Had a blast seeing what people built with Lightpanda this weekend {Tech: Europe} hackathon in Paris My (totally unbiased) favourite was Action Cache, who built smarter caching for faster browser agents on Lightpanda Weaviate AI Database and OpenAI Repo below

We’re in STATION F’s Future 40 2025! We’re chuffed. Part of the 1% of startups shaping what’s next in tech from the world’s biggest startup hub Thanks to everyone who’s been in the trenches with us testing, breaking things & building a faster web for machines 🐼⚡

Stop comparing Puppeteer vs Playwright Start asking: "How close to CDP do I need to be?" We broke down the abstraction layers, performance differences, and when to skip CDP entirely lightpanda.io/blog/posts/cdp…

Meanwhile in Paris, Pierre Tachoire hacking with the team Botify HQ

⚠️ We built Lightpanda to fix your broken web automation strategy The web shifted to JavaScript everywhere. Current options: 1. HTTP requests: fast, cheap, insufficient on most sites 2. Browser automation: works, but slow and expensive to scale lightpanda.io/blog/posts/the…

CDP powers the whole web automation ecosystem: Playwright, Puppeteer, Stagehand 🤘, Browser Use & more But it was built for debugging, not automation. And thinks in pixels, not in DOM actions. This forces every lib into workarounds lightpanda.io/blog/posts/cdp…

We started building in Zig 3 years ago This week, Anthropic bet on Zig with their acquisition of Bun We're extremely bullish on this language We wrote up everything we've learned building a browser in Zig ⤵️ lightpanda.io/blog/posts/why…

BYOP to Lightpanda

We've been busy cooking 🧑‍🍳⚡️️ ICYMI... introducing zigdom We ripped out LibDOM and Netsurf's HTML5 parser, rebuilt our DOM from scratch in Zig and switched to Servo's html5ever Here's what it took ⤵️ lightpanda.io/blog/posts/mig…

Some people said nice things about our browser kernel written in Zig. So we put it on the website

Two major objections we never had a great answer for. Until now. 1. Network time will erase your gains 2. At scale, you use tabs not processes So we built a new benchmark on 933 demo pages over the network with JS required 16x less memory and 9x faster lightpanda.io/blog/posts/fro…

Another week, another "I vibe coded a browser" emsh.cat/one-human-one-… I can tell you that to do this properly is not easy. I've been building one for *months* in Zig with AI coding going through the trouble of getting it WPT compliant. It's not easy.

We just shipped a v1 of Stagehand 🤘 compatibility Example code here github.com/lightpanda-io/… ⚠️ you need to create a new page using `const page = await stagehand.context.newPage();`

We just shipped robots.txt support 🤖 Pass --obey_robots and Lightpanda checks and respects robots.txt before making any requests We want Lightpanda to be the default browser for machines and that means giving developers the tools to make machine traffic a good citizen of the

Fun fact: when you load a webpage, your browser makes hundreds of requests and most of them you didn't ask for 👀 Request interception lets you hijack any of them. Block, modify, fake entirely Browser building 101 and a rabbit hole 🕳️ Pierre Tachoire explains how we built it 👇

Frame support just shipped 🖼️ - Each iframe now gets its own JS execution context - CDP is frame-aware - Load events block correctly until all frames resolve - Nested frames work too A lot of the real web lives inside iframes. This was a real gap ⚡️🤗 PR #1565 →

Two huge releases today 1. Native HTML → markdown conversion. Built in Zig. Inside the browser. 2. Launching LP: our own CDP domain extending the protocol with commands built for automation and agents Our conversion happens at the DOM level after JS executes. Actual

agent-browser v0.17 is out → Lightpanda browser engine: --engine lightpanda → Dialog dismiss command → Better daemon error reporting → Auth cookie persistence in native mode → Fixed native auth login encryption npm i -g agent-browser
