Habitat

什麼是 Habitat？

Everyone wants to build an AI app — then they hit "how do I stream the response" and stall. Habitat's AI App Starter hands you the boring part, working: real token-by-token streaming, a clean chat UI, and bring-your-own-model (any OpenAI-compatible API — OpenAI, Groq, OpenRouter, Ollama). Runs out of the box in mock mode, no key needed. Next.js 15 + Tailwind v4, typed and easy to extend into auth/billing/RAG. From idea to a running AI app in an evening.
