Turms is an open-source instant messaging engine written in Java designed to scale from 100K to 10M concurrent users. It provides a distributed server cluster (gateway, service, and admin components) with client SDKs for Java, JavaScript, and Swift, deployable via Docker Compose or Terraform.
Use cases
- build a chat app for millions of concurrent users
- self-host a private instant messaging server
- add real-time messaging to iOS, Android, and web apps
- deploy a scalable IM backend with Docker or Terraform
- run a group chat and message timeline service
- monitor a messaging cluster with Prometheus and Grafana
When to choose
- you need a highly scalable, distributed IM backend for 100K+ concurrent users
- you want a self-hosted alternative to proprietary chat services
- you need cross-platform client SDKs (Java, JS, Swift) for chat apps
- you want built-in admin tooling and monitoring out of the box
When to avoid
- you need a tiny embedded chat widget with minimal infrastructure
- your team has no capacity to operate a Java-based distributed cluster with MongoDB and Redis
- you only need simple peer-to-peer messaging without server-side features
- you prefer a managed SaaS chat provider over self-hosting
