# Rocket.Chat

Self-host team chat, huddles, and apps without Slack's per-seat meter.

**Replaces:** Slack

**Tier:** Easy

## Problem

Slack Pro is a seat tax on every human who so much as posts. History, huddles, and apps live in a vendor you cannot air-gap. Rocket.Chat is the open-source workspace chat already in the catalog.

## Estimated SaaS cost saved

| You stop paying | Typical / year | Self-host instead |
|---|---:|---|
| Slack Pro (10 seats) | $2,100 | Rocket.Chat on Railway |

**About $2,100 / year** on a small team, before you count lock-in.

## Deploy on Railway

Placeholder: Rocket.Chat + MongoDB (or the project's bundled DB) as a Railway service with a volume. Point WEBHOOK/ROOT_URL at the public domain.

## AGENT_PROMPT

```
Replace Slack with self-hosted Rocket.Chat.

- Persist Mongo/uploads on a volume. Bind HTTP to 0.0.0.0:$PORT.
- Set ROOT_URL to the Railway public domain. Turn off public registration after the first admin.
- Document how to import Slack export (or rebuild the 5 channels that matter).
- Write AGENT_PROMPT.md and a cost table vs Slack Pro seats.
```

## FAQ

### Is this a 1:1 Slack clone?

Channels, DMs, files, and apps, yes. Marketplace bots you will rebuild. Most teams migrate the rooms they actually use and leave old Slack links until they rot.
