**APIs profiled:** 3

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.
