Colanode

Colanode is built around a local-first architecture: every change you make is written to a local SQLite database on your device, then synced to the self-hosted server in the background. This means the app stays usable offline and reconciles your changes once connectivity returns. Reads also happen locally, so the UI is responsive even when the server is slow or unreachable.

Concurrent edits are resolved using Conflict-free Replicated Data Types (CRDTs) implemented with the Yjs library. Multiple users can edit the same page or database row simultaneously without overwrites, similar to Notion's collaborative editing. A single Colanode app can also connect to multiple servers, each containing its own set of workspaces.

Colanode bundles four products in one app: real-time chat (1:1 and channels), rich-text pages, structured databases with table, kanban, and calendar views, and file management. The Notion-like editor is paired with a chat and file workspace so teams can keep everything inside a single self-hosted instance. Both web and Electron-based desktop clients are available.

Colanode is released under the Apache License 2.0 and consists of a self-hostable server plus a web or Electron desktop client. You retain full control of your data because everything syncs to your own server rather than a vendor cloud. The stack is TypeScript and Go-based, with around 5,000 stars on GitHub at the time of writing.
