Moon

A hobby web browser developed from scratch

What is this?

This is a web browser developed from scratch using Rust. To fit with the "make from scratch" spirit, the development of the browser avoids the use of external libraries as much as possible.

Wanna try it out?

First, make sure you have all the right dependencies installed:

sudo apt install build-essential cmake pkg-config libssl-dev mold

Then it's just as simple as:

1. Clone the repository.
2. Run cargo run and wait for the code to compile & execute.

Check out the Getting Started Guide for more advanced stuff.
