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 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., lite at 256 MiB/$0.50/mo memory or standard-4 at 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
