Lightpanda 1.0 speaks WebDriver, making it the only browser that natively speaks every web automation protocol: CDP, WebDriver and MCP. Run your Selenium scripts on it by changing the driver setup: up to 4.4x faster than headless Chrome, with 7x less memory.
Lightpanda leaves beta with 1.7 million passing Web Platform Tests and CORS on by default. Here's what changed since November 2024.
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.
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.
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.
The browser agent stack, mapped layer by layer: model, harness, browser drivers, engine. Lightpanda covers three of the four in a single binary.
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.
Lightpanda now has a built-in agent. Talk to it in natural language, get a reliable script back. Run that script forever only calling an LLM when it needs fixing.
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.
Lightpanda is now an officially supported browser backend in Nous Research's Hermes Agent. One config line to enable, with automatic Chrome fallback for the gaps.
Zaid Daba'een, CEO & Founder of DeveloperHub.io, switched their prerender deployment to use Lightpanda instead of headless Chrome. Pages now serve 4x faster and load average dropped 10x.
Every tool in web automation runs on a browser engine. There are only two real options: Chromium and Lightpanda. Here's how the entire stack fits together.
Lightpanda now supports Web Bot Auth, the emerging standard for bots and AI agents to cryptographically prove their identity.
The LP domain grows with LP.getSemanticTree, LP.getInteractiveElements, and LP.getStructuredData alongside a native MCP server built into the browser binary that exposes the same engine capabilities without CDP.
Lightpanda now converts web pages to markdown natively inside the browser, cutting token usage for AI agents.
Lightpanda can now handle multiple CDP connections simultaneously. Here's what it took to get there and what it means for running concurrent browser sessions at scale.
Why we added robots.txt support, how the singleflight cache works, and why the feature is opt-in.
