Show HN: I wrote an open-source browser alternative for Computer Use for any LLM (Score: 150+ in 16 hours)

Hey HN,
I made Browser-Use, an open-source tool that lets (all Langchain supported) LLMs execute tasks directly in the browser just with function calling.
It allows you to build agents that interact with web elements using natural language prompts. We created a layer that simplifies website interaction for LLMs by extracting xPaths and interactive elements like buttons and input fields (and other fancy things). This enables you to design custom web automation and scraping functions without manual inspection through DevTools.
Hasn't this been done a lot of times?
Good question, as a general SaaS tool yes, but I think a lot of people are going to try to make their own web automation agents from scratch, so the idea is to provide groundwork/library for the hard part so that not everyone has to repeat these steps:
- parse html in a LLM friendly way (clickable items + screenshots)
- provide a nice function calls for everything inside the browser
- create reusable agent classes
What this is NOT? An all knowing AI agent that can solve all your problems.
The vision: create repeatable tasks on the web just by prompting your agent and not care about the hows.
To better showcase the power of text extraction we made a few demos such as:
- Applying for multiple software engineering jobs in San Francisco
- Opening new tabs to search for images of Albert Einstein, Oprah Winfrey, and Steve Jobs
- Finding the cheapest one-way flight from London to Kyrgyzstan for December 25th
I’d be interested in feedback on how this tool fits into your automation workflows. Try it out and let me know how it performs on your end.
We are Gregor & Magnus and we built this in 5 days.

Show HN: Convert any website into a React component (Score: 150+ in 11 hours)

Comments: https://readhacker.news/c/6hqKJ
Hey HN, we built a Chrome Extension (https://www.magicpatterns.com/extension) that converts a snippet of any website to an isolated React component.
Demo video: https://youtu.be/hutUYDkyE_A
How it works: 1) Iterate through each node in the selected DOM tree, 2) For each element, find any matching CSS selectors / inline styles, 3) Use window.getComputedStyle to get the deterministic values, 4) Construct JSX
It was pretty hard producing the minimal code necessary while maintaining the same visual look. To do this, we implemented things like abstracting out global styles, removing inherited styles, pulling out SVGs, deleting styles with no effect, and condensing styles into their shorthand properties.
We dive into each of those optimizations here for fun: https://www.magicpatterns.com/blog/any-website-to-react-comp...
One of the main reasons we cared so much about condensing down the styles was not only to make it more human-readable, but also to reduce context length for an LLM, so that you can iterate on it with AI. Our extension has a “convert” option that lets you convert the output to Tailwind, Shadcn, or Chakra UI using an LLM. You can also export to Figma.
We're frontend engineers and we built the extension because our core product (https://www.magicpatterns.com/) helps software teams prototype their product ideas. And a huge pain point for users is getting their existing designs into our product, so that they can reference them to generate UIs with their existing aesthetic.
The extension allows you to get existing design context from any website, even localhost. Since launch, the extension has more than 3,000 users and interestingly is most popular in Japan.
Here's some real examples if you're curious what the final output looks like:
A) Hacker News Navbar - https://www.magicpatterns.com/ac9f38e4-5ef0-49e5-8b80-dbc429...
B) ChatGPT Welcome Screen - https://www.magicpatterns.com/7cb3ad12-cb12-4a5b-b32b-eda04d...
C) Cal.com Calendar Component — https://www.magicpatterns.com/a43bac78-134d-458d-8107-811ac7...
D) Stripe.com logo section - https://www.magicpatterns.com/deff1793-7a05-42fe-97f7-945976...
