What is Lightpanda?
Lightpanda is a headless browser engine built from scratch in Zig, not as a Chromium fork, for automation, web crawling, and AI agents. It executes JavaScript via V8 and processes the DOM without graphical rendering, and it exposes the Chrome DevTools Protocol so Puppeteer and Playwright can connect to it as a drop-in backend. It's open source under AGPL-3.0 (about 32,000 GitHub stars), self-hostable with a one-line install script, and also available as a managed cloud service.
Our verdict
The no-rendering, non-Chromium design targets speed and memory savings over headless Chrome, and CDP compatibility means existing Puppeteer or Playwright code can often point at it with little change. Because it's a new engine built independently of Chromium, expect gaps in rendering fidelity and edge-case site compatibility that mature Chromium-based tools have already worked through.
Categories:
Browser infrastructure gives you a remote Chrome or Chromium instance over a protocol like CDP or Playwright, so you run automation without managing browser servers. It is the layer many scraping APIs and agent tools build on, and it suits teams that want control of the browser without the operations work.

How Lightpanda compares
BrowserbaseBrowserbase is managed, Chromium-based headless browser infrastructure for the same automation and AI-agent use cases, trading Lightpanda's speed and memory savings for full Chromium rendering fidelity.
BrowserlessBrowserless runs self-hosted or cloud Chromium browser instances for Puppeteer and Playwright automation, a more established Chromium-based alternative to Lightpanda's custom engine.
SteelSteel is another open-source browser infrastructure project built for AI agents, though it runs on Chromium rather than Lightpanda's from-scratch Zig engine.
