Hey Anirudh, Stagehand looks awesome, congrats. Really love the focus on making browser automations more resilient to DOM changes. The act, extract, and observe methods are super clean.

You might want to check out Lightpanda (https://github.com/lightpanda-io/browser). It's an open-source, lightweight headless browser built from scratch for AI and web automation. It's focused on skipping graphical rendering to make it faster and lighter than Chrome headless.

This looks really cool, thanks for sharing!

I recently tried to implement a workflow automation using similar frameworks that were playwright or puppeteer based. My goal was to log into a bunch of vendor backends and extract values for reporting (no APIs available). What stopped me entirely were websites that implemented an invisible captcha. They can detect a playwright instance by how it interacts with the DOM. Pretty frustrating, but I can totally see this becoming a standard as crawling and scraping is getting out of control.

Lightpanda does look promising, but this is an important note from the readme: " You should expect most websites to fail or crash."

I've been playing around with Stagehand for a minute now, actually a useful abstraction here. We build scrapers for websites that are pretty adversarial, so having built in proxies and captcha is delightful. Do you guys ever think you'll do a similar abstraction for MCP and computer use more broadly?

Thanks so much! Our Stagehand MCP server actually won Anthropic's Claude MCP hackathon :) Check it out: https://github.com/browserbase/mcp-server-browserbase/tree/m... We're working on a better computer use integration using Stagehand, def a lot of interesting potential there

interesting and hope to see this improve with open source GUI Agent vision model projects like OS-Atlas

You're absolutely right, the 'most websites will fail' note is there because we're still in development, and the browser doesn't yet handle the long tail of web APIs.

That said, the architecture's coming together and the performance gains we're seeing make us excited about what's possible as we keep building. Feedback is very welcome, especially on what APIs you'd like to see us prioritize for specific workflows and use cases.

People must be excited for this since a lot of people are commenting for the first time in months or years to say how much they love it. Some people liked it so much they commented for the first time ever to say how great it is.

wow. It's like cursor vs vscode movement but for browser automation and scrapping. Kudos to the author. Are there any other similar tools?

https://crawlspace.dev has a similar LLM-aware scraping where you can pass a Zod object and it’ll match the schema, but is available as a PaaS offering with queueing / concurrency / storage built in [disclaimer: I’m the founder]

This is 100% the future of UI testing. The dream of BDD and Gherkin can be fully realized now that the actual test code writing/maintenance portion is completely taken care of.

Can it be adapted to use ollama? Seems like a good tool to setup locally as a navigation tool.

Yes, you can certainly use Ollama! However, we strongly recommend using a more beefed up model to get sustainable results. Check out our external_client.ts file in examples/ that shows you how to setup a custom LLMClient: https://github.com/browserbase/stagehand/blob/main/examples/... >

It doesn’t look like accessing the llmclient for this is possible for external projects in the latest release, as that example takes advantage of being inside the project. (At least working through the quick start guide).
