## What it is
Dendrite is a second-generation Matrix homeserver written in Go, designed as an efficient, reliable, and scalable alternative to Synapse. It supports small-to-medium deployments and P2P Matrix nodes, and is now maintained by Element at element-hq/dendrite.

## Use cases
- self-host a Matrix chat server
- run a lightweight alternative to Synapse
- host a federated messaging homeserver
- run Matrix nodes in-browser or on mobile via P2P
- deploy a scalable homeserver across multiple machines

## When to choose
- you want a low-memory, efficient Matrix homeserver in Go
- you run a small homeserver (tens to hundreds of users)
- you need P2P Matrix support
- you prefer PostgreSQL-backed homeservers with schema upgrade support

## When to avoid
- you need high-availability or clustering for massive deployments
- you need a fully battle-tested, feature-complete homeserver
- you want the actively developed version - use element-hq/dendrite or Synapse instead

## Facets
- artifact type: service
- maturity: maintenance
- function: http-server, api-framework, websocket, self-hosted
- domain: messaging-platforms, self-hosted, backend, apis
- platform: windows, go, self-hosted, cross-platform
- tags: matrix-homeserver, federation, chat-server, p2p, microservices, linux, macos, docker
