About NextChat

NextChat is a lightweight AI chat assistant that works with several model providers, including Claude, GPT, Gemini and DeepSeek, and local runtimes such as Ollama. It is available as a web app and PWA, with desktop apps for Windows, macOS and Linux built using Tauri, and mobile apps. The code is written in TypeScript with Next.js and React, and it is released under the MIT license.

You can deploy your own instance, for example on Vercel, or use the hosted NextChatAI service, which the project describes as pay-as-you-go and not requiring your own API key. The README also notes support for the Model Context Protocol when an environment flag is set before building. An Enterprise Edition targets companies that need private deployment, brand customization, centralized management of AI resources, permission controls and integration of internal knowledge bases.
