Foam: Open-Source PKM Built on VS Code & GitHub

Foam is a free, open-source personal knowledge management (PKM) and sharing system inspired by Roam Research, built on Visual Studio Code and GitHub. It lets you organize research, keep rediscoverable notes, write long-form content, and optionally publish it to the web. Features include bidirectional linking, graph visualization, templating, tagging, and more, helping you build a personal knowledge base with easy navigation and management tools. While still under rapid development, its powerful features and open nature make it a compelling PKM choice.
