"Cloudflare has introduced Moltworker, an open-source implementation that enables running Moltbot-a self-hosted personal AI agent-on Cloudflare's Developer Platform, removing the need for dedicated local hardware. Moltbot, recently renamed from Clawdbot, is designed to operate as a personal assistant through chat applications, integrating with AI models, browsers, and third-party tools while remaining user-controlled. Moltworker adapts Moltbot to Cloudflare Workers by combining an entrypoint Worker with isolated Sandbox containers."
"The Worker acts as an API router and administration layer, while the Moltbot runtime and its integrations execute inside Sandboxes. Persistent state, including conversation memory and session data, is stored in Cloudflare R2, addressing the ephemeral nature of containers. The implementation leverages recent enhancements in Node.js compatibility within Cloudflare Workers. Cloudflare notes that improved native support for Node APIs reduces the need for workarounds, allowing more npm packages to run unmodified."
"Moltworker integrates several Cloudflare services to replicate and extend the local Moltbot experience. AI requests are routed through Cloudflare AI Gateway, which supports multiple model providers, centralized observability, and options. Browser automation tasks are handled via Cloudflare Browser Rendering, allowing Moltbot to control headless Chromium instances for navigation, form filling, and content capture without running a browser directly in the container. Authentication for APIs and the Admin UI is enforced using Cloudflare Zero Trust Access."
Moltworker ports the Moltbot personal AI agent to the Cloudflare Developer Platform by using an entrypoint Worker alongside isolated Sandbox containers. The Worker handles API routing and administration while runtime processes and integrations run inside Sandboxes. Persistent data such as conversation memory and session state is stored in Cloudflare R2 to counter container ephemerality. The implementation benefits from improved Node.js compatibility in Cloudflare Workers, reducing the need for workarounds and allowing more npm packages to run unmodified. Moltworker leverages Cloudflare AI Gateway for model routing, Browser Rendering for headless Chromium tasks, and Zero Trust Access for authentication, and has drawn mixed early user reactions.
