Yes	This is the API key you apply on the OpenAI account page	`sk-xxxxxx...xxxxxx`
`OPENAI_PROXY_URL`	No	If you manually configure the OpenAI interface proxy, you can use this configuration item to override the default OpenAI API request base URL	`https://api.chatanywhere.cn/v1` The default value is `https://api.openai.com/v1`
`ACCESS_CODE`	No	Add a password to access this service, the password should be a 6-digit number or letter	`awCT74` or `e3@09!`

Keep Updated

If you have deployed your own project following the one-click deployment steps in the README, you might encounter constant prompts indicating "updates available". This is because Vercel defaults to creating a new project instead of forking this one, resulting in an inability to accurately detect updates. We suggest you redeploy using the following steps, 📘 Maintaining Updates with LobeChat Self-Deployment.
