Every community needs places to gather, discuss, and work together. In the digital age, these spaces are often rented from corporations—Slack, Discord, Google Workspace, Zoom.

But renting your community's communication infrastructure comes with costs beyond the subscription fee. Your data feeds someone else's business model. Your conversations happen on someone else's terms. Your community's history can disappear if a company changes direction.

Self-hosted collaboration tools offer an alternative: infrastructure your community actually owns.

## Why Self-Hosting Matters

### Data Ownership

On commercial platforms, your community's messages, files, and behavioral patterns feed business models built on knowing everything about you. Organizations working with vulnerable populations can't in good conscience put sensitive information on platforms that monetize data.

When you self-host, your data never leaves your infrastructure. There's no third-party access, no behavioral profiling, no feeding the surveillance economy.

### No Algorithmic Manipulation

Commercial platforms are optimized for "engagement"—keeping users scrolling, clicking, reacting. This often means anxiety, comparison, and compulsive checking.

Community-owned platforms don't need to maximize time on site. They can be designed for actual usefulness and genuine connection. As one community member put it: "There's no algorithm trying to make me angry so I'll keep scrolling."

### Autonomy and Customization

Global platforms are designed for the average of everyone, which means they're perfect for no one. Communities have different needs: a rural cooperative needs different things than an urban advocacy organization.

Self-hosted tools can be customized to fit how your community actually works, not how a product manager in Silicon Valley thinks you should work.

### No Vendor Lock-in

Platforms change their terms. Companies get acquired, pivot, or shut down. Communities have watched years of history disappear when platforms closed.

Your ability to communicate and organize shouldn't depend on anyone else's permission.

## Getting Started

A recommended starter stack for most communities:

- **Nextcloud** for files, calendar, and basic chat
- **Jitsi** for video meetings
- **Discourse** for community discussions

As needs grow, add specialized tools for real-time chat (Mattermost, Zulip) or encrypted collaboration (CryptPad).

The technical barrier is lower than ever. Docker deployments, managed hosting services, and excellent documentation make self-hosting accessible to communities without deep technical expertise.

And the benefits compound: every dollar spent on self-hosted infrastructure builds something your community owns, rather than paying rent to a distant corporation.

Communities that build their own collaboration infrastructure report something unexpected: the technology becomes an excuse for connection. The process of choosing, deploying, and maintaining tools together builds relationships that extend far beyond the technology itself.
