moltworker (cloudflare/moltworker) is Cloudflare’s proof-of-concept for running OpenClaw on Cloudflare Workers and Containers. It is experimental and not officially supported by Cloudflare.
The implementation runs OpenClaw in a Cloudflare Sandbox environment (1/2 vCPU, 4 GiB memory, 8 GB disk). It includes a Chrome DevTools Protocol (CDP) shim for browser automation, optional R2 storage for persistence, Cloudflare AI Gateway integration, and a pre-installed `cloudflare-browser` skill.
Requires the Cloudflare Workers Paid plan ($5/month).
Frequently Asked Questions
What is Moltworker and why did Cloudflare build it?
Moltworker (cloudflare/moltworker) is a proof-of-concept that runs OpenClaw inside Cloudflare Workers and Containers. Cloudflare built it to demonstrate their Containers product â a new offering that lets you run stateful workloads on Cloudflare’s global network. It’s experimental and not officially supported by Cloudflare for production use.
How much does it cost to run Moltworker?
Moltworker requires the Cloudflare Workers Paid plan at $5/month, plus AI provider API costs (OpenAI, Anthropic, etc.). The Cloudflare Container environment provides 1/2 vCPU, 4 GiB memory, and 8 GB disk â generous specs for running a full OpenClaw instance.
What makes Moltworker different from running OpenClaw on a VPS?
Moltworker runs on Cloudflare’s global edge network, meaning low-latency access from anywhere. It also gets built-in integration with Cloudflare AI Gateway (for model routing and cost management), R2 storage for persistence, and a Chrome DevTools Protocol browser shim for web automation tasks â all without needing to configure separate services.
Is the Cloudflare browser shim the same as Puppeteer?
Not exactly. Moltworker’s CDP shim implements the Chrome DevTools Protocol for browser automation, similar to how Puppeteer works. It allows OpenClaw agents to control a headless browser within the Cloudflare sandbox environment, enabling web scraping and UI automation tasks without launching a full Chrome instance.
