A headless browser engine written from scratch in Zig for agents: ~11x faster and ~9x lighter than headless Chrome, CDP compatible with Playwright and Puppeteer, open source with a drop-in managed cloud. The engine layer of the agent browser stack; currently beta.

Lightpanda is a headless browser engine built from scratch in Zig for AI agents and automation: not a Chromium fork or WebKit patch, but a new engine that strips out everything an agent never uses (GPU compositor, extension runtime, full rendering pipeline) and keeps JavaScript execution, DOM access, and the network stack.

The company's own benchmark (chromedp requesting 933 real pages on an AWS m5.large) shows roughly 11x faster execution and 9x lower memory than headless Chrome, with instant startup; third party analyses describe around 8MB per instance versus roughly 200MB for Chrome, enabling thousands of concurrent instances per machine, and report built in anti detection capabilities whose success varies by target. It stays compatible with Playwright, Puppeteer, and chromedp via CDP, and the commercial managed cloud is a drop in swap: point puppeteer.connect at a Lightpanda WebSocket endpoint.

The engine is open source (13K+ stars) and in beta with partial Web API coverage, positioned for high concurrency scraping, agent navigation, LLM training data collection, and lightweight testing where full rendering is unnecessary. Lightpanda is the engine layer of the agent browser stack, which its focused grid profile reflects.

What is public

The open source engine is publicly free to self host; managed cloud rates behind the token endpoints were not captured in retrieved materials.

Variable cost rationale

The product's core pitch is collapsing per instance resource cost (roughly 9x lower memory than Chrome), so browser fleet spend scales gently with volume whether self hosted or cloud.
