Love it! From first principles: this kinda answers the "do we really even need CDP" I always have in my head building browser use...

Why go this route? Why Python is more powerful than JS is mostly because of third party plugins like pandas which are excplicitly not supported (C bindings, is this possible to fix?)...

At that point it might be just easier to convince the model to write JS directly

Creator of Browser Use here, this is cool, really innovative approach with ARIA roles. One idea we have been playing around with a lot is just giving the LLM raw html and a really good way to traverse it - no heuristics, just BS4. Seems to work well, but much more expensive than the current prod ready [index]

Show HN: Open-Source Browser Use LLM (30B, A3B)

gregpr07 — Fri, 19 Dec 2025 18:20:30 +0000

Our first model brings SoTA Browser Use capabilities in a small and fast model that can be hosted on a single GPU. It’s much much faster than anything out there and around 15x cheaper than Sonnet 4.5.

The wonderful name comes from: 30B parameters, 3B active, SoTA quality at real-time speed (and the model is based on Qwen/Qwen3-VL-30B-A3B-Instruct).

This model is heavily trained to be used with browser-use OSS library and provides comprehensive browsing capabilities with superior DOM understanding and visual reasoning.

Hey HN,

we heard a lot of complaints about Browser Use being slow. Last few weeks we focused a lot on improving the speed, while keeping the same accuracy.

Go try it out. It's really fun to see it glide the web.

Browser Use creator here; we are working on prototypes like this but always find ourselves stuck with the safety vs freedom questions. We are very well aware how easy it is to inject stuff into the browser and do something malicious hence sandboxed browser still seem to like a very good idea. I guess in the long run we will not even need browsers, just a background agent that does stuff in the background. Is there any good research for guardrails of how to prevent “go to my bank and send the money to nigerian prince” style prompts?

AGI was just 1 bash for loop away all this time I guess. Insane project.

I really like both nodriver and pydoll. I am definitely keeping the option of switching to them open, but we just wanted to have full control for now and see how painful CDP-use is to maintain first and then reconsider.

I mean... Playwright was built and is maintained by Microsoft, so I don't think VC money argument really makes sense here.

By the very nature of how Playwright is built we can't contribute to it - it runs inside a JS subprocess and does not expose a bunch of CDP apis that we NEED (for example to make cross origin iframes work).

Hi, the first version of Browser Use was actually built on Selenium but we quite quickly switched to Playwright

From my experience with Playwright RR-Web recordings are MUCH better than Playwright’s replay traces, so we usually just use those.
