Purl is a self-hosted, open-source AI design generator. Type a prompt, get a full HTML/CSS/JS page streamed live into a sandboxed preview, then iterate by chat or click an element to edit it directly. Every change is a restorable version. Bring your own model (OpenAI, Anthropic, OpenRouter, Groq, DeepSeek, Gemini, Ollama) or run fully offline in mock mode — no API key needed. No telemetry. MIT licensed, commercial use included.
