deepstream is an open-source realtime server that synchronizes schema-less records, provides publish-subscribe events, and routes RPCs between clients and backend services over WebSockets. It includes pluggable authentication and a permission language (Valve) for fine-grained access control.

Use cases

• sync data between clients in realtime
• build a pubsub messaging backend
• add rpc request-response to a webapp
• realtime collaborative app server
• query which users are online
• secure websocket messaging with permissions

When to choose

• you need fast data-sync, pubsub, and rpc in one self-hosted server
• you want fine-grained per-message permissions and pluggable auth
• you're building realtime web, mobile, or IoT apps at scale

When to avoid

• you only need simple REST APIs without realtime features
• you prefer a managed cloud realtime service
• you need a lightweight message broker without data-sync concepts
