What Hacker News says?
The website is filled with popups and looks ugly IMO No benchmarks shown so claim "the fastest" looks weird No actual *browser* competitors listed e.g. https://lightpanda.io/

HN discussionThanks for the feedback, we will try to make this clearer on the website. Lightpanda works with Playwright, and we have some docs[1] and examples[2] available. Web APIs and CDP specifications are huge, so this is still a work in progess. Many websites and scripts already work, while others do not, it really depends on the case. For example, on the CDP side, we are currently working on adding an Accessibility tree im…

HN discussionHi, I am Francis, founder of Lightpanda. We wrote a full article explaining why we choose Zig over Rust or C++, if you are interested: https://lightpanda.io/blog/posts/why-we-built-lightpanda-in-... Our goal is to build a headless browser, rather than a general purpose browser like Servo or Chrome. It's already available if you would like to try it: https://lightpanda.io/docs/open-source/installation

HN discussionI'm a bit surprised that with all this, they still stuck with Chromium. We have a much less sophisticated setup in our web-access MCP server[0] where browser instances are spawned as subprocesses and the biggest win in stability, CPU and memory usage we had was in switching from Chrome to Lightpanda[1]. Fitting to the statement at the end of the article, the faster browser to boot might be one that allocates less me…

HN discussionYes, this is why I wrote this comment. I did some (really shallow) research and there is lightpanda that seams a bit better solution to search the web from some agent than some wrapper around the Chrome Developer Tools. https://lightpanda.io/docs/open-source/usage
