Next Chat is an open-source project on GitHub, and an official deployment is available here.
For certain use cases, we have self-hosted the free open-source version of Next Chat, which can be accessed here. And obliviously everyone can use it, but through different ways.
Since the open-source version offers limited role-based access control, we do not give the access code to everyone—only to authorized users. If you have the access code, several flagship models from OpenAI, Anthropic, Google, DeepSeek, and Alibaba are already supported using the site owner’s API key.
If you are not using an access code, you will have to set it up on your own. Don’t worry, it’s going to be easy.
