RealtimeIO

RealtimeIO connects Unreal to the Socket.IO ecosystem. Emit events, listen for server pushes and move structured JSON both ways - ideal for lobbies, chat, dashboards and live services.

Connect to your Socket.IO server, then Emit events with JSON payloads and Bind handlers for the events your backend pushes - the familiar Socket.IO model, natively in Unreal. The bundled JSON toolkit converts between Blueprint values and wire payloads, namespaces are supported with normalization helpers, and an editor module keeps iteration smooth while you develop.

Socket.IO powers a huge ecosystem of realtime web backends, which makes RealtimeIO the fast path for lobbies and matchmaking, in-game chat, live event broadcasts, second-screen apps, collaborative tools and dashboards - anywhere your Unreal client should react instantly to server pushes.

RealtimeIO is part of the Alpha XP networking collection for Unreal Engine 4.27-5.0+. Every feature is exposed to both Blueprints and C++, ships with styled HTML documentation, and follows one consistent API style across the whole collection. The plugin is compiled and verified against a clean UE 4.27 project, comes with a utility node pack (hashing, GUIDs, timestamps, tokens, validation), and is maintained under the Alpha XP brand with documentation hosted online.

Key Features:

- Socket.IO protocol client (websocket transport)

- Emit/On event model in Blueprints and C++

- Rich JSON object/value toolkit

- Namespace support with normalization helpers

- Editor module for smooth iteration

- Utility node pack: CRC32/MD5/SHA-1 hashing, GUIDs, timestamps, random tokens and hostname validation
