Focalboard is a free, open-source project management tool that works like a self-hosted alternative to Trello, Notion, or Asana. If you've used those tools to organize tasks with boards, cards, and columns, Focalboard does the same thing, but you run it on your own computer or server instead of paying a monthly subscription to someone else's cloud. It comes in two versions: a standalone desktop app for personal use (available on Mac, Windows, and Linux) and a server version that your whole team can use. Both are free. The desktop app is great for individuals tracking personal projects and to-do lists. The server version is for teams who want a shared workspace and prefer to keep their data on infrastructure they control. For founders or small teams who are cost-conscious and comfortable with a bit of setup, Focalboard offers a familiar kanban-board (the column-and-card style of project management made popular by Trello) and more structured Notion-like features, all without a recurring SaaS fee. One important caveat: this standalone version is currently unmaintained, the team behind it has shifted focus to a version that integrates with Mattermost, which is an open-source messaging platform. The code is still here and functional, but no one is actively updating it unless a new community maintainer steps up. For teams already using Mattermost, the Mattermost Boards plugin is the actively supported version.
