vtprotobuf is a protoc plugin (protoc-gen-go-vtproto) that generates optimized, reflection-free marshaling and unmarshaling Go code for Protocol Buffers APIv2. It runs alongside the upstream protoc-gen-go generator to produce auxiliary SizeVT, EqualVT, and MarshalVT helpers for faster serialization.

Use cases

• generate faster protobuf marshal code in Go
• speed up gRPC serialization without reflection
• reduce allocations when marshaling protobuf messages
• replace gogo/protobuf with an APIv2-compatible codegen
• generate unrolled Size and Equal helpers for proto messages
• marshal protobuf messages into pooled buffers

When to choose

• you use protobuf APIv2 in Go and serialization is a performance bottleneck
• you want gogo/protobuf-style optimized codegen maintained for APIv2
• you need zero-allocation marshaling or buffer pooling for proto messages

When to avoid

• your protobuf workloads are not performance-sensitive and standard protoc-gen-go suffices
• you are not using Go or protobuf APIv2
• you need a full protobuf runtime rather than a codegen helper
