About Ideon

Ideon is a self-hosted visual workspace for projects. Instead of abstract folders and tabs, it uses spatial organization: you place blocks on a shared infinite canvas, and what sits close together is related, so a project's repositories, design notes and tasks can be seen on a single map.

Blocks can hold Markdown notes, images, links, files and to-dos, and live integrations embed repositories and issues from GitHub, GitLab, Gitea and Forgejo directly on the canvas. Teams can collaborate in real time, and a time travel feature shows historical snapshots of the workspace to trace past decisions. A hosted demo is available to try without setup.

Ideon runs with Docker and Docker Compose, using a PostgreSQL database and a persistent storage volume, and there is a one-click template for the Easypanel deployment platform. You set a secret key in an environment file before starting the stack and open the dashboard on port 3000. It is written in TypeScript and licensed under AGPL-3.0.
