RonyKIT

A Go toolkit for building high-performance API servers. Define your contracts once, get type-safe handlers, auto-generated docs, and client stubs — all with minimal boilerplate.

Quick Start

1. Install the scaffolding tool

go install github.com/clubpay/ronykit/ronyup@latest

2. Create a new Project/Workspace

For interactive setup, use:

rony setup

Or specify all options directly:

ronyup setup workspace -r ./my-api -m github.com/you/my-api

3. Add a service

cd my-api
ronyup setup feature -p auth -n auth -t service

4. Run it

cd cmd/service && go run .

That's it — you have a running API server with a scaffolded project structure, dependency injection, database migrations, and generated client stubs.

Using an AI-powered IDE? Set up the ronyup MCP server to let your AI assistant scaffold and implement services for you.

Hello World

Don't want scaffolding? Here's a complete API server in one file:

package main

import (
    "context"
    "os"

    "github.com/clubpay/ronykit/rony"
)

type GreetRequest struct {
    Name string `json:"name"`
}

type GreetResponse struct {
    Message string `json:"message"`
}

func Greet(ctx *rony.SUnaryCtx, in GreetRequest) (*GreetResponse, error) {
    return &GreetResponse{Message: "Hello, " + in.Name + "!"}, nil
}

func main() {
    srv := rony.NewServer(
        rony.Listen(":8080"),
        rony.WithServerName("greeter"),
        rony.WithAPIDocs("/docs"),
        rony.UseSwaggerUI(),
    )

    rony.Setup(srv, "GreeterService", rony.EmptyState(),
        rony.WithUnary(Greet,
            rony.GET("/hello/{name}"),
            rony.POST("/hello"),
        ),
    )

    _ = srv.Run(context.Background(), os.Interrupt, os.Kill)
}

curl http://localhost:8080/hello/World
# {"message":"Hello, World!"}

Open http://localhost:8080/docs for auto-generated Swagger UI.

Why RonyKit

• Type-safe handlers — request/response types are Go structs, validated at compile time
• Auto-generated API docs — Swagger UI / ReDoc / Scalar served directly from your handler types
• Client stub generation — generate Go and TypeScript clients from your service definitions
• One handler, multiple protocols — serve REST and RPC (WebSocket) from the same handler
• Production-ready scaffolding — ronyup generates projects with DI, repo layers, config, and migrations
• AI-assisted development — ronyup mcp integrates with Cursor, GoLand, and other MCP-capable IDEs
• Minimal overhead — built for performance with pluggable gateways (fasthttp, silverhttp)

AI-Powered Development with ronyup MCP

ronyup includes a built-in MCP server that lets AI assistants in your IDE scaffold workspaces, plan services, and generate implementation code — all following RonyKit best practices.

{
  "mcpServers": {
    "ronyup": {
      "command": "ronyup",
      "args": ["mcp"]
    }
  }
}

Add this to .cursor/mcp.json (Cursor) or configure via Settings (GoLand). See the full ronyup MCP Guide for details.

Performance

RonyKIT is designed for high throughput with minimal framework overhead. See the TechEmpower JSON benchmark for a reference point.
