Open-source alternatives to Protovalidate

Modern protobuf package management

Generate message validators from .proto annotations.

Protocol Buffers is a language-neutral, platform-agnostic mechanism for serializing structured data. It provides a schema-driven toolchain that compiles declarative data definitions into type-safe source code, enabling consistent communication and strongly typed API contracts across services written in different programming languages. The project distinguishes itself through a highly efficient binary wire format that utilizes tag-based encoding and variable-width integer compression to minimize payload size and processing overhead. It supports robust evolutionary schema management, allowing d

Documentation generator plugin for Google Protocol Buffers

Prototool is a development toolkit for Protocol Buffers that provides a suite of tools for linting, formatting, and generating code from schema files. It functions as a system for managing the lifecycle of Protocol Buffer definitions through a command line interface. The toolkit distinguishes itself by providing a breaking change detector that compares different versions of definitions to identify wire or source incompatible changes. It also includes a gRPC client interface capable of invoking endpoints using JSON requests by dynamically compiling Protobuf definitions. The project covers bro
