Twirp

Twirp is a simple RPC framework built on Protocol Buffers, created by Twitch, that generates routing and serialization code from Protobuf service definitions for Go and other languages. Similar to gRPC but runs on the standard library's net/http Server without custom HTTP server or transport implementations. Supports both binary Protobuf and JSON serialization, making debugging easy. Uses HTTP POST for all requests with URLs in the format /twirp/[Package].[Service]/[Method]. Protocol version 7 is the current stable version. Licensed under Apache 2.0.

  description: 'Twirp is a simple RPC framework with protobuf service definitions. Define your service in a .proto file and
    Twirp generates servers and clients implementing the Twirp wire protocol. Services are exposed over HTTP using POST requests
    with paths in the form /twirp/[Package].[Service]/[Method]. Supports both Protobuf binary encoding (Content-Type: application/protobuf)
    and JSON encoding (Content-Type: application/json). Includes a Go runtime and protoc-gen-twirp code generator plugin.'
