4gaBoards

4gaBoards is a self-hosted kanban and project management app built with React, TypeScript, and Redux, released under the MIT license on GitHub. Where Notion aims to be an all-in-one workspace of docs and databases, 4gaBoards focuses narrowly on a projects → boards → lists → cards → tasks hierarchy with a Markdown editor for card descriptions. Realtime updates are pushed to the browser without a page refresh, and the whole stack runs on your own infrastructure.

The recommended path is the official docker-compose.yml, and the docs also cover Kubernetes, TrueNAS, and a manual install. You will need a PostgreSQL database, a SECRET_KEY generated with openssl rand -hex 64, and a configured BASE_URL. The default image listens on port 3000 and seeds a demo/demo account on first boot so you can verify the install immediately.

Yes — 4gaBoards ships a built-in Trello import that runs when you add a new project, and the Pro plan adds CSV import/export for boards, lists, and cards. A two-way GitHub Issues sync is listed as a feature on the roadmap (Coming soon in the README). There is no first-party Notion importer, so Notion databases have to be exported as CSV first and then re-imported.

The web client is fully realtime — board changes, card moves, and edits push to teammates without page reloads, and you can multitask by editing one card while filtering or rearranging the board elsewhere. Authentication supports SSO via Google, GitHub, Microsoft, and generic OIDC providers, with role-based access for boards and projects. The hosted Pro tier removes the per-user cap and is priced at £6/user/month.
