What It Is

NextChat is an open-source AI chat platform built around the idea of “Your Keys Your Rules”: users bring their own API keys, while the platform serves as a unified chat interface for services such as ChatGPT, Claude, Gemini, DeepSeek, and Midjourney. It emphasizes transparency, openness, and full user control, with a focus on pay-as-you-go usage rather than subscription plans.

Core Features and Use Cases

Based on the available description, NextChat’s main value lies in multi-model aggregation and user-managed keys. Users can access different models from a single platform, making it suitable for everyday AI conversations, content generation, coding assistance, creative exploration, and image generation via services such as Midjourney. Output quality is not determined by NextChat itself, but primarily by the connected model provider and the specific model version used.

Pricing and Costs

Its pricing is described as Pay As You Go, with no subscriptions and no hidden fees. Since it uses a bring-your-own-API-key model, actual costs are typically determined by the API or usage fees charged by third-party services such as OpenAI, Anthropic, Google, DeepSeek, and Midjourney. The source text does not state whether NextChat itself charges hosting fees, service fees, or fees for premium features, so budget planning should still be verified against the actual product page.

Pros and Cons

The advantages are that it is open-source and transparent, helps avoid platform lock-in, supports multiple mainstream models, and is friendlier to light users thanks to usage-based billing. For developers and small teams that care about control, bringing your own key also makes cost allocation and permission management easier. The limitations are that the available information is limited: it does not explain how API keys are encrypted and stored, whether chat history is stored locally, whether team collaboration, workflows, plugins, web search/retrieval, or other advanced features are supported, or whether there is a Chinese interface and customer support.

Who It’s For and Access from China

NextChat is better suited to individual users, developers, and small teams who understand API keys and want a unified entry point for managing multiple models. It is less suitable for users who are completely unfamiliar with API configuration and want an out-of-the-box product with full customer support. Access from mainland China is not disclosed in the source text. In addition, the availability of supported services such as ChatGPT, Claude, Gemini, and Midjourney may vary in mainland China in terms of network access and payment options. Alternatives include Open WebUI, LibreChat, LobeChat, as well as using ChatGPT, Claude, Gemini, or DeepSeek directly.
