OpenClaw on Cloudflare Workers
Run OpenClaw (formerly Moltbot, formerly Clawdbot) personal AI assistant in a Cloudflare Sandbox.

> Experimental: This is a proof of concept demonstrating that OpenClaw can run in Cloudflare Sandbox. It is not officially supported and may break without notice. Use at your own risk.

Requirements
- Workers Paid plan ($5 USD/month) — required for Cloudflare Sandbox containers. Running the container incurs additional compute costs; see [Container Cost Estimate](#container-cost-estimate) below for details.
- Anthropic API key — for Claude access, or you can use AI Gateway's Unified Billing
The following Cloudflare features used by this project have free tiers:
- Cloudflare Access (authentication)
- Browser Rendering (for browser navigation)
- AI Gateway (optional, for API routing/analytics)
- R2 Storage (optional, for persistence)
Container Cost Estimate
This project uses a standard-1 Cloudflare Container instance (1/2 vCPU, 4 GiB memory, 8 GB disk). Below are approximate monthly costs assuming the container runs 24/7, based on Cloudflare Containers pricing:
| Resource | Provisioned | Monthly Usage | Included Free | Overage | Approx. Cost | |----------|-------------|---------------|---------------|---------|--------------| | Memory | 4 GiB | 2,920 GiB-hrs | 25 GiB-hrs | 2,895 GiB-hrs | ~$26/mo | | CPU (at ~10% utilization) | 1/2 vCPU | ~2,190 vCPU-min | 375 vCPU-min | ~1,815 vCPU-min | ~$2/mo | | Disk | 8 GB | 5,840 GB-hrs | 200 GB-hrs | 5,640 GB-hrs | ~$1.50/mo | | Workers Paid plan | | | | | $5/mo | | Total | | | | | ~$34.50/mo |
Notes:
- CPU is billed on active usage only, not provisioned capacity. The 10% utilization estimate is a rough baseline for a lightly-used personal assistant; your actual cost will vary with usage.
- Memory and disk are billed on provisioned capacity for the full time the container is running.
- To reduce costs, configure
SANDBOX_SLEEP_AFTER(e.g.,10m) so the container sleeps when idle. A container that only runs 4 hours/day would cost roughly ~$5-6/mo in compute on top of the $5 plan fee. - Network egress, Workers/Durable Objects requests, and logs are additional but typically minimal for personal use.
- See the instance types table for other options (e.g.,
liteat 256 MiB/$0.50/mo memory orstandard-4at 12 GiB for heavier workloads).
What is OpenClaw?
OpenClaw (formerly Moltbot, formerly Clawdbot) is a personal AI assistant with a gateway architecture that connects to multiple chat platforms. Key features:
- Control UI - Web-based chat interface at the gateway
- Multi-channel support - Telegram, Discord, Slack
- Device pairing - Secure DM authentication requiring explicit approval
- Persistent conversations - Chat history and context across sessions
- Agent runtime - Extensible AI capabilities with workspace and skills
This project packages OpenClaw to run in a Cloudflare Sandbox container, providing a fully managed, always-on deployment without needing to self-host. Optional R2 storage enables persistence across container restarts.
Architecture

Quick Start
_Cloudflare Sandboxes are available on the Workers Paid plan._
# Install dependencies npm install # Set your API key (direct Anthropic access) npx wrangler secret put ANTHROPIC_API_KEY # Or use Cloudflare AI Gateway instead (see "Optional: Cloudflare AI Gateway" below) # npx wrangler secret put CLOUDFLARE_AI_GATEWAY_API_KEY # npx wrangler secret put CF_AI_GATEWAY_ACCOUNT_ID # npx wrangler secret put CF_AI_GATEWAY_GATEWAY_ID # Generate and set a gateway token (required for remote access) # Save this token - you'll need it to access the Control UI export MOLTBOT_GATEWAY_TOKEN=$(openssl rand -hex 32) echo "Your gateway token: $MOLTBOT_GATEWAY_TOKEN" echo "$MOLTBOT_GATEWAY_TOKEN" | npx wrangler secret put MOLTBOT_GATEWAY_TOKEN # Deploy npm run deploy
After deploying, open the Control UI with your token:
https://your-worker.workers.dev/?token=YOUR_GATEWAY_TOKEN
Replace your-worker with your actual worker subdomain and YOUR_GATEWAY_TOKEN with the token you generated above.
Note: The first request may take 1-2 minutes while the container starts.
> Important: You will not be able to use the Control UI until you complete the following steps. You MUST: > 1. [Set up Cloudflare Access](#setting-up-the-admin-ui) to protect the admin UI > 2. [Pair your device](#device-pairing) via the admin UI at /_admin/
You'll also likely want to [enable R2 storage](#persistent-storage-r2) so your paired devices and conversation history persist across container restarts (optional but recommended).
Setting Up the Admin UI
To use the admin UI at /_admin/ for device management, you need to: 1. Enable Cloudflare Access on your worker 2. Set the Access secrets so the worker can validate JWTs
1. Enable Cloudflare Access on workers.dev
The easiest way to protect your worker is using the built-in Cloudflare Access integration for workers.dev:
1. Go to the Workers & Pages dashboard 2. Select your Worker (e.g., moltbot-sandbox) 3. In Settings, under Domains & Routes, in the workers.dev row, click the meatballs menu (...) 4. Click Enable Cloudflare Access 5. Copy the values shown in the dialog (you'll need the AUD tag later).…
