+# Deploying prompts.chat to Cloudflare Containers
+
+This guide covers deploying the Next.js application to [Cloudflare Containers](https://developers.cloudflare.com/containers/).
+
+## Prerequisites
+
+- [Docker](https://docs.docker.com/desktop/) running locally
+- [Wrangler CLI](https://developers.cloudflare.com/workers/wrangler/install-and-update/) (`npm i -g wrangler`)
+- A Cloudflare account on the [Workers Paid plan](https://workers.cloudflare.com/pricing/)
+- An external PostgreSQL database (e.g. Neon, Supabase, or self-hosted)
+
+## Setup
+
+### 1. Install dependencies
+
+```bash
+npm install @cloudflare/containers
+```
+
+### 2. Configure secrets
+
+Set required environment variables as Wrangler secrets. These are injected into the container at runtime:
+
+```bash
+# Required
+wrangler secret put DATABASE_URL
+wrangler secret put AUTH_SECRET
+
+# OAuth (if using these providers)
+wrangler secret put AUTH_GITHUB_ID
+wrangler secret put AUTH_GITHUB_SECRET
+wrangler secret put AUTH_GOOGLE_ID
+wrangler secret put AUTH_GOOGLE_SECRET
+
+# Optional
+wrangler secret put OPENAI_API_KEY
+wrangler secret put SENTRY_DSN
+```
+
+### 3. Deploy
+
+```bash
+npx wrangler deploy
+```
+
+On the first deploy, Wrangler will:
+1. Build the Docker image locally using `Dockerfile.cloudflare`
+2. Push the image to Cloudflare's managed registry
+3. Deploy the Worker that routes traffic to the container
+
+The first deploy takes a few minutes for image push and container provisioning. Subsequent deploys are faster due to layer caching.
+
+### 4. Check status
+
+```bash
+npx wrangler containers list
+```
+
+## Architecture
+
+```
+User Request → Cloudflare Network → Worker (router) → Container (Next.js on Node.js)
+                                                          ↓
+                                                    PostgreSQL DB
+```
+
+- **Worker** (`cloudflare/worker.js`): Thin routing layer that forwards all requests to the container
+- **Container** (`Dockerfile.cloudflare`): Multi-stage Node.js image running the Next.js standalone server
+- The container runs the full Node.js runtime, so all dependencies (Prisma, next-auth, next-intl, sharp) work without modification
+
+## Configuration
+
+Key settings in `wrangler.jsonc`:
+
+| Setting | Default | Description |
+|---------|---------|-------------|
+| `max_instances` | 3 | Maximum concurrent container instances |
+| `instance_type` | standard-1 | 2 vCPU, 2 GiB memory |
+| `sleepAfter` | 5m | Container sleeps after 5 minutes of inactivity |
+
+Adjust `max_instances` and `instance_type` based on your traffic. See [instance types](https://developers.cloudflare.com/containers/platform-details/#instance-types) for all options.
+
+## Local development
+
+Local development remains unchanged:
+
+```bash
+npm run dev
+```
+
+To test the Docker image locally:
+
+```bash
+docker build -f Dockerfile.cloudflare -t prompts-chat .
+docker run -p 3000:3000 --env-file .env prompts-chat
+```
+
+## Notes
+
+- **Cold starts**: Containers take 2-3 seconds to wake from sleep. The `sleepAfter` setting in `cloudflare/worker.js` controls when idle containers go to sleep.
+- **Database**: Use an external PostgreSQL provider. Cloudflare Hyperdrive can be added for edge connection pooling if needed.
+- **Containers Beta**: Cloudflare Containers is currently in beta. See [beta info](https://developers.cloudflare.com/containers/beta-info/) for limitations.
