Introducing Gosub: A Rust‑Powered Open‑Source Browser Engine

Today I’m excited to introduce Gosub, a brand‑new open‑source browser engine built from the ground up in Rust.

Gosub aims to be a modern, modular, and highly flexible engine. Although it is still in early development, the project is gaining momentum and the team is recruiting more contributors.

GitHub: https://github.com/gosub-io/gosub-engine

The engine strives for high performance, safety, and developer friendliness, adhering to the latest web standards to provide users with more choices and to challenge the dominance of large‑company browsers.

Current components include:

HTML5 tokenizer / parser

CSS3 tokenizer / parser

Document tree

API for connecting JavaScript

Configuration storage

Network stack

Rendering engine

JS bridge

Gosub can already parse HTML5 and CSS3 files and perform simple rendering, making basic web browsing possible.

It can be compiled to WebAssembly, allowing the engine to run inside other browsers and be embedded within Chrome, Firefox, and similar platforms.

Key highlights:

* Written in Rust: Leverages Rust’s safety and performance to create a powerful engine.

* Modular design: Components are organized for clear separation of concerns, easier collaboration, and flexible swapping of parts.

* Collaborative open source: The project welcomes contributions and aims to be more understandable and cooperative than existing browsers.

The team is looking for developers interested in browser technology, regardless of Rust experience, to help with core modules, documentation, and project direction.

In summary, building a browser engine from scratch in Rust is a complex but technically impressive endeavor, offering a potential alternative to the Chrome/WebKit monopoly.
