Local-first collaboration platform combining real-time chat, rich text pages, databases, and file management in a single self-hostable workspace.

Colanode brings together the tools teams usually juggle across multiple apps: messaging, documents, wikis, databases, and file storage. It's a single workspace you can self-host and fully control, making it a practical Notion alternative and Slack alternative for teams that don't want their data living on someone else's servers.
The local-first architecture is what sets it apart. Changes save to your device first and sync in the background, so the app stays fast and responsive even on a spotty connection. Conflict-free collaboration is handled through CRDTs (Conflict-free Replicated Data Types), the same technology that powers tools like AnyType and AppFlowy, meaning multiple people can edit simultaneously without stepping on each other's work.
Key capabilities include:
You can self-host the whole thing or use a cloud option. The workspace model means you only enable the features your team actually needs, rather than paying for a bundle of tools you'll ignore. Teams that want data sovereignty without stitching together separate tools for chat, docs, and project tracking will find it covers most of that ground in one place.
