## What it is
Let's Chat is a self-hosted, persistent team chat application built on Node.js and MongoDB, designed for small teams. It supports multiple rooms, private/password-protected rooms, file uploads, LDAP/Kerberos authentication, XMPP support, a REST-like API, and Hubot integration.

## Use cases
- self-host a team chat app instead of Slack
- run an internal chat server with LDAP authentication
- chat with XMPP support and persistent message history
- deploy a small-team messaging app on Docker or Heroku
- integrate a chat bot via Hubot adapter
- search chat transcripts and history

## When to choose
- you want full control of your chat data on your own server
- your team needs LDAP or Kerberos single sign-on
- you need XMPP interoperability or a REST API for chat
- you prefer a lightweight chat for a small, intimate team

## When to avoid
- you need modern real-time features like video calls or threads
- you want a large active community and frequent updates
- you need enterprise-scale chat with thousands of users
- you require official mobile apps
