Lightpanda is a headless browser built from scratch in Zig specifically for speed. We're talking 10-50x faster than Chromium-based headless browsers for page loading and JavaScript execution, at a fraction of the memory.
The target audience is anyone running browsers at scale: scraping pipelines, automated testing farms, AI agents that need to browse the web. When you're paying per minute of compute and per GB of RAM, a browser that uses 90% less of both changes your infrastructure costs dramatically. AGPL-3.0 license. They offer a cloud service alongside the open source browser.
The catch: it's not a full browser. It doesn't render pixels: no screenshots, no visual testing. JavaScript support is growing but not at Chrome-level compatibility. Sites with complex JS frameworks may not work correctly yet. And AGPL means if you modify it and serve it to users, you must open source your changes.
Free vs Self-Hosted vs Paid
free self hosted paid cloudFree (AGPL-3.0): Self-host the headless browser. Full functionality, no feature gates. The AGPL license means modifications must be open-sourced if you offer the browser as a service to others. Internal use is fine.
Paid: Lightpanda Cloud, managed headless browser infrastructure. Pricing on their website. The cloud service likely uses a commercial license that avoids the AGPL requirements.
Self-hosting cost: a VPS with 1-2GB RAM can run it (vs 4-8GB for headless Chrome). At scale, the savings are real. 100 concurrent browser sessions on Lightpanda costs a fraction of what Chromium needs.
The AGPL is the key decision point. If you're building a scraping-as-a-service product, you either open source your stack or pay for the commercial license/cloud.
Free to self-host for internal use. AGPL restricts service use. Cloud option for managed infrastructure.
