Fast non-Chromium browser for AI agents: LightPanda

Lightpanda | The headless browser SVG The first browser for machines, not humans 10x faster. 10x less memory. Instant startup. Quickstart Guide No signup needed Web automation is being held back Web browsers lack the speed, durability, and security for AI workloads. IconNoCloud 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. IconSlowBrowser Browsers are slow and brittle Real-time automation shouldn't wait for browsers. Chrome takes seconds to start, which multiply across every process. IconSharedState Shared state is a security risk Automation needs isolated environments. Traditional browsers carry persistent state, cookies & sessions across tasks. 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.

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? Adam @urbanisierung The performance comparison between chrome headless is super promising! github.com/lightpanda-io/… atenkrotos @AtenKrotos Super excited for @lightpanda_io Arjun @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 Sébastien Chopin @Atinux 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 @algonacci benchmarking lightpanda.io built on top of zig vs chrome Viacheslav Biriukov @brk0v ⚡️“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 Mitchell Hashimoto @mitchellh Lightpanda is a cool one that just announced too. Also @steeve ZML! Peter Steinberger @steipete Huh, they wrote a completely new browser in Zig. github.com/lightpanda-io/… Jit @jit_infinity 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. Berlian Gor @berliangor @levelsio try to replace chromium with lightpanda - it's faster and still compatible with puppeteer! github.com/lightpanda-io/… Tijs Teulings @tijs.org bluesky 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? Baudouin @b_arbaretier So bullish on lightpanda MUCH NEEDED missing block also... 🇫🇷 GAM @Gatindogbe 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.

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. Join us. Ambitious. Unconventional. And just getting started IconGithub
