## Summary
Lightpanda 1.0 exits beta after two years and over 10,000 commits, marking the project's first production-ready release. The AGPL-3.0 licensed browser is purpose-built for automation, web scraping, and AI agent integration, omitting graphical rendering entirely. It passes 1.74 million Web Platform Tests subtests and maintains compatibility with Puppeteer, Playwright, Selenium, and ChromeDP via the Chrome DevTools Protocol.

## What Lightpanda 1.0 delivers
- **Web Platform Tests**: 1,739,845 subtests passed (up from 2,645 in November 2024), approximately 80% of Chrome's ~2.18 million total
- **JavaScript engine**: V8 15.5.35.13 for JS execution
- **Security hardening**: CORS enforced by default for JS requests, stricter cookie handling, credential leak protection on cross-origin redirects, optional private network blocking
- **Supported APIs**: Shadow DOM, IndexedDB, WebSockets, workers, forms
- **Integration**: MCP server built-in for AI agents; installable via npm or pip
- **Production scale**: Some deployments processing 30+ million pages daily

## Why it matters
Lightpanda offers a fully open-source alternative to Chromium-based headless browsers for automation workloads, with some companies already running it at scale. Its MCP server support positions it for growing AI agent use cases.
