NextChat
NextChat (formerly ChatGPT-Next-Web) is the lightweight champion of ChatGPT-style UIs. It deploys in minutes, runs almost anywhere, and focuses on core chat functionality without bloat.
What it is
NextChat is a single-page React application that connects to any OpenAI-compatible API endpoint. It's designed to be deployed instantly - one click to Vercel, one Docker command, or a static build served from any web server. No database, no backend, no configuration beyond setting your API endpoint.
Why this matters
NextChat's simplicity is its superpower. It strips away everything unnecessary:
- Instant deploy: Vercel, Docker, or static - choose your path in minutes
- Zero infrastructure: no database, no user system, no queues
- Mask system: create, save, and share character personas
- Auto-compress: long conversations automatically summarize to fit context windows
