About Ladybird
Ladybird is a truly independent web browser and browser engine, written from scratch in C++ rather than as a fork of any existing engine, and it is built for developers who want to work on a browser engine based on web standards while it remains in a pre alpha state.

About peerjs
PeerJS is an open source library that provides a complete, configurable, and easy to use peer to peer API built on top of WebRTC. It lives in the JavaScript and TypeScript ecosystem, is written in TypeScript, and is distributed under the MIT license. The library supports both data channels and media streams, so applications can send arbitrary messages between browsers or negotiate audio and video calls without routing traffic through a central media server.
