Dendrite
Dendrite is a second-generation Matrix homeserver written in Go, designed to handle room management, federation, and client API traffic for real-time communication. It implements the Matrix protocol for federated messaging, presence, and encrypted communication, and can be deployed as a self-hosted platform that manages user accounts, rooms, media, and end-to-end encryption.
The server uses a modular architecture where independent components communicate through an internal message bus, supporting federation with remote homeservers, full-text search indexing of message content, presence broadcasting, and signing key management for authenticating federation requests. It provides user account creation and profile management, including device registration and credential handling, and supports user self-registration directly from client applications.
Dendrite offers deployment options including Docker containers and Kubernetes Helm charts, with configuration for database connection limits, file descriptor limits, message queue backends, and domain name setup. It includes administrative tools for user management, room purging, search reindexing, device refresh, and system notice delivery, as well as performance profiling tools for CPU and memory analysis. The server supports TLS certificate acquisition, DNS resolution caching, and reCAPTCHA verification for spam prevention.
