GrpcBridge

GrpcBridge connects Unreal Engine to gRPC microservices. Generate wrappers for your protos, call remote procedures asynchronously and validate service URIs - from C++ or Blueprints..

Generate wrappers for your .proto services, create a channel, and call remote procedures through async conduits that deliver results back without blocking the game thread. Channel credentials support secure connections, URI validation catches endpoint mistakes early, and the whole flow is reachable from Blueprints or clean C++.

gRPC is the standard for typed microservice APIs, and GrpcBridge plugs Unreal straight into that world: authentication and inventory services, matchmaking and progression backends, internal studio tooling, and dedicated-server-to-service meshes on Windows and Linux where contract-typed calls beat hand-rolled REST.

GrpcBridge 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:

- gRPC channel and RPC client management

- Casts-based async request/response conduits

- Service wrapper code generation

- URI validation helpers

- Windows and Linux dedicated-server friendly

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