Overview

Lightpanda is a headless browser engine written from scratch in Zig for automation, crawling and AI agents. It runs JavaScript but does no graphical rendering. Puppeteer scripts connect to its hosted cloud over a WebSocket endpoint instead of launching a local browser, and that cloud can run either Lightpanda's engine or Chrome.

Best for: Developers running high-volume scraping or AI agent browsing who want lower RAM and start-up cost
Pricing: Free Explorer tier with 10 browser hours a month, then $19/month for 300 hours plus $0.08 per extra hour, with custom pricing for Enterprise.
Runs on: WebSelf-hosted
