AI-Powered
Protocol Buffers

Generate valid Protocol Buffer schemas from natural language descriptions. AI-powered development that actually works today.

// AI prevents breaking changes before deploy
$ protobuf-ai check user.proto --against v1.0.0

🚨 Breaking Change Detected:
✗ Field 'email' removed from message 'User'
✓ Suggestion: Deprecate field instead:
  string email = 3 [deprecated = true];
  // Use 'primary_email' field instead

AI-First Protocol Buffers, Today

Natural Language to Proto

Available Now: Describe your API in plain English and get valid proto3 schemas instantly. Real AST-based generation, not templates.

🔍

Smart Schema Analysis

Available Now: Parse and validate any protobuf schema. Detect field conflicts, suggest optimizations, and ensure best practices.

🔄

Platform Awareness

Basic conversion between protobuf formats. Full platform migration tools for seamless transitions.

🛡️

Breaking Change Detection

AI identifies breaking changes before you deploy. Suggests safe evolution paths for your schemas.

🚀

5-10x Faster Today

Proven: Generate complete service definitions in seconds. No more syntax errors. No more manual field numbering.

📈

Growing Smarter

Pattern learning, multi-language codegen, and API evolution tools. Join us in building the future.

🚀 New Launch

Introducing registry.protobuf.ai

Turn tribal knowledge into enforced standards. Our new AI-powered registry learns your team's patterns, enforces architectural decisions, and maintains context across all services.

What's Different Today

😩

Traditional: Manual & Error-Prone

Write proto by hand → Google syntax → Fix field numbers → Run linters → Fix errors → Hope it works. Average time: 20-30 minutes per service.

🚀

With AI: Natural & Fast

Describe your API → Get valid schema → AI validates & optimizes → Export to your tools. Real time saved: 15-25 minutes per service.

💰

Real Impact

Users report 70% faster protobuf development. Fewer bugs. Better schemas. AI handles the syntax, you focus on the API design.

Built For Developers Like You

Breaking Changes
Smart Generation
Semantic Search
// YOUR CHANGE
message User {
  string id = 1;
  string username = 2;
  // Removed: string email = 3;
  string primary_email = 4; // New field
  repeated string roles = 5;
}
// AI ANALYSIS
🚨 Breaking Change Detected

Field 'email' (tag 3) was removed
This breaks wire compatibility!

✅ Suggested Fix:
string email = 3 [deprecated = true];
// Clients should use primary_email

📝 Migration Path:
1. Deprecate old field
2. Add migration guide
3. Remove after 6 months
// JUST DESCRIBE WHAT YOU NEED
"Create a user service with authentication"
// AI GENERATES PERFECT PROTO
syntax = "proto3";

service UserService {
  rpc Login(LoginRequest) returns (LoginResponse);
  rpc Register(RegisterRequest) returns (User);
}

message LoginRequest {
  string email = 1;
  string password = 2;
}

message LoginResponse {
  string token = 1;
  User user = 2;
  int64 expires_at = 3;
}

message RegisterRequest {
  string email = 1;
  string password = 2;
  string username = 3;
}

message User {
  string id = 1;
  string email = 2;
  string username = 3;
  int64 created_at = 4;
}
