About Stoat

This repository contains the services and libraries that power the Stoat chat service, whose earlier name Revolt still appears in the project's topics. It is a backend codebase written in Rust, using MongoDB for storage and Redis alongside it. The linked developer site documents the public API for people building on the platform.

The code is organized into core crates and server crates. The core crates cover configuration, the database implementation, file handling with S3 storage and encryption, API models, permission logic, user presence, shared result and error types, and a request coalescing service. On top of these sit a REST API server called delta and a WebSocket events server called bonfire.

Key features

REST API server for the chat service
WebSocket events server for real-time updates
Permission logic as a separate crate
S3 file storage with encryption helpers
User presence tracking
