Questions
Frequently asked
What is Lightpanda?
Lightpanda is a headless browser engine built from scratch using the Zig programming language, designed specifically for automation, web scraping, and AI agent workflows. Unlike traditional browsers like Chrome, it focuses exclusively on JavaScript execution without graphical rendering overhead, delivering 9x faster execution and using 16x less memory than Chrome-based solutions.
Is Lightpanda free?
Yes, Lightpanda offers a free Explorer tier that includes 10 browser hours per month with 5 concurrent sessions and community support via Discord. For production workloads, the Builder plan costs $19/month for 300 hours, then $0.08 per additional hour. Enterprise plans with custom pricing are also available.
Can I use my existing Puppeteer or Playwright scripts with Lightpanda?
Yes, Lightpanda is designed to work with existing Puppeteer and Playwright automation scripts with minimal code changes. You can input your current automation scripts and run them on Lightpanda's engine while benefiting from the improved performance and reduced memory usage.
How much faster is Lightpanda compared to Chrome?
According to benchmarks running 933 real web pages on AWS EC2 instances, Lightpanda delivers 9x faster execution times and consumes 16x less memory compared to Chrome-based solutions. This performance improvement comes from eliminating the rendering pipeline and building the engine specifically for machine-driven tasks rather than human users.
What makes Lightpanda different from other browser automation tools?
Lightpanda builds a completely new browser engine from scratch rather than wrapping existing Chrome APIs. This Zig-based architecture eliminates persistent state and cookie management issues that create security vulnerabilities in traditional browsers, providing isolated environments for each automation task without the legacy overhead of browsers designed for human users.
Can I deploy Lightpanda on my own infrastructure?
Yes, Lightpanda supports both cloud-hosted and self-hosted installations. Enterprise plans include on-premise deployment options and private cloud configurations. You can also bring your own proxy configurations across all pricing tiers.
How many concurrent sessions can I run with Lightpanda?
The number of concurrent sessions depends on your plan: the free Explorer tier allows 5 concurrent sessions, the Builder plan supports 30 concurrent sessions, and Enterprise plans offer custom configurations based on your volume requirements.
What programming language is Lightpanda built with and why does it matter?
Lightpanda is built entirely from scratch using the Zig programming language. This choice allows for a lightweight, efficient browser engine without the decades of legacy code found in traditional browsers like Chrome, resulting in faster startup times and significantly reduced memory consumption for automation tasks.
