## Why?
### Javascript execution is mandatory for the modern web
In the good old days, scraping a webpage was as easy as making an HTTP request, cURL-like. It’s not possible anymore, because Javascript is everywhere, like it or not:
- Ajax, Single Page App, infinite loading, “click to display”, instant search, etc.
- JS web frameworks: React, Vue, Angular & others
### Chrome is not the right tool
If we need Javascript, why not use a real web browser? Take a huge desktop application, hack it, and run it on the server. Hundreds or thousands of instances of Chrome if you use it at scale. Are you sure it’s such a good idea?
- Heavy on RAM and CPU, expensive to run
- Hard to package, deploy and maintain at scale
- Bloated, lots of features are not useful in headless usage
### Lightpanda is built for performance
If we want both Javascript and performance in a true headless browser, we need to start from scratch. Not another iteration of Chromium, really from a blank page. Crazy right? But that’s we did:
- Not based on Chromium, Blink or WebKit
- Low-level system programming language (Zig) with optimisations in mind
- Opinionated: without graphical rendering
## Status
Lightpanda is still a work in progress and is currently at a Beta stage.
:warning: You should expect most websites to fail or crash.
Here are the key features we have implemented:
- [x] HTTP loader
- [x] HTML parser and DOM tree (based on Netsurf libs)
- [x] Javascript support (v8)
- [x] Basic DOM APIs
- [x] Ajax
- [x] XHR API
- [x] Fetch API
- [x] DOM dump
- [x] Basic CDP/websockets server
NOTE: There are hundreds of Web APIs. Developing a browser (even just for headless mode) is a huge task. Coverage will increase over time.
You can also follow the progress of our Javascript support in our dedicated [zig-js-runtime](https://github.com/lightpanda-io/zig-js-runtime#development) project.
