Applications
Colanode, a self hosted, local first collaboration workspace that brings team chat, pages and docs, and structured databases together on a server you control.
Overview
Colanode is an open source collaboration workspace that combines real time chat channels, collaborative pages and documents, flexible databases and file sharing in one place, a self hosted alternative to tools like Slack and Notion. It is local first: the desktop and web clients keep a full local copy of your workspaces, so the app stays fast and keeps working offline, then syncs your changes back to the server when you reconnect. Teams organise work into workspaces and channels, write and link rich pages, track anything in databases with custom fields and views, and share files, all under one account on infrastructure you own. Because every workspace lives on your own server, your conversations, documents and files never leave your environment.
Why the cloudimg image
The upstream project defaults to open registration, so cloudimg makes every instance secure by default before the port is ever public. On first boot each instance generates its own database and cache passwords, seeds a single administrator account with a random password written to a root only file, and closes public signup so a fresh server is never world joinable. The workspace is served only through a hardened reverse proxy with an automatically generated certificate, so the browser client runs over a secure connection out of the box, and the application containers and their data stores are bound to the local network rather than exposed directly. Every deployment comes with a paired deploy guide and 24/7 cloudimg support.
Common uses
- Run a private team chat and knowledge base on infrastructure you fully control
- Keep documents, notes and structured databases together in one collaborative workspace
- Give a team a fast local first workspace that keeps working offline and syncs on reconnect
