Lightpanda is a headless browser, written from the ground up in Zig, that AI agents and automation scripts use to load and read web pages.
In plain words
A headless browser runs with no visible window, so programs rather than people use it. Lightpanda is a new browser, not a modified Chromium or WebKit, and it skips drawing pages on screen. In its makers' test of 933 real web pages, it used about 16 times less memory than Chrome and finished about 9 times faster. Puppeteer and Playwright scripts can drive it through its CDP server, and it also has an agent mode. Its code uses the AGPL-3.0 licence.
A quick example
Imagine an AI agent that has to check the price on 500 product pages. It connects to a Lightpanda server, opens each page in turn and reads the text it needs, with no browser window ever appearing.
