pip install lightpanda gives you a headless browser and its Python bindings in one command, browser included. Scrape JavaScript-rendered pages and hand the data straight to pandas.

The same scraping tasks written as PandaScripts and as Puppeteer and Playwright scripts. Nearly identical code, 4x to 17x less memory, and one binary instead of two processes and a protocol.

Lightpanda is a browser for machines, from agents acting on behalf of a user to data extraction at scale and indexing. Best practice looks different according to your use case.

agent-browser drives Lightpanda over CDP with a one-flag switch. Here is how to get the most out of the integration, plus a demo script you can run today.

We learned that an agent’s tools matter more than its engine. We rebuilt our tool surface: the MCP is now far faster and more accurate, and a native agent built into the binary is faster still.

Just config hookup, as the Frame._notified_network_almost_idle already exists (and is used by CDP).

We ran Lightpanda, agent-browser, and browser-use through AssistantBench and GAIA Level 1 with Claude Sonnet 4.6 as the brain. The tool surface mattered more than the engine.
