## Deploy

Offpage supports deploying generated websites to three platforms:

| Provider | How it works |
|:---------|:-------------|
| **Netlify** | Creates a site via API, deploys a zip with `index.html`. Reuses existing site on subsequent deploys. |
| **Vercel** | Posts base64-encoded HTML to the deployments API. |
| **GitHub Pages** | Creates a repo, uploads `index.html`, enables GitHub Pages. |
| **Local export** | Saves the HTML file to any location on your disk via system save dialog. |

API tokens are stored locally in SQLite &mdash; never sent anywhere except the provider's API. Tokens can be managed in **Settings**.

<br>

## AI Model

The app runs AI inference locally using [llama.cpp](https://github.com/ggerganov/llama.cpp) as a sidecar process.

| Model | Size | For |
|:------|:-----|:----|
| **Qwen2.5-Coder-7B-Instruct** (Q4_0) | ~4.3 GB | 16 GB+ RAM &mdash; recommended |
| **Qwen2.5-Coder-3B-Instruct** (Q4_0) | ~2.0 GB | 8 GB RAM &mdash; minimum |

Models are downloaded from Hugging Face on first launch and stored in your app data directory. The app auto-detects previously downloaded models on subsequent launches.
