DataCourier

DataCourier is a transport-agnostic data pipeline for Unreal. Pick a protocol, pick a packet rule, and ship UObjects, JSON or raw bytes between processes, machines and tools with one consistent API.

Pick a transport (TCP client/server, UDP, WebSocket or shared memory), pick a packet rule (size header, terminator, fixed length or none), attach a delivery box if you want automatic UObject-JSON serialization, and start the courier - the same API regardless of the combination. Twenty Blueprint samples plus a test module document every permutation, and utility nodes cover the byte-level odds and ends.

DataCourier shines wherever Unreal must exchange structured data with other processes: editor tools talking to DCC applications over shared memory, simulators streaming state to analysis tools, inter-process game architectures, hardware bridges, and network protocols you would rather configure than hand-write.

DataCourier 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:

- Four transports: TCP, UDP, WebSocket, shared memory

- Pluggable packet rules (size header, terminator, fixed, nodivision)

- JSON delivery boxes serialize UObjects both ways

- 20 Blueprint samples and a test module included

- String/bytes/Base64 utility nodes

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