Use Cases & Benefits
- Provides a lightweight, headless browser designed for fast JavaScript execution and web automation using the Chrome DevTools Protocol.
- Delivers ultra-low memory usage and significantly faster startup and execution compared to traditional browsers like Chrome.
- Use for scalable web scraping and data extraction from JavaScript-heavy websites with minimal resource consumption.
- Use for running automated browser tests and scripts in CI/CD pipelines where speed and resource efficiency are critical.
- Use for AI agent workflows and large language model training that require rapid, headless web interactions and API testing.

From the README
Lightpanda is the open-source browser made for headless usage:
Fast web automation for AI agents, LLM training, scraping and testing:
Puppeteer requesting 100 pages from a local website on a AWS EC2 m5.large instance. See benchmark details.
Due to the nature of Playwright, a script that works with the current version of the browser may not function correctly with a future version. Playwright uses an intermediate JavaScript layer that selects an execution strategy based on the browser's available features. If Lightpanda adds a new Web API, Playwright may choose to execute different code for the same script. This new code path could attempt to use features that are not yet implemented. Lightpanda makes an effort to add compatibility tests, but we can't cover all scenarios. If you encounter an issue, please create a GitHub issue and include the last known working version of the script.
Install from the nightly builds
You can download the last binary from the nightly builds for Linux x86_64 and MacOS aarch64.
For Windows + WSL2
The Lightpanda browser is compatible to run on windows inside WSL. Follow the Linux instruction for installation from a WSL terminal. It is recommended to install clients like Puppeteer on the Windows host.
