description: Lightpanda is an open-source headless browser built from scratch in Zig
  for AI agents and large-scale automation. It is not a REST API; its programmable
  interface is the Chrome DevTools Protocol (CDP) exposed over a WebSocket endpoint,
  making it a drop-in target for Puppeteer, Playwright, and chromedp clients. It ships
  as an open-source binary/CLI (AGPL-3.0) and as Lightpanda Cloud, a managed CDP
  browser service.

  description: Lightpanda's primary programmable interface. The browser runs as a
    CDP server (`lightpanda serve`) and exposes the Chrome DevTools Protocol over a
    WebSocket endpoint (default `ws://127.0.0.1:9222`). CDP is a bidirectional
    JSON-RPC wire protocol over WebSocket - not a REST API. Existing Puppeteer,
    Playwright, and chromedp scripts connect by pointing `browserWSEndpoint` /
    `connectOverCDP` at this endpoint instead of Chrome.

  description: Managed, hosted CDP browser endpoints reached over secure WebSocket
    (e.g. `wss://euwest.cloud.lightpanda.io/ws`, `wss://uswest.cloud.lightpanda.io/ws`).
    Authentication is a `token` query-string parameter; query parameters such as
    `browser=lightpanda|chrome` and `proxy` select the browser engine and egress.
    Clients connect with the same Puppeteer/Playwright/chromedp CDP tooling. Cloud
    access is request-based; usage pricing is not publicly reconciled.

  description: The open-source command-line binary (AGPL-3.0, written in Zig).
    `lightpanda serve` starts the CDP-over-WebSocket server; `lightpanda fetch`
    retrieves and dumps a URL as HTML or markdown; `lightpanda agent` drives the
    browser with LLM instructions. Distributed via one-line installer, Docker
    images, and nightly Linux/macOS binaries.
