Foam

Foam is a personal knowledge management and sharing system (note-taking app) inspired by Roam Research, built on Visual Studio Code and GitHub. You can use Foam for organising your research, keeping re-discoverable notes, writing long-form content and, optionally, publishing it to the web. Foam is free, open source, and extremely extensible to suit your personal workflow. You own the information you create with Foam, and you’re free to share it, and collaborate on it with anyone you want. https://foambubble.github.io/foam/
