The first browserfor machines, not humans
A fast, lightweight browser engine for automation, crawling and AI agents. JavaScript execution, no graphical rendering.
AI agents
deserve a 100x better web browser
Built from scratch
Not reliant on existing browsers.
Created with Zig
Developed in a low-level system programming language designed for performance and efficiency.
Focused and opinionated
Purpose-built for headless operation, without rendering overhead.

Integrated into leading agent frameworks
Web automation is being held back
Web browsers lack the speed, durability, and security for AI workloads.
Chrome wasn’t built for the cloud
- Running Chrome in the cloud is expensive and slow.
- You’re paying for decades of code built for people, not systems.
Browsers are slow and brittle
- Real-time automation shouldn't wait for browsers.
- Chrome takes seconds to start, which multiply across every process.
Shared state is a security risk
- Automation needs isolated environments.
- Traditional browsers carry persistent state, cookies & sessions across tasks.

@lightpanda_io is going to change the world. I'm calling it!!! I don't understand why i don't hear anything about their browser. - CDP support - most features you need are already supported - most websites already work - insanely low memory use - insanely fast WHAT?

The performance comparison between chrome headless is super promising! github.com/lightpanda-io/…

@AtenKrotos
Super excited for @lightpanda_io

@arjunz
Memory footprint of @lightpanda_io browser, wow
Guillermo Rauch
@rauchg
I’ve done it but speaking of cost efficiencies you’ll probably be better off with a specialized cloud browser runtime like @browserbasehq or @lightpanda_io

An open source headless browser rewritten in Zig designed for AI and automation. • 9x less memory footprint than Chrome • 11x faster execution than Chrome Very exciting times.
Awesome kid

⚡️“I chose Zig because I'm not smart enough to build a big project in C++ or Rust.” - @bouvierfrancis This article is a fantastic deep dive into why you might want to build your next project in Zig #zig

Lightpanda is a cool one that just announced too. Also @steeve ZML!

@steipete
Huh, they wrote a completely new browser in Zig. github.com/lightpanda-io/…

I think you can reduce your server cost much!!! By using lightpanda. https://github.com/lightpanda-io/browser I came accross it in github. And it goes perfectly with puppeteer.

@levelsio try to replace chromium with lightpanda - it's faster and still compatible with puppeteer! github.com/lightpanda-io/…

Finally got a data scraper job working I wanted to try out for a while with lightpanda.io pretty neat. Using the hosted service for now but no reason to believe this would not work equally well locally for some sort om MCP setup for instance.
一丝不go
@yisibl
OMG! Not based on Chromium, Blink or WebKi? Is this a brand new browser kernel written in zig?

@b_arbaretier
So bullish on lightpanda MUCH NEEDED missing block also... 🇫🇷

We use @lightpanda_io for the headless requests in our @amanni_xyz browser. It’s currently the fastest and most efficient solution for agent-based navigation.
Cloud Offer
Engineered for your workflows
Scale effortlessly with your existing tools (Puppeteer, Playwright)
Lightpanda innovation,
Chrome reliability
Choose from Chrome or Lightpanda's browser to ensure all use cases are covered
import puppeteer from "puppeteer"
// Replace puppeteer.launch with puppeteer.connect.
const browser = await puppeteer.connect({
browserWSEndpoint: "wss://euwest.cloud.lightpanda.io/ws?token=YOUR_TOKEN",
})
// The rest of your script remains the same.
const page = await browser.newPage()About Lightpanda
Building a web browser from scratch is a monumental challenge, one that few have attempted.
We took it on because automation and AI demand a fresh foundation, not wrappers on a legacy tech stack.
At our previous company, we scraped millions of web pages a day, and spent years navigating the pain of scaling scraping infrastructure with Chrome.
We knew the only real solution was to start over.
Lightpanda is here to change the game. We want to enable developers and businesses to do more with less.
We're building something ambitious and unconventional.
