Can Stagehand work on a Cloudflare worker + Durable object setup?

[Suman085]

We're considering using Stagehand in a Cloudflare Worker + Durable Object (DO) setup. The Agent, built with agent-sdk, manages WebSocket connections, session state, and interacts with Browserbase to automate browser sessions.

Questions

• Is Stagehand compatible with Cloudflare Worker + Durable Object environments?
• Any best practices or limitations we should consider?

Currently, I am getting this error which I think occurs because of trying to load a native .node module, which is not supported in Cloudflare Workers.

Cloudflare has its own fork of Playwright: https://github.com./cloudflare/playwright, which can be spun up inside a Worker. They also provide their own browser automation solution: https://developers.cloudflare.com/browser-rendering/

I tried running Stagehand on a Cloudflare Worker a few months ago, but it wasn’t possible because Workers are not fully compatible with Node.js and therefore lack the fs module. However, this may change soon: cloudflare/workerd#3796.

So, long story short, as of now, you either use their solution or host it elsewhere.
