+Deploy Moltbot on Render using Infrastructure as Code. The included `render.yaml` Blueprint defines your entire stack declaratively—service, disk, environment variables—so you can deploy with a single click and version your infrastructure alongside your code.
## Prerequisites
- A [Render account](https://render.com) (free tier available)
- An API key from your preferred [model provider](/providers)
+## Alternative: Wrapper with Installer
+
+For a deployment with a built-in installer and proxied Control UI (including WebSocket support), see community wrappers (e.g. in the ecosystem docs). Such wrappers may provide:
+
+- **Install Wizard** at `/install` (password protected)
+- **Control UI** reverse-proxied with WebSocket support
+- **Export / Import backups** to migrate deployments

+#### Configuring LLM API Keys
+
+After deployment, you need to configure at least one LLM provider API key. Set these in the Render dashboard:
+
+**Most common providers:**
+
+- **Anthropic (Claude)**: `ANTHROPIC_API_KEY` — Get from [Anthropic Console](https://console.anthropic.com/)
+- **OpenAI (GPT)**: `OPENAI_API_KEY` — Get from [OpenAI Platform](https://platform.openai.com/api-keys)
+- **Google Gemini**: `GEMINI_API_KEY` — Get from [Google AI Studio](https://aistudio.google.com/app/apikey)
+- **Groq**: `GROQ_API_KEY` — Get from [Groq Console](https://console.groq.com/keys)
+- **OpenRouter**: `OPENROUTER_API_KEY` — Get from [OpenRouter](https://openrouter.ai/keys)
+
+**Additional providers:**
+
+- `MISTRAL_API_KEY` — Mistral AI
+- `XAI_API_KEY` — xAI (Grok)
+- `OPENCODE_API_KEY` — OpenCode Zen
+- `DEEPGRAM_API_KEY` — Deepgram (speech-to-text)
+
+To set API keys:
+
+1. Go to **Dashboard → your service → Environment**
+2. Click **Add Environment Variable**
+3. Enter the variable name (e.g., `ANTHROPIC_API_KEY`)
+4. Enter your API key value
+5. Click **Save Changes**
+
+The service will automatically redeploy with the new environment variable.
+
+**Alternative: Config file method**
+
+You can also configure API keys in the `moltbot.json` config file (under `MOLTBOT_STATE_DIR` or `~/.moltbot`) using the `env` block, though environment variables are preferred for security:
+
+```json5
+{
+ "env": {
+ "ANTHROPIC_API_KEY": "sk-ant-...",
+ "OPENAI_API_KEY": "sk-..."
+ }
+}
+```
+
+See [Model Providers](/concepts/model-providers) for a complete list of supported providers and their configuration.

-- Whether the container runs locally with `docker build && docker run`
+If Render is configured with `healthCheckPath: /health`, it expects a 200 from `/health` within 30 seconds. This blueprint does not set a health check by default. If deploys fail, check deploy logs and that `scripts/render-start.sh` runs correctly (config written under `MOLTBOT_STATE_DIR` or `~/.moltbot`, then gateway started with the token).
