🤖 Promptware

World's first bidirectional universal code translator + production MCP framework

The Problem: Modern applications need microservices in different languages, but writing production servers is time-consuming. Code migration between languages is manual and error-prone. Teams using different languages can't easily share specifications.

The Solution: Promptware is the only framework with bidirectional code translation across 5 languages. Parse Python, Node.js, Go, Rust, or C# code to PW DSL, then generate ANY other language. Or define agents once in .pw and instantly generate production-hardened MCP servers—complete with 17.5x code amplification, 190 tool adapters, 20 cross-language translations (100% validated), and 5 production languages ready to deploy.

agent user-service
port 3000

tools: auth, storage, logger

expose user.create@v1 (
    email: string,
    name: string
) -> (
    user_id: string,
    created_at: string
)

expose user.get@v1 (
    user_id: string
) -> (
    email: string,
    name: string,
    created_at: string
)

Generates production-ready servers in any language with:

• ✅ MCP protocol implementation
• ✅ Error handling with standard codes
• ✅ Health checks (/health, /ready)
• ✅ Rate limiting & CORS
• ✅ Security headers
• ✅ Auto-generated tests
• ✅ Client SDKs

✨ Features

🔄 Universal Cross-Language Translation

Promptware is the only framework that enables true bidirectional code translation across 5 languages.

Not just code generation - universal translation:

# Parse ANY language to PW DSL (auto-detects language from file extension)
python3 reverse_parsers/cli.py server.py              # Python → PW
python3 reverse_parsers/cli.py server.js              # Node.js → PW
python3 reverse_parsers/cli.py main.go                # Go → PW
python3 reverse_parsers/cli.py main.rs                # Rust → PW
python3 reverse_parsers/cli.py Program.cs             # C# → PW

# Save to file
python3 reverse_parsers/cli.py server.py --output agent.pw

# Cross-language translation (parse → modify lang → generate)
python3 reverse_parsers/cli.py server.py --output temp.pw  # Python → PW
sed -i '' 's/lang python/lang go/' temp.pw                 # Change to Go
promptware generate temp.pw --lang go                       # PW → Go

Translation Matrix (20 combinations - 100% success rate):

	→ Python	→ Node.js	→ Go	→ Rust	→ .NET
Python	-	✅	✅	✅	✅
Node.js	✅	-	✅	✅	✅
Go	✅	✅	-	✅	✅
Rust	✅	✅	✅	-	✅
.NET	✅	✅	✅	✅	-

Use Cases:

• Polyglot Migration - Move services from Python to Go without rewriting
• Team Collaboration - Go dev and Python dev communicate via PW
• API Documentation - Parse any codebase to human-readable spec
• Code Analysis - Universal IR for static analysis tools
• Agent Communication - AI agents read ANY language, discuss in PW

PW Native Language Syntax (NEW!)

PW is now a true programming language with C-style syntax:

// Modern C-style syntax with type annotations
function add(x: int, y: int) -> int {
    return x + y;
}

function divide(numerator: int, denominator: int) -> float {
    if (denominator != 0) {
        return numerator / denominator;
    } else {
        return 0.0;
    }
}

function calculate() -> int {
    let numbers = [1, 2, 3, 4, 5];
    let total = 0;

    for (num in numbers) {
        total = total + num;
    }

    return total;
}

// Classes with constructors
class Calculator {
    result: float;

    constructor(initial_value: float) {
        self.result = initial_value;
    }

    function add(value: float) -> void {
        self.result = self.result + value;
    }

    function get_result() -> float {
        return self.result;
    }
}

Language Features:

• ✅ C-style function syntax: function name(params) -> type { body }
• ✅ Modern control flow: if (condition) { }, else { }, for (x in items) { }
• ✅ Type annotations: x: int, name: string, active: bool
• ✅ Multiple comment styles: //, /* */, #
• ✅ Classes with constructors and methods
• ✅ Arrays: [1, 2, 3], Maps: {key: "value"}
• ✅ Optional semicolons (both return x; and return x work)

Compile to any language:

# Compile to Python
promptware build calculator.pw --lang python -o calculator.py

# Compile to Go
promptware build calculator.pw --lang go -o calculator.go

• Enterprise-grade SDKs - Circuit breakers, retry logic, and connection pooling out of the box
• MCP-native architecture - First-class support for Model Context Protocol, perfect for AI agent systems

Consider alternatives when:

• You need a complex custom protocol (not JSON-RPC/MCP)
• You're building a monolithic application (not microservices)
• You require language-specific optimizations that don't fit the generated patterns
• Your team needs complete control over every line of server code

Promptware vs Alternatives:

• vs OpenAPI/Swagger - Promptware generates complete production servers with middleware AND parses existing code back to spec (bidirectional)
• vs gRPC - MCP protocol is simpler (JSON-RPC) and includes AI agent primitives; use gRPC for high-performance internal services
• vs Manual coding - 17.5x faster development with consistent patterns across languages and automatic test generation
• vs All code generators - Promptware is the ONLY tool with bidirectional translation - parse ANY language, generate ANY language

🛠️ Project Story

Promptware started as a weekend experiment to solve a real problem: translating code between languages is tedious and error-prone. What began as a simple code generator evolved into the world's first bidirectional universal code translator across 5 languages.

Built by one developer (with Claude's help) to scratch a personal itch, now shared freely with the world. No VC funding, no corporate backing—just open source software solving a real problem.

Contributions welcome. Patience appreciated. Stars celebrated. ⭐
